commit 309e14189fa1c470977f3a4bccc5456b390d4cce
Author: Richard W.M. Jones <rjones at redhat.com>
Date: Wed Jul 1 18:04:46 2015 +0100
v2v: Pass target_buses to output object (RHBZ#1238053).
Pass the target_buses assignment to the output#create_metadata method.
Now output modes have a choice: they can either ignore the new
parameter and continue to use the flat list of targets. This is
suitable for output modes that cannot model multiple buses (eg.
-o glance) or can model it but don't bother (currently -o rhev).
Or they can ignore the flat targets parameter and use the new
target_buses parameter, translating that into the appropriate list of
devices. This is implemented in this commit for these modes:
-o libvirt
-o local
-o qemu
