Hello team, 

I'm facing the issue of windows instances not beeing able of retrieving
the uuid because of smbios 3.0 (qemu 8.2 on debian openstack/libvirt).
The instances are of pc-i440fx-8.2 machine type.

If I understand well since 8.1 qemu use a 64bit format for the smbios
v3 which is not handle by windows OS.

I also found some commit about handling automatically the format by qemu
on q35 machine type to resolve this bug startting to 9.0.0 version
https://gitlab.com/qemu-project/qemu/-/issues/2008 

It seems forced to 64 bit on pc-i440fx-8.1 and above while forced to 32
under.

Is there a reason to not handle it automatically on pc-i440fx machine
type?

Is it safe to keep it to 32 for machine type pc-i440fx-8.1 and above?

Cheers!
