Guest restarting after issuing a shutdown

[Peter Crowther]

virt-install is expecting the installation process to need a reboot partway
through, so carefully restarts the guest on its first shutdown. Then it
gets out of the way. Either change what virt-install thinks it's installing
(not sure how, never done it), or write and enable a service during
installation that removes itself then shuts down the guest. First install
doesn't run the service, so restarts normally. Next boot starts the
service, which removes itself and forces a shutdown. Job done.

Cheers,

Peter
