Hi
When trying to restore a linux agent backup to proxmox VE (8.4.1) using veeam b&r (12.3.2) I keep getting the error
Failed to reach the hypervisor. Error output: 400 Parameter verification failed.
boot: invalid format - format error
boot.legacy: value does not match the regex pattern
qm create <vmid> [OPTIONS]
I think it should be supported according to the docs
https://helpcenter.veeam.com/docs/agent ... tml?ver=60
Since it's LVM it does try to create two disks (as stated in the docs) and I also see both of them in the veeam logs as parameters
"scsi0":"STOR_001:95,format=raw","scsi1":"STOR_001:94,format=raw","boot":"order=scsi0,scsi1"
Restoring a windows agent backup finishes without errors.
Is there currently a limitation regarding such restores to proxmox?
Thanks

Yes sorry, case number is #07763536
I since found out that this only happens to lvm based linux systems, when veeam tries to add more than 1 disk to the vm boot order. I'm going to work with support on resolving the case and will post here again if we found the issue.
