Unikraft would a a good fit for ram-constained devices.
Being able to have useful VMs with 32-64 MB each.

RE: RealTimeIsUniversal - Windows VM - PV driver does not work
@jiri.hadamek Yes, it's a driver bug. I'll plan for a fix.

RE: Win11 24H2 install fails consistently
If the host is really old I'd also check Windows 11 version 24H2 supported Intel processors

RE: VM UUID via dmidecode does not match VM ID in xen-orchestra
@deefdragon said in VM UUID via dmidecode does not match VM ID in xen-orchestra:
Out of curiosity, I dumped the DMI into a bin and opened it up in a hex editor.
I am seeing ASCII of the ID, but also a variant encoded in binary. In both cases, its formatted as
0b08f477-491a-a982-23c4-d224723624ea.I believe the ASCII version is the one that gets populated into the serial number as it comes after ASCII encoded versions of the 3 lines above it in the decode.
In SMBIOS 2.8, the UUID is supposed to be encoded in little endian (i.e Microsoft GUID). Yet it is put as big endian instead. So when Linux generates the UUID string from the SMBIOS table, it is considered as little endian which causes this mismatch.
SMBIOS 2.4 is supposed to be used (which appears to be using big endian UUIDs), but for some reason, something in XCP-ng UEFI supports forces it to be SMBIOS 2.8.
So the binary UUID is the same, just that it is interpreted with a different endianness due to accidental format change.

RE: Large "steal time" inside VMs but host CPU is not overloaded
@lovvel from a software standpoint, this is a 16 cores CPUs and AFAICT, Xen doesn't account for these slight differences between cores.
As to be fair, it's not really easy to know in practice if a 3D-VCache core will be faster than a non-3D-VCache one for a specific case.
