In virtuozzo 7 we have changed disk bus from sata to scsi.
Sata is not supported in virtuozzo 7.
We don't need to support sata bus for virtuozzo in nova.
Virtuozzo 6 may work with python 2.6 only and
it's not possible to run upstream nova on virtuozzo 6.
We always use this patch in our internal infrastructure
to run openstack on virtuozzo 7.
Also in this patch we have changed tests for hypervisor version.
We don't need to check libvirt version in case of Virtuozzo hypervisor.
Because Virtuozzo 7 always has libvirt with
support of 'parallels' virt type.
