system_reset *resets* the machine (like hitting the reset switch). It
doesn't shutdown anything, probaly not what we want. Here's a patch that
does the ctrl-alt-del (on top of the previous domainsShutdown patch).
This looks much more friendly to the filesystem. There are issues in kvm
where after the reboot the ACPI tables are borked, but that's another
issue.
