I made a minor tweak (in virDomainDiskDefFormat, I split the initial
<mirror type='...' ready='...'> into two actions, per your comment
on
9/10), and pushed this one.
On IRC, John pointed out that this change tripped up the libvirt
regression testsuite (so there IS code depending on the older <mirror
file='/path/to/file'/> notation), and danpb convinced me I need to
provide the older semantics even while adding newer semantics, so as not
to break older clients. I'll be preparing a followup patch.
