Uhh, actually I find virtualization makes rebooting the host easier. My
server is running CentOS 5 with its previous Debian install running in a
Xen VM, that still handles most of the services. Apparently when the
host reboots, the VM is automatically hibernated, and restored on the
next boot. The VM hardly notices anything happened at all, just a
temporary lack of network connection and CPU time... :)

The more disruptive thing is, doesn't everyone's *VM*s need to be
patched and rebooted now too? :P
