It might only be that you don't have a VPS physical console, and that
your VPS is fully booted, but you can't see it. There are few things to
check.

First, check that your VPS has a "console" device in /dev. Mount your
domU filesystem in the dom0, go in /dev and do:

/dev/MAKEDEV console

If you are using a modern Xen kernel and hypervisor, you should check
the parameters of the startup file. Check that it has the following option:

extra = "4 TERM=xterm xencons=tty console=tty1"

Then start your VPS and watch it booting. Note that once it's booted up,
you should check that it has a xen friendly libc6 installed (in Debian,
you would do "apt-get install libc6-xen").

I hope that helps.

Thomas
