Restore Failed

Post by MarkBoothmaa » Sep 22, 2018 9:49 am

My Client is having issues restoring hyper-vm after having to restore the vm config file.

The vm's are registered fine in hyper-v and failover cluster manager.

When try a restore prior to the config file restore they are getting
Failed to find virtual machine owner host: Failed to get cluster resource group.
Failed to get VM owner by ID.

Is there a quick fix for this? I know in vmware we can just rescan the host but that doesn't seem to work here

Any thoughts / guidance appreciated
Thanks
Mark

Do I get it correctly, that you restore the VM and Veeam registers it. Then you end up with the error at boot. You then restore the config file as file and it works?

The client backed up the VM's normally and then the config files were corrupted. We restored the config files and re-imported the VM.

When I went to restore the guest files after rescanning the host it told me it couldn't find the vm object ID.

OK... now it is clear what happened. Thank you.

If you register the VM again, it will get a new ID and file restore to original will not work from older backups, as they can not find the VM anymore. You can restore files with "Copy to" if needed.

The question is why the config file went corrupt?
How did you restore the files? With Veeam?
I am just guessing here, if you have damaged your configuration files and restore them with Veeam (VM File Restore https://helpcenter.veeam.com/docs/backu ... tml?ver=95) no VM registration is needed and you can start the VM again?

Ahh that makes sense. The config file was hit by ransomware :( so Hyper-v couldn't read the config files. We restored the config files only from backup.I never thought of copy too.

Thanks for the pointers.

Everything is back up and running now thankfully :)
