Not sure if this is expected or not.
I think Ian saw this with the 'fast-cancel' something resume but I might be incorrect. Did it work if you used xend (you might have to configure it be enabled)?
I have not used xend/xe in a long time. I did need to configure it.
Does not start:
# /etc/init.d/xend start

How important is it to try this?
It tells us whether the issue is indeed with the 'fast-cancel' thing.
But, I do recall seeing a patch from Ian Jackson for this - I just
don't remember what it was called - it was posted here and perhaps
applying it would help?
I have not found a patch. The bug #30:
http://bugs.xenproject.org/xen/bug/30
Looks to me like the issue I am seeing. The Guest I was testing
this on is an old kernel (as far as this bug) and so I would
expect it might be related.
Here is what I see that may link it to this:
So I will continue the fight to get xend running.

Ah, now have xend running, but still need to convert from an xl.cfg
file to a xmdomain.cfg... Having not used xm in years, this will
take a while. The man page does not say how to build an hvm guest.
I did another test and Fedora 19 (x86_64) saved just fine. So this
looks to be bug #30.
If I understand this all, this means that the older linux kernels
will fail this way also if a migrate fails and the source guest is
restarted.
So, do I continue to get xend working, or just say it is an example
of bug #30?
