Nova fails to parse new libvirt mediated device name format
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The name format of mediated devices in libvirt was recently changed from
``mdev_<uuid>`` to ``mdev_<uuid>_<parent>``. For users of the new tech-preview
nova-compute-nvidia-vgpu charm, this will cause new Nova instances to enter
into an error state subsequent to a vGPU device being attached to an instance.
This is being tracked in issue `LP #1951656`_. A fix will soon be available as
an SRU.
