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)
