The actual version of libvirt on the system shouldn't matter, these
tests should not be running against a real libvirt, everything should be
faked out. My guess is the tests are using unordered dicts and that's
why the keys are in a different order, or something with the way the xml
comparison code is asserting the attributes.

Title:
failing libvirt tests: need ordering
Status in OpenStack Compute (nova):
New
Status in OpenStack Compute (nova) stein series:
New
Bug description:
When rebuilding Nova from Stein in Debian Sid, I get 3 unit test
errors, probably due to a more recent libvirt (ie: 5.6.0). See for
example, on this first one:
<target bus="virtio" dev="vda"/>
we get bus= and dev= inverted.
