Doh, brain fart VDSM is not involved here for the purposed of the needed
test.
Here is my initial whack at it:

Shu,
I build oVirt Engine and vdsm from source myself. The commits I indicated
are what I built from.I run the engine under FC17 and my nodes are running
EL6.x respectively.
Dan,
I reverted VDSM on my two test nodes to an earlier build of VDSM (commit:
c343e1833f7b6e5428dd90f14f7807dca1baa0b4)
VDSM after the above commit is broken due to commit:
fc3a44f71d2ef202cff18d7203b9e4165b546621 however when I built and tested
from master yesterday I did apply a patch I tested for
ybronhei which fixed that issue.
I will build VDSM from master, today w/ the supervdsm patch and try the
manual migration you indicated.
