PVE Restore CPU mismatch issue

Re: Case #07945874. Posting this here while I await response from Veeam support.

We are trying to do a restore on a PVE 9.1 system and getting an error regarding CPU compatability. The server we are trying to restore on is a spare older server so the CPU is therefore a bit older than the original running server.

From what I understand it's failing as the processor on the restore host doesn't support some features on the original server, but I would expect to be able to force it to change processor type on restore.

The error I get is:

11/01/2026 10:37:33 Failed : gfsdc1.sgoss.local : Failed to perform restore. Failed to reach the hypervisor.
