How to Fix KVM Error: Failed to Get Domain

Did you know that the “failed to get domain” error in KVM lets us know that the virtualization system cannot locate or access the specified virtual machine?

This issue can be due to different causes like the domain not being defined, permission issues, libvirt daemon problems, storage pool issues, and network connectivity problems.

Today, we are going to take a look at the main causes and fixes for this error.

Common Causes

1. The virtual machine does not exist or may have been deleted.
2. The user running the command might not have sufficient permissions to access the domain.
3. Problems with the libvirt daemon or its configuration could prevent access to domains.
4. Additionally, issues with the storage pool where the domain’s disk images reside can cause problems.
5. Network connectivity problems may prevent communication with the domain.

Troubleshooting Tips

1. First, check if the domain exists by running:

   virsh list –all

   If the domain doesn’t exist, recreate it or restore it from a backup.
2. Now, make sure the user running the command has the necessary permissions to manage KVM domains. Use `sudo` or adjust user permissions if required.
3. Sometimes, restarting the libvirt daemon can resolve temporary issues.

   sudo systemctl restart libvirtd

   Or use equivalent commands based on the system.
4. Then, check the status of the storage pool where the domain’s disk images are located.

   virsh pool-list
virsh pool-info <pool_name>

   Replace pool_name with the name of the storage pool.
5. Also, verify network connectivity for both the host and the virtual machine. Check network interfaces and firewall rules to ensure they are configured correctly.
6. Then, check the file system where the domain’s disk images are located is healthy. We can use `fsck` or equivalent tools to check for errors.
7. Finally, check the libvirt and system logs for more detailed error messages.
