Summary0005710: Live migration between VM booted on qemu-kvm-7.2.0-14.el9_2.5 and qemu-kvm-8.0.0-16.el9_3.3 fails
DescriptionI've got a VM booted using libvirt (via OpenStack):

The error I am seeing when trying to migrate the VM is:

2024-02-08T09:39:19.788241Z qemu-kvm: Features 0x10130afffaf unsupported. Allowed features: 0x179bfffef

2024-02-08 09:39:19.992+0000: shutting down, reason=crashed

I've attached the libvirt definition. Any idea what is causing the failure?

libvirt version: libvirt-daemon-9.5.0-7.el9_3.x86_64

Turns out the issue was that the destination hypervisor was running and older kernel:

Linux cpt01 5.14.0-284.25.1.el9_2.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Aug 2 14:53:30 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
