Title:
  Qemu min version validation fails on Xenial with Qemu 2.11.1

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Novas Qemu min version validation  fails on our CI systems. Please
  note that i added some additional debug output prior to the exception
  message showing the installed Qemu version is 2.11.1 (which is
  correctly picked up by the libvirt lib). Somehow Nova fails to
  acknowledge version 2.11.1 is >= 2.5.0 . Log excerpt from
  devstack@n-cpu service log in our Devstack:

  EBUG nova.virt.libvirt.host [None req-be3dfd79-9035-443c-bf60-ac83e7c1b290 None None] HYPERVISOR VERSION IS 2011001 {{(pid=7926) _version_check /opt/stack/nova/nova/virt/libvirt/host.py:496}}

  I'm looking into the validation code right now but wanted to raise a
  flag already. Maybe i'm overlooking something?
