FYI this failure is fixed with
https://patchwork.kernel.org/project/kvm/cover/20230322011440.2195485-1-seanjc@xxxxxxxxxx/
which is currently on the 'kvm/next' branch. I tested it just to be sure.
The 'kvm/queue' branch doesn't contain that patch yet, and that's why
this unit test failed.
Thank you,
Emanuele
