I suggest you use virt-rescue.  It's a lot easier than messing around
with boot CD configuration.


virt-rescue contains some common partitioning tools already, and you
can attach a second disk containing any other (Linux) tools you need.

The monitor is explicitly *not* available from libvirt.  It would be a
huge security hole for us to allow any user to just switch over to the
monitor and start typing any monitor commands.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
