Hi there. I would like to know which is the criteria for the inclusion of a new driver column in the Hypervisor Support Matrix . We are happy users of libvirt+Xen so we were thinking in the needed steps to promote it from group C to B (and eventually A) for Icehouse (with Russell's mail in mind ). Are we free to add such a column there and start filling up the details? Later on we will fill up a blueprint to cover all the code changes that might be needed.  https://wiki.openstack.org/wiki/HypervisorSupportMatrix  http://lists.openstack.org/pipermail/openstack-dev/2013-July/011260.html Regards, -- Álvaro López García aloga at ifca.unican.es Instituto de Física de Cantabria http://alvarolopez.github.io Ed.
