I haven't found the need to reboot my xen servers for any reason other
than security updates.

One had an uptime over 6 months (until a datacenter operator hit the
power button on my server by mistake) and another one has been up for
similar times.

The only problem I have had was on a test machine - once the domain id
got up to 2000 or so (very frequent stopping and starting of domains to
test migrations etc) it seemed to run out of resources. I haven't seen
that with 3.3.x though.
