[Bug 2000152] [NEW] Ubuntu 22.04 Local Volume Live Migration Issue

[Ammad Ali]

Public bug reported:

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.
