I have a small router vm, some kind of linux based.
If i backup with old vzdump and restore to another VMid, it boots okay.
If i backup to pbs and restore to another VMid it won't boot.

i can't come up with any good troubleshooting, if anybody have an idea or advice i would be happy to hear it.

vm config, restore log and boot pics attached

Your PBS backup might be corrupt, have you checked by verifying the backup? Is this reproducible (new backup followed by immediate restore)? Also make sure that you are running the latest versions of PBS client and PBS server.

Edit: Sorry, didn't see your included pveversions.txt

Thank you for the feedback, yes the backup is verified, I also created a new datastore on another disk, do the backup and verify, restore the vm and it won't boot so yes, it's very much reproducible.

However, you actually solved it by your feedback. I suspected the boot partition got corrupted, so only thing i did to make it work was to restore to a local lvm instead of the ceph storage running the VM. If i restore the same pbs backup that failed before to local-lvm, it boots fine. If i do a harddisk move from this restored VM back to ceph, it still boots.
Somehow the restore from pbs to ceph does something that causes only this kind of boot partition to fail. I still don't know what but i can sleep well. It haunted me to have backups i could not use.
