   * What exactly did you do (or not do) that was effective (or
     ineffective)?

from a host running 4.4.1-9+deb8u3 fails every time.

Doing a live migration to a host running Xen 4.4.1-9+deb8u3, 
from a host running 4.4.1-9+deb8u4 works every time.

   * What was the outcome of this action?

A migration to a host with 4.4.1-9+deb8u4 results in this:

~ # xl migrate app01 host01
migration target: Ready to receive domain.
Saving to migration stream new xl format (info 0x0/0x0/1076)
Loading new save file <incoming migration stream> (new xl fmt info
0x0/0x0/1076)
 Savefile contains xl domain config
xc: progress: Reloading memory pages: 53248/1048576    5%
xc: progress: Reloading memory pages: 105472/1048576   10%
<snip>
xc: progress: Reloading memory pages: 996352/1048576   95%
xc: progress: Reloading memory pages: 1048810/1048576  100%
migration target: Transfer complete, requesting permission to start domain.
migration receiver stream contained unexpected data instead of ready message
(command run was: exec ssh host01 xl migrate-receive )
libxl: error: libxl_utils.c:396:libxl_read_exactly: file/stream truncated
reading GO message from migration stream
migration target: Failure, destroying our copy.
migration target: Cleanup OK, granting sender permission to resume.
Migration failed, resuming at sender.

   * What outcome did you expect instead?

~ # xl migrate app01 host02
migration target: Ready to receive domain.
Saving to migration stream new xl format (info 0x0/0x0/1076)
Loading new save file <incoming migration stream> (new xl fmt info
0x0/0x0/1076)
 Savefile contains xl domain config
