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 people trying to use the VM in the meantime aren't very happy, and reboots take approximately forever if you have a decent amount of guests.
That said, I don't let untrusted users into the host.
