One of our VM clusters has four CentOS 6.6 machines. I'm in the
process of testing the addition of a CentOS 7 box (with the goal of
upgrading the 6.6 machines soon).
A newly created VM running on a 6.6 node has a machine type of
rhel6.6.0:
<os>
<type arch='x86_64'
machine='rhel6.6.0'>hvm</type>
<boot dev='hd'/>
</os>
The libvirt on the CentOS 7 machine won't recognize that label; it
goes straight from rhel6.5.0 to the newer RHEL 7 types:
pc-i440fx-rhel7.0.0 and pc-q35-rhel7.0.0.
I can shutdown the VM, edit its XML definition, restart it, and then
migrate it -- but I'd rather be able to do a live migration without a
shutdown.
Has anyone else seen this? Any workarounds?
