i have a bunch of windows machiens on PVE 8 that i suddenly realize don't see their UUID, even though proxmox did assign them one in the options>bios. this is preventing certain software from functioning. is there additional config i need to do for the machines to see the uuid? additional proxmox config?
 
Judging by another topic [1] I found, this might be related to a combination of using machine-version 8.1 combined with legacy bios booting.

At a glance it looks like your options are:
- Add the machine argument "-machine smbios-entry-point-type=32"
- Switch (back) to machine version 8.0
- Switch to UEFI/GPT for your system instead (might also fix some other issues, see [2] also for the commands to do that switch)

Of course, clone/backup/test properly, messing with (virtual) hardware always has the risk of breaking things ;)

got it. changing the machine hardware version back fro 8.1 to 8 fixed it. it also seems like the proxmox dev's are aware of the issue, and it's in active discussion. thanks for dropping by!
