Bug 2015745

I can reproduce this with:

qemu-kvm-6.1.0-5.el9.x86_64
libvirt-libs-7.8.0-1.el9.x86_64
kernel-5.14.0-7.el9.x86_64

I will try downgrading individual components to find out what
component causes the regression.

Bug is present in (upgraded) qemu-kvm-6.1.0-6.el9.x86_64

Bug is present in (downgraded)
qemu-kvm-6.1.0-4.el9.x86_64
qemu-kvm-6.1.0-3.el9.x86_64
qemu-kvm-6.1.0-1.el9.x86_64

Bug is NOT present in RHEL 9 Beta package
qemu-kvm-6.0.0-13.el9_b.5.x86_64

*** Bug 2027853 has been marked as a duplicate of this bug. ***

QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.

Verified with packages:
libguestfs-1.46.1-1.el9.x86_64
qemu-kvm-6.2.0-1.el9.x86_64
