The only people who can migrate a domain in any sensible deployment
would be host administrator or maybe the VM admin. So there is no
security aspect since they already more than privileged enough to simply
destroy the domain if they wanted.

The status of xl in 4.1 was "try it and if it works for you great,
otherwise stick with xm". This particular issue is already fixed in
newer Xen, which is good.

FWIW this was fixed by git commit 062ef262f9df upstream. Looks like it
was fixed in 4.2-rc1.
