[xenpreview-dev] SUSE Xen 9762 live migration tests

[John Byrne]

I ran a "ping-pong" live migration test on x86-64 of a 3GB UP guest 
domain running kernel makes over the weekend. (I was using a shared disk 
for the storage.) 2664 migrations (the script had a 2 minute pause 
between migrations): no hangs, no panics, no obvious errors to be found 
in the output from the make. fsck found no corruptions on the disk.

So things look pretty good with a shared disk. I don't think the issues 
related to using file-backed vbds for migration have been resolved yet, 
so I am not going to test that at the moment.
