Ubuntu 22.04 Local Volume Live Migration Issue

[Ammad Ali]

Hi,

Using ubuntu 22.04 LTS and setup openstack yoga on it. The live migration of cinder backed volumes are successful but the migration of local volume (i.e root disks resides on local compute storage) goes fail. However the migration works fine on ubuntu 20.04 yoga release from UCA with qemu 4.2 and libvirt 8.0. Issue looks to be in below qemu version.

Qemu 6.2 (default in ubuntu 22.04)
Libvirt 8.0 (default in ubuntu 22.04)

The migration of local storage instance are getting failed with below error in nova-compute logs. I think the error is being thrown from libvirt.
