Hi all,
I'm using openstack on Debian, with http://archive.gplhost.com/debian icehouse apt mirror.
Installing new compute nodes yesterday seems to break live migration from these new hosts. Libvirt installed version is now 1.2.7-11~bpo70+1 and seems to introduce a new cpu feature :
$ virsh capabilities :
<capabilities>
<host>
<uuid>xxxxxxxx</uuid>
<cpu>
<arch>x86_64</arch>
<model>Haswell</model>
<vendor>Intel</vendor>
<topology sockets='1' cores='4' threads='2'/>
<feature name='invtsc'/>
.....
When I try a live migrate, I get an error in the nova-compute.log of the host from which the instance should be migrating :
Live Migration failure: Requested operation is not valid: domain has CPU feature: invtsc
I googled it, and didn't find a lot of answers, mainly this post https://bugs.launchpad.net/nova/+bug/1373949 confirming that it is a libvirt issue.
Does anyone has had this issue ? Is there any workaround to be able to live-migrate from these newly installed hosts ?
Thanx
