VM statuses

List of statusesList of statuses

A VM can have one of the following statuses:

• PROVISIONING: Yandex Cloud is allocating resources to the VM.
• STARTING: VM is being started.
• RUNNING: VM has been started and is running.
• STOPPING: VM is being stopped.
• STOPPED: VM has been stopped.
• RESTARTING: VM is being restarted.
• UPDATING: VM is being updated.
• CRASHED: VM crashed and will be restarted automatically.
• ERROR: Fatal error occurred and the VM cannot be recovered.
• DELETING: VM is being deleted.

Operations on a VMOperations on a VM

The diagram below shows only switching statuses under normal operation during the following actions:

• VM creation
• VM stop and start
• VM restart

The diagram does not show the following intermediate statuses:

• UPDATING (update)
• DELETING (deletion)
• CRASHED and ERROR (errors)

CreationCreation

When a VM is created, it gets the PROVISIONING status. At this stage, the VM is allocated computing resources, such as the number and performance of processor cores (vCPUs) and the amount of RAM. It is also assigned an IP address and gets its disks created.

After this, the VM will automatically start and switch to the STARTING status.

If the startup is successful, the VM's status will change to RUNNING and the operating system will start loading. Once this is complete, you will be able to connect to your VM.

Stop and startStop and start

When a VM stops, the hypervisor sends a shutdown signal to the VM operating system. The OS needs to terminate the current processes nice and easy within the next 30 seconds to avoid data loss. When this time expires, the VM process is forced to stop, and the VM gets the STOPPED status.

At the next start, the VM will go through the same statuses as when it was created: PROVISIONING → STARTING → RUNNING.

RestartRestart

When being restarted, the VM switches to the RESTARTING status. Since all computing resources have been already allocated for it, it will go back to the RUNNING status once it is restarted.

UpdatingUpdating

You can update the VM parameters, such as change its name, regardless of the VM status. Once updated (the UPDATING status), the VM will go back to the previous status.

If you update the metadata, it will be available from inside the VM immediately after the update. You do not need to stop or restart the VM in this case.

DeleteDelete

When you delete a VM, all ongoing operations are first cancelled or stopped, and then the VM switches to the DELETING status.

When the deletion is complete, the VM disappears from the list of available resources.

ErrorsErrors

There are two error statuses:

• CRASHED: Error occurred and the VM cannot continue working.

  If the VM has switched to this status, Yandex Cloud will try to restart it. Restart attempts will be repeated until the VM status changes to RUNNING or ERROR.

• ERROR: Fatal error occurred and the VM cannot be recovered.

  If the VM has switched to this status or is continuously switching to the CRASHED status, contact technical support or create a new VM.
