Thanks Daniel.  We will be proposing an update to the powervm driver today 
handle this change.

Appreciate you reaching out about this!

Subject:        [openstack-dev] [nova][docker][powervm] out of tree virt 
driver  breakage

This is an alert for anyone who maintains an out of tree virt driver
for Nova (docker & powervm are the 2 I know of).

The following change has just merged changing the nova/virt/driver.py
API, and as such it will break any out of tree virt drivers until they
are updated

    compute: convert manager to use nova.objects.ImageMeta
    Update the virt driver API so that all methods with an
    'image_meta' parameter take a nova.objects.ImageMeta
    instance instead of a dict.
    NB, this will break out of tree virt drivers until they
    convert their code to use the new object.

Anywhere in your virt driver impl that uses the 'image_meta' parameter
should be updated to use the nova.objects.ImageMeta instance rather
than assuming it has a dict.

If you have any trouble understanding how to update the code, reply
to this message or find me on IRC for guidance, or look at changes
made to the libvirt/xenapi/vmware drivers in tree.
