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)

Apache

You want to serve /var/local/xen, so add

<Directory /var/local/xen>
        Options Indexes FollowSymLinks
        AllowOverride None
</Directory>
Alias /xen /var/local/xen

to your Apache configuration (e.g. /etc/httpd/conf.d/xen.conf)

NFS

To distribute keys to hosts, make the xen and key directories NFS mountable. Add this line to /etc/exports.

/var/local/xen 10.0.0.0/8(ro,async,no_root_squash,insecure)
/var/local/hostkeys 10.0.0.0/8(ro,async,no_root_squash,insecure)
