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
