First of all, when doing an install, you can't actually have the
guest reboot at completion. The initial guest configuration for
launching the installer is different, from the configuration for
launching it post-boot. Thus virt-install "fakes" the reboot
by waiting for the guest to exit, and then manually restarts
it.  By when you add  --noautoconsole this won't happen. To
get virt-install to hang around, either remove that option, or
add '--wait'
