What is cloud computing used for?What is cloud computing used for?

Nebius Israel provides scalable computing capacity: you can quickly create and start virtual machines on demand and stop them when the load decreases. The usage of cloud resources reduces your IT infrastructure costs because you pay only for the resources you use.

It is easier to manage a cloud infrastructure so you can focus on your business challenges instead of server maintenance.

What can I do with a Nebius Israel VM?What can I do with a Nebius Israel VM?

• Use only those computing resources which are necessary to meet your needs. If you need expensive powerful systems, you don't have to buy them. You can create a VM in Nebius Israel and use it whenever necessary.

• Quickly scale processing capacity to meet your needs. You can start additional VMs during peak times and stop them when the load decreases.

• Use your VMs to deploy applications that must always be available. You don't need to worry about guaranteeing server uptime: Nebius Israel will keep it running smoothly. Focus on creating applications that work.

• Configure backups to make it easier to restore your data in the event of loss.

• Create and distribute VM disk images. You can use images to quickly deploy your software on other VMs.

• Automate VM management using the API and scripts in the command line interface.

For more information about Nebius Israel VMs, see VMs in Compute Cloud.

How do Nebius Israel VMs differ from regular hosting?How do Nebius Israel VMs differ from regular hosting?

Traditional hosting offers you resources on lease with pre-agreed performance for a fixed time. Nebius Israel VMs allow you to use cloud resources as your personal data center. At the same time, you get all the advantages of the fault tolerant infrastructure Nebius Israel data centers provide.

You can scale your cloud infrastructure as your performance requirements change. This way you can control how many resources you are using at any given time and how much you pay for them.

You will also have complete control over the VM status. You can start and stop VMs when you need to. You can set up your VM software configuration and change it as required. Disk images and snapshots allow you to easily transfer data between your VMs.

How do I get started with a Nebius Israel VM?How do I get started with a Nebius Israel VM?

You can create your first VM by following one of the scenarios described in Getting started with Compute Cloud.

How do I get access to a VM?How do I get access to a VM?

You can connect to a VM from another VM on the same cloud network. Use the VM's internal IP address or FQDN to do this.

If you assigned a VM a public IP during creation, you can use that IP to connect to the VM from the internet.

You can get the IP addresses, FQDNs, and other information in the management console in to the Network section on the VM's page.

For more information, see VM networking.

Use SSH to connect to a Linux VM. Use RDP to connect to a Windows VM.

How quickly can I change the performance of my information systems?How quickly can I change the performance of my information systems?

You can change the performance of your information system in one of the following ways:

• Create VMs in advance with the appropriate configuration and pre-installed software. During peak times, all you have to do is start these VMs to increase the performance of the information system. When the load decreases, you can stop some of the VMs to avoid paying for extra resources.
• If you frequently need new VMs with the same configuration, you can create a boot disk image and use it when creating VMs.

Why is my VM slow?Why is my VM slow?

Just like for any other servers, including physical ones, VM performance depends on the performance of:

• CPU
• RAM
• Disks
• Network

Please note: The physical core thread allocated to your VM handles, in addition to the vCPU itself, the qemu virtualization process and I/O operations (network and disk ones).

General recommendations for improving VM performance:

1. For product solutions, use a vCPU with a guaranteed performance of at least 100%. If you use a vCPU with performance below 100%, the vCPU performance may drop to the guaranteed level when "neighbors" appear on the physical core. For example, for a share of 5%, this is only about 100 MHz of clock frequency, which is most likely insufficient for a product server.

   If the graphs show that the load on the vCPU is close to 100% for a long time or at the time the issue occurs, we recommend increasing the number of cores.

2. Never use the swap file. It causes a significant drop in performance. The best solution is to expand the vRAM if there is not enough memory. With Linux, you can also use the zram-config utility.

3. Use large network SSDs. The weak point of the system may be network drives. They are subject to the limits of IOPS and bandwidth, which depend on the disk type and size. For more information, see Disk limits.

   Keep in mind that disk performance also depends on the read and write request size. See Read and write operations.

   You should read and write data in several threads.

4. Note that network computing depends on the vCPU performance. Run synthetic tests that do not affect disk usage to diagnose network problems. If it does have to do with a slow network, we recommend adding a vCPU and retesting it.

Which operating systems are supported by Nebius Israel VMs?Which operating systems are supported by Nebius Israel VMs?

How do I create a multi-interface VM?How do I create a multi-interface VM?

You can add a network interface only when creating a VM. Currently, multiple interfaces can be created only on network images from Cloud Marketplace.

You can also create a NAT instance to use multiple network interfaces.

VM parametersVM parameters

How do I increase quotas?How do I increase quotas?

If you need more resources, you can increase quotas in one of the following ways:

• Generate a request for a quota increase. You must have the quota-manager.requestOperator role or higher, such as editor or admin.
• Contact support and tell us which quotas you need to increase and by how much.

After creating the request, the message appears in the support center where you can track its status. In some cases, it may be necessary to get approval from the service to ensure the availability of resources and/or to increase your account balance.

Is nested virtualization supported? Can I host my VMs inside other VMs?Is nested virtualization supported? Can I host my VMs inside other VMs?

Nested virtualization is not supported for security reasons. If you did not find a suitable public image for a VM, you can upload your own image and create a VM based on it. Follow this guide: Creating a VM from a custom image.

Is data saved when I edit my VM parameters?Is data saved when I edit my VM parameters?

Yes, the data should be saved. However, please note that you should not restart your VM when writing data to the system disk because this might result in file system corruption.

To edit the parameters of your VM, follow these steps:

1. Take a snapshot of the disk: see Creating a disk snapshot.
2. Shut down the VM normally: see Stopping, starting, or restarting a VM.
3. Edit the VM parameters: see Changing VM computing resources.
4. Wait until the operation is completed (the Operations section in the Compute Cloud service).
5. Start the VM.
6. Make sure that the new parameters were applied.

Can I reduce vCPU or vRAM for a VM?Can I reduce vCPU or vRAM for a VM?

Yes, you can. However, if the load on the vCPU and/or vRAM was high enough when you changed the parameters, the VM may fail to start if you decrease these parameters.

If the load on the server is small and uniform, we recommend decreasing the parameters to avoid extra charges.

Can I change the FQDN?Can I change the FQDN?

The FQDN is issued to the VM at the time of its creation, and you cannot change it.

If you want to change the FQDN, delete the VM and create a new one. To preserve the consistency of the data:

1. Stop the VM: see Stop.
2. Take a snapshot of the disk: see Creating a disk snapshot.
3. Create a new VM by selecting the snapshot as the source of its boot disk: see Create a VM with disks restored from snapshots. Specify the FQDN you need during creation.

Can the UUID of a VM change?Can the UUID of a VM change?

Standard operations for changing VM configuration, such as changing the number of vCPUs, the amount of vRAM, and adding disks, will not affect the UUID. However, in some cases, the UUID may change. For example, this may happen when updating BIOS or performing similar operations that affect the hardware part of the service.

Keep this in mind when using third-party software licenses. The best solution is to purchase a license that does not have any link to the UUID.

How do I change metadata after creating a VM?How do I change metadata after creating a VM?

Use the updateMetadata API method.

This method enables you to update the metadata in the service without affecting the guest operating system run by the VM. If you need to update a parameter inside your VM after its creation, in most cases, the best way is to recreate the VM from a snapshot or make changes manually.

VM operationsVM operations

Can I copy or clone an existing VM?Can I copy or clone an existing VM?

Yes, you can take snapshots of the disks attached to a VM and use them when creating a new VM.

Can I move my VM to a different folder?Can I move my VM to a different folder?

You can move a VM to another folder within a single cloud. For more information, see Moving a VM to another folder.

If I accidentally delete my VM, can I restore it?If I accidentally delete my VM, can I restore it?

No, you cannot. If you delete a VM, this cannot be undone.

To avoid losing your data in case of accidental deletion, you can configure disk backups using snapshots or specify that the disks should not be automatically deleted when deleting the VM.

ConnectionConnection

How do I connect to a VM running Windows Server?How do I connect to a VM running Windows Server?

See: Connecting to a Windows VM via RDP.

For the first connection, use the Administrator account. You may want to choose a strong password for this account and create another account to use for connections on a regular basis.

For images without additional Remote Desktop Services licenses, a maximum of two simultaneous RDP connections are possible.

How do I connect to a Linux VM?How do I connect to a Linux VM?

See: Connecting to a Linux VM via SSH. If the computer you are connecting from has an older version of Windows (7, 8, or the first releases of Windows 10) and there is no built-in SSH console client, use PuTTY.

The Linux images from Nebius Israel are initially supplied without a graphical shell. Connection via SSH using a username and a password is disabled by default because this method is outdated and unsafe.

What should I do if I can't connect after creating a VM?What should I do if I can't connect after creating a VM?

Your device should see the VM over the network:

• If you are connecting from the outside, you need to have a public IP address assigned to the VM or configure connectivity through another VM with a public IP address (e.g., through a NAT instance).
• Outgoing traffic to and from the VM must be allowed on your device.

Do not turn off or restart the VM immediately after creating it. For VMs with a small guaranteed vCPU performance, the initial launch process may take a long time (up to half an hour). If the VM is terminated prematurely, the initialization scripts might not have time to execute. In this case, delete the VM and create a new one.

How do I use root on a Linux VM?How do I use root on a Linux VM?

When creating a Linux VM, do not use usernames reserved by the system, such as root, admin, etc, because cloud-init will not be able to add a user with this kind of username. Try creating a VM by specifying the user username instead.

To upgrade your rights to root, use sudo. The user specified when creating the VM is a member of the sudo group. root doesn't have a password, so you can simply connect to the VM via SSH (see Connecting to a Linux VM via SSH) and enter the command:

sudo su

You can also execute various commands without switching to root. For example, to shut down a VM from the guest OS, just enter the command:

sudo poweroff

What should I do if I can't connect to the VM, even though the connection was working before?What should I do if I can't connect to the VM, even though the connection was working before?

Your data was likely taken over and third parties gained access to the VM. Take a snapshot of the VM's disk (see Creating a disk snapshot) and create a new VM from it (see Create a VM with disks restored from snapshots). If you were able to connect to the new VM, use stronger passwords and don't share your private data.

If the VM created from the snapshot is also unavailable for connection, see How do I get important data from a broken VM.

What should I do if I can't connect to a VM from the Cloud Marketplace image?What should I do if I can't connect to a VM from the Cloud Marketplace image?

Some Cloud Marketplace images have service usernames reserved, such as bitrix in the 1C-Bitrix image. When creating a VM and connecting to it, make sure to use a username that is not reserved in the system, like user. Do not use root, admin, or other system usernames.

You can later change the bitrix user's password by running the sudo passwd bitrix command.

How do I set up an RDP/VNC connection to a Linux VM?How do I set up an RDP/VNC connection to a Linux VM?

There are two options for enabling the graphical interface on Linux VMs:

• Use RDP or VNC. To do this:

  1. Install the desktop environment on a Linux-based VM (Ubuntu/CentOS).

  2. Install the xrdp or VNC server to connect via RDP or VNC, respectively.

  3. Configure the software.

     We recommend using a combination of a VNC server that only listens to localhost and an SSH tunnel. In this case, you eliminate the risk of attackers connecting to your VM via VNC and also encrypt the VNC traffic.

• Configure X11 forwarding onto the local computer. For Windows, use Xming.
  1. Install the desktop environment.
  2. Configure X11 forwarding and connect via SSH.
  3. Launch the application from the terminal.

What should I do if I can't connect to the VM, even though the connection was working before?What should I do if I can't connect to the VM, even though the connection was working before?

Your data was likely taken over and third parties gained access to the VM. Take a snapshot of the VM's disk (see Creating a disk snapshot) and create a new VM from it (see Create a VM with disks restored from snapshots). If you were able to connect to the new VM, use stronger passwords and don't share your private data.

If the VM created from the snapshot is also unavailable for connection, see How do I get important data from a broken VM.

How do I use a serial console? How do I connect directly to a VM?How do I use a serial console? How do I connect directly to a VM?

If you have issues while connecting to a VM over a network, you can use the serial console. For more information about charts, see Getting started with the serial console.

You can enable access to the serial console when creating or modifying a VM. The serial console is available in the Nebius Israel management console in the VM menu.

For a Linux VM, you need to additionally configure password access for the user in advance by connecting via SSH and setting a password with the sudo passwd user command, where user is the username you set when creating the VM.

What do I do if an SSH key is lost?What do I do if an SSH key is lost?

If you set a user password, configure the VM serial console and connect to it. We recommend connecting through the CLI.

If no user password is set, take a snapshot of the VM's disk and create a new VM from the snapshot.

If the problem persists:

1. Create a new disk from the VM snapshot.
2. Attach it as a secondary disk to a different VM.
3. Change the root directory with chroot.
4. Edit the configuration files that make the VM unavailable.
5. Detach the disk from the VM.
6. Create a new VM. Under Image/boot disk selection, go to the Custom tab and select your disk as the boot disk.

Why does the VM not work after a reboot?Why does the VM not work after a reboot?

The VM may stop working after a reboot for one of the following reasons:

• The VM was forcibly restarted while writing to the system disk. In this case, the file system could be damaged.
• The firewall and/or network was incorrectly configured.
• Changes were made to the cloud-init settings.
• Changes were made to the Python system version, which is also used by cloud-init.
• There was a problem with the service.

If you performed one of these actions, see How do I get important data from a broken VM. Otherwise, contact support.

How do I get important data from a VM that crashed?How do I get important data from a VM that crashed?

When a VM crashes:

1. Take a snapshot of the problematic disk (see Creating a disk snapshot for details).
2. Create a new VM with an additional (non-bootable) disk that was restored from the snapshot (see Create a VM with disks restored from snapshots for details).
3. Connect to the VM (see Working on VMs for details).
4. Mount the disk (see Mounting a disk created from a snapshot or image for details).
5. Run a check of the disk file system.
6. Transfer the data you need to the boot disk of your new VM.

How much disk space can I use for a virtual machine?How much disk space can I use for a virtual machine?

For disk limitations, see Quotas and limits in Compute Cloud.

How do I change the size of a disk?How do I change the size of a disk?

You can increase your disk size within the limits by following the instructions Increasing disk size. The data on the disk is kept. Make sure to wait until the operation is complete.

However, the architecture of technologies used in Nebius Israel doesn't enable you to decrease the disk size. It's also impossible to create from the snapshot a disk smaller than the parent disk.

If the partition on the Linux boot disk doesn't expand automatically after increasing the disk size, use the following commands:

sudo growpart /dev/vda 2

sudo resize2fs /dev/vda2

For non-bootable disks, the partition size won't expand automatically. Use standard OS tools for this purpose (for example, parted).

How do I upload a custom image?How do I upload a custom image?

Follow this guide: Uploading a disk image to Nebius Israel.

To ensure that the VM created from your image functions properly, follow the steps specified in the guide.

If you have followed all recommendations and the image still fails to start up, or in case you have other questions, contact support.

What happens to the VMs running outdated OS versions?What happens to the VMs running outdated OS versions?

You can use images with outdated OS versions on your VMs; however, you will not be able to get support for these VMs if you have any issues.

Should I use swap?Should I use swap?

Avoid using swap in cloud systems whenever possible because the disk subsystem can become a bottleneck for the entire guest system. Network disk limits are too low to use the disk as a RAM extension.

Instead of swap, you can use the zram-config utility. It allows you to organize a kind of swap inside the RAM itself thanks to compression, which is ten times faster than I/O with a disk. Keep in mind that with a high load on I/O and/or vCPUs, the use of zram-config may negatively affect iowait and, consequently, the performance of the network, disks, and vCPUs.

The best solution for increasing available memory is to expand the vRAM on the VM.

What should I do if a snapshot is larger than the data on the disk?What should I do if a snapshot is larger than the data on the disk?

This happens if occupied sectors remain on a disk after you delete files from it.

The solution is to write a file consisting of zeros to the entire unoccupied disk space, then flush the cache to the disk, and delete the record about this file.

• For Windows: stop disk operations and use the SDelete utility. You can learn more about the utility and download it in the Microsoft documentation.

• For Linux: stop disk operations and enter the following commands one-by-one:

  dd if=/dev/zero | pv > full.disk
  

  sync
  

  rm full.disk
  

The "empty" space on the disk then becomes truly empty and you can create a disk snapshot. Its size will become closer to the currently used disk space.

Can I create several snapshots of the same disk at a time?Can I create several snapshots of the same disk at a time?

No, only a single snapshot can be created for one disk at a time. All other schedules for a given disk are ignored until a snapshot for this disk is created (manually or as scheduled).

How are snapshot quotas counted?How are snapshot quotas counted?

Snapshots are billable and count towards quotas with their actual sizes.

How do I move a VM to another folder/cloud?How do I move a VM to another folder/cloud?

1. Grant rights in your cloud to a user from another cloud:

   • Role for the cloud: resource-manager.clouds.member.
   • Role for the folder: viewer or compute.images.user.

   See also the instructions Assigning roles.

2. Create an image from your snapshot under Snapshots or from the disk itself under Disks.

A user in another cloud must:

1. Run the CLI command below:

   yc compute image create --source-image-id=<your_image_ID>
   

2. When creating a VM, specify this image as a boot disk.

How do I attach a new disk to a VM?How do I attach a new disk to a VM?

After creating and connecting a new disk to the VM, you need to mount it or assign it a letter, depending on the operating system. Follow this guide: Mounting a disk created from a snapshot or image.

How do I set up automatic backups?How do I set up automatic backups?

For disk backups in Compute Cloud, you can make disk copies — snapshots. For automatic creation of snapshots, use schedules.

For more information, see Backups in Compute Cloud.

Why was a disk snapshot created later rather than exactly at the scheduled time?Why was a disk snapshot created later rather than exactly at the scheduled time?

Scheduled snapshots may be created with a slight delay depending on the current load on the service.

Can I create snapshots of the same disk according to several schedules?Can I create snapshots of the same disk according to several schedules?

Yes, you can add a disk to several schedules. There are fixed limits on the number of disk schedules.

In what time zone is the time written in disk snapshot schedule settings?In what time zone is the time written in disk snapshot schedule settings?

The time is provided for the UTC time zone.

Can I choose a folder for scheduled disk snapshots?Can I choose a folder for scheduled disk snapshots?

Snapshots are created in the same folder as the schedule, even if disks from other folders are added to the schedule.

What format of cron expressions is supported in disk snapshot schedules?What format of cron expressions is supported in disk snapshot schedules?

See section Cron expressions.

If the schedule is configured to keep several of the last disk snapshots, are old snapshots deleted before or after new ones are created?If the schedule is configured to keep several of the last disk snapshots, are old snapshots deleted before or after new ones are created?

After. A new snapshot is created first, then the old one is deleted. For example, if you want to keep only the last five snapshots, the first snapshot is deleted after the sixth one is created, the second is deleted after the seventh one is created, etc.

What happens to operations and created snapshots when disk snapshot schedules are changed, interrupted, or deleted?What happens to operations and created snapshots when disk snapshot schedules are changed, interrupted, or deleted?

All snapshot creation or deletion operations that started prior to changing, interrupting or deleting the schedule will be completed. Snapshots that were not deleted according to schedule retention settings are kept.

What happens to my data when I delete a virtual machine?What happens to my data when I delete a virtual machine?

When selecting a disk to attach to a VM, you can specify that the disk should be deleted once you delete the VM. This option is also available when you create a VM, reconfigure it, or attach a new disk to it.

If a VM had any previously created disks attached, they will be detached when you delete the VM. The disk data is preserved, and this disk can be attached to another VM later.

If you would like to delete a disk with a VM, specify this option when creating the VM, reconfiguring it, or attaching the disk. Such disks will be deleted along with the VM.

Do I need to stop a VM to create disk snapshots? Do I have to wait until disk snapshots are created before I can start a virtual machine?Do I need to stop a VM to create disk snapshots? Do I have to wait until disk snapshots are created before I can start a virtual machine?

You don't have to stop the VM. However, keep in mind that a snapshot contains only the data written to disk when creating the snapshot. You need to take care of the data integrity yourself. For information about how to create disk snapshots, see Creating a disk snapshot.

A snapshot is created asynchronously. You can resume writing data to a disk immediately after running the create snapshot command, without waiting for the snapshot creation to be completed.

How do I detect processes that put a heavy load on a disk?How do I detect processes that put a heavy load on a disk?

You can detect these processes using the iotop utility. Run it on a schedule with cron and save a log with processes that have a data transfer speed of more than 1000 KB/s:

/usr/sbin/iotop -botqqqk --iter=60 | grep -P "\d\d\d\d.\d\d K/s" >> /var/log/iotop.log

Instance groupsInstance groups

What is Instance Groups?What is Instance Groups?

Instance Groups is a component that allows you to create, use, and scale groups of similar instances in the Compute Cloud infrastructure.

With Instance Groups, you can:

• Create groups with the required number of instances and performance parameters.
• Scale the computing capacity up or down, depending on the load.

You work with an instance group as a single entity in the Compute Cloud infrastructure. This allows you to manage the internal settings of the instance group to meet your application's requirements.

How is the cost of instance group use calculated?How is the cost of instance group use calculated?

Creation of an instance group is free of charge.

All other Nebius Israel services, such as VMs and external IP addresses, are charged as usual.

How do I know I'm not overpaying?How do I know I'm not overpaying?

To select the appropriate number of instances and minimize costs:

• Estimate the amount of computing resources required for your service and see the calculation examples and pricing policy for Compute Cloud.
• Try to frequently monitor the load on the service at different times of day.

Why can't I delete a service account linked to an instance group?Why can't I delete a service account linked to an instance group?

You cannot delete a service account used to manage an instance group while it is linked to this group. First, update the service account in the instance group settings or delete the instance group and then delete the service account.

Monitoring resource usageMonitoring resource usage

Why does vCPU utilization displayed on the chart exceed 100%?Why does vCPU utilization displayed on the chart exceed 100%?

If you use cores with guaranteed, say, 5% vCPU performance, then this 5% represents 100% of the expected load for the monitoring system. If there are no "neighbors" on the physical core, you can be allocated up to 100% of vCPU performance, which is 20 times higher than the maximum expected load (×20 of 5%). Thus, the chart can show up to 2000%.

If you see the upper limit of 100% exceeded for quite a while in the graphs, we recommend increasing the guaranteed vCPU performance because "neighbors" may appear on the physical core at any time and your real utilization of physical core resources will drop to the guaranteed 5% (about 100 MHz). In this case, the guest system may not cope with the load and you'll lose access to the VM.

How do I track vRAM use through monitoring?How do I track vRAM use through monitoring?

The Compute Cloud service can't measure vRAM consumption inside the guest operating system because for the service, memory consumption by the virtual machine is always the same: the one that is allocated the moment it is started.

To track the vRAM state, use the Monitoring service. It allows you to record your own metrics. See Writing custom metrics via the API. Just schedule a task to download data about the vRAM state and Monitoring will display them.

Can I deploy my own Windows Server licenses in Compute Cloud?Can I deploy my own Windows Server licenses in Compute Cloud?

Yes, under the Flexible Virtualization Benefit you can deploy your own Windows Server licenses if you have a subscription license or active Software Assurance and meet Microsoft licensing terms for your own license.

You must allocate as many licenses as there are processor cores (vCPUs) allocated to your VMs with Windows Server, but not less than eight licenses per VM and 16 licenses in total. Also, for each VM you must allocate a Client Access License (CAL) to each user or device accessing Windows Server running in the VM. All licenses, including CALs, must be subscription licenses or licenses with active Software Assurance.
