Indeed: cookies were added in v0.9.1-148-g8654175, and localHostuuid and
remoteHostuuid were added to the cookie as part of v0.9.1-245-gb336710
(same release of 0.9.2). What version of libvirt are you migrating from
or to where things broke for you?
Oops, this serves as a proof that I actually didn't try it with upstream
libvirt :-( I only tried with old RHEL release, which had pre-upstream support
for migration cookies... I'll send a revert.
