resume_guests_state_on_host_boot = True creates libvirt.xml with empty nova:owner

[György Szombathelyi]

When instances are booted automatically after a compute reboot, the libvirt.xml-s are recreated withot the nova:owner data. And ceilometer likes use it.

The relevant part of the xml after the reboot:
.
.
      </nova:flavor>
      <nova:owner/>
      <nova:root type="image" uuid="98199656-154f-4481-8ee9-b5480c9f9b8b"/>
    </nova:instance>
  </metadata>
.
.
At the first sight, the owner metadata is created in _get_guest_config_meta in virt/libvirt/driver.py, but only when context is not None. But when nova starts the guests on its own, probably it is None?

Ok, seems it is already reported and fixed (just not with resume_guest_state_on_host_boot).
