Migration or Clone task fails – Virtualizor Error

Virtualizor is a well-known virtualization management panel. It helps manage VMs and containers on a server. However, sometimes we come across errors while trying to migrate or clone a VM via Virtualizor.

According to our experts, some of the commonly seen reasons behind task failures in Virtualizor include:

• Insufficient resources
• Incompatible hardware or software
• Network issues
• Data corruption

If the error arises due to SSH connection failure, these steps will help resolve the issue:

1. First, check logs in /var/log/secure of the destination node.
2. Next, save the slave settings with the SSH port for the target server and try again to ensure the error is not due to a permission issue.
3. Then, try password-less login from the Source server to the Destination with the following code:

   ssh -i /var/virtualizor/ssh-keys/id_rsa -q -p dest-port root@destinationIP
4. Now, check if PubkeyAuthentication in the destination’s ssh config is enabled. Additionally, the path in /etc/ssh/sshd_config should be :

   AuthorizedKeysFile .ssh/authorized_keys
5. Finally, try deleting keys from the Master database table, before trying again.

Additionally, our experts recommend running disk and file system checks on the VM’s disk image to identify any data corruption or inconsistencies. It is also a good idea to check if the hardware and software specifications of the destination server are compatible with the VM being migrated or cloned.
