This looks to be recurring, so I've taken another look. The three
migrations leave this abbreviated pattern in the log:
Sep 3 14:20:42.446667 (XEN) HVM d1v0 save: CPU_MSR
...
Sep 3 14:20:57.850670 (XEN) HVM2 restore: CPU 0
...
Sep 3 14:21:37.062840 (XEN) HVM d2v0 save: CPU_MSR
Sep 3 14:21:37.062888 (XEN) HVM3 restore: CPU 0
...
Sep 3 14:21:56.438552 (XEN) HVM d3v0 save: CPU_MSR
...
Sep 3 14:22:11.506508 (XEN) HVM4 restore: CPU 0
Therefore I wonder whether the first one got lucky and finished
barely ahead of timing out, while the 2nd worked instantly and the
3rd then ended up exceeding the timeout. What is curious are the
intermediate log entries (between the last "save" and the first
corresponding "restore" log entries): Many ones of the form
(XEN) emul-priv-op.c:1113:d0v2 Domain attempted WRMSR c0011020 from 0x0000000000000000 to 0x0040000000000000
with a 15s gap between the first and many subsequent ones) and
finally one of the form
[ 451.267669] systemd-logind[2766]: New session 39 of user root.
And finally, at around the time of the failed migration
INIT: Id "T0" respawning too fast: disabled for 5 minutes
While it's not clear that this parallel activity is causing the
migration to progress too slowly, it looks to be a possibility at
least. Can anyone explain what these are?

I take it that this is supposed to be taken care of by a342900d48
("tools/shim: Apply more duct tape to the linkfarm logic").
