New subject: [libvirt] [PATCH 1/2] qemu: migration: Properly parse memory hotplug migration flag
Since the flag was not enabled when 'eating' the migration cookie,
libvirt reported a bogus error when memory hotplug was enabled:
unsupported migration cookie feature memory-hotplug
The error was ignored though due to a bug in the code so it slipped
through testing.

New subject: [libvirt] [PATCH 2/2] qemu: migration: Actually error out on unsupported migration flag
The code reported that a migration flag is unsupported but didn't jump
to the error label. Probably an oversight in commit f88af9dc that
introduced the flag checking.
