I've seen this phenomenology on an earlier version of xen than
I am using today. Upgrading to 3.0.4 made things work better, but
not yet 100% reliable. Suggest you try "service xend restart" on
machine 2 before the migration and see if you get different results.

FYI, the Xen developers are not yet advertising migration as a stable
feature. I.e., as a migration user you are inside their development
cycle ("helping them debug").

Caveat emptor,

Joe.
