Automated generation of Xen VMs

This stuff is still a bit rough at the edges, it will take a bit more effort to put it in an RPM package. So until that time, here's the recipe to configure it manually.

Draw the scripts from [the VLeForge CVS repository]. They will need some tailoring.

You need the following other stuff:

• Apache web server
• Xen DomU installation kernels
• LVM volume group with plenty of free space
• plenty of free space in /var/local/xen
• NFS server

Preparation

Create the directories

/var/local/xen
/var/local/hostkeys

The former will have almost all the stuff we need, the latter will have ssh host keys (possibly also SSL certs+keys)
