[Fedora-infrastructure-list] Xen Server and Network Tracking

Xen Server and Network Tracking
===============================
http://fedoraproject.org/wiki/InfrastructurePrivate/PhoenixServers/XenSer...
Please track Xen guests and network assignments on this page.

Template Installed
==================
I have a template xen guest installed with yesterday's rawhide on 
/dev/mapper/VolGroup00-template of xen1.  The template has its 
networking disabled.  If you copy the template to create another guest, 
get an IP address assigned, then add it to 
/etc/sysconfig/network-scripts/ifcfg-eth0 before enabling it.

Although I am not sure how useful it is to use this template, given that 
you can use anaconda to install a new xen guest within minutes.

Any ideas of the best way to make an image file of this LVM volume so 
that we can easily copy it to the xen2 server?

dd would be my best guess.

I don't think we really need a
template.  What i think would be better is a 
script  that we pass  a few paramaters to and creates a lvm volume and gets 
the install started.

I guess we could  pass to the script the guest name, the size of the logical 
volume and the distro to install we could  keep in in hardcoded things like 
ram (512mb  probably sane  can be changed later)  and the paths to the 
distros to install. 

and  have an optional kickstart config path

Yeah I'd have to agree with this in an LVM environment.  I'd always
used templates but I also typically use xen with actual files on the
filesystem.  On second thought it may not work as well with a LVM
setup :(

I'm removing the template because it is quick and easy enough to do a 
regular xenguest-install.  Plus, we should be testing the installer 
often anyway. =)

I'm adding more details and HOWTO's here too.
