This is because the domains crashed and then were restarted.
In the domain config file (in /etc/xen), the default is:
on_crash = restart
You can set on_crash = preserve to prevent the domains from
being restarted after they crash.

I have seen this error previously on my system. After making sure that
the domain config file is correct(several options have been changed),
and doing a 'make mrproper' before rebuilding Xen stuff, this error
went away (at least on my system).
