On AArch64 we use cpu_mode='host-passthrought' which should allow us to do live migration between compute nodes running same cpus.
But it does not:
------------------------------------------------------------------------------------------------------estuary@ref-compute-2:~$ openstack server migrate --live ref-compute-1 --wait 38da6986-2f76-486d-877b-438560d7aa05
Migration pre-check error: CPU doesn't have compatibility.
XML error: Missing CPU model name
Refer to http://libvirt.org/html/libvirt-libvirt-host.html#virCPUCompareResult (HTTP 400) (Request-ID: req-cea6f860-e78b-469b-9527-a703114b372b)
-------------------------------------------------------------------------------------
virsh itself is able to live migrate between two XGene1 nodes:
-------------------------------------------------------------------------------------
root@cb-r1-m1-c1n1:/var/log/libvirt# virsh migrate --copy-storage-all --live debian-cloud-image qemu+ssh://root@10.101.3.103/system tcp://10.101.3.103

root@debian:/var/lib/libvirt/images# virsh list --all

Will dig more to find out what, where and why is wrong.
