Well look at it this day, this is either a
crappy day for you, or your lucky day, depending on how good my documentation
was. I’m still very new with Xen, but I have been messing around with several different
setups, and the most recent one is exactly what you just said you needed, a FC4
domU on a FC5 dom0.
And with luck, that’s the one that I used to document the entire
process so I could easily refer back to it later.
http://mitopia.net/index.php/Xen_3.0.2_Setup
It’s not much of a site, literally
my own notes that I made for myself, but hopefully you’ll be able to make
sense out of it too.
Also I noted in here how I got NAT to work
through Xen. I
was going to post this in reply to a few NAT related questions once I’m
sure I have all the bugs worked out of that, I’m still messing with the
firewall rules. The entire Xen setup is working perfectly though.
If anyone else who knows what
they’re doing with Xen could look through it
and maybe give a few pointers or corrections that would be cool too.

Subject: [Xen-users] FC4 domU on
FC5
Hi all. This has been mentioned once before on this list, with no
resolution that I could find. I'm trying to make a domU with FC4 running
under a FC5 dom0. Following the instructions located at http://www.fedoraproject.org/wiki/FedoraXenQuickstart ,
xen produces these errors:
[root@localhost xen]# xm create -c cpanel
Using config file "cpanel".
Error: Error creating domain: (22, 'Invalid argument')
[root@localhost xen]#
And from /var/log/xend.log:

This is my conf file /etc/xen/cpanel :
[root@localhost
xen]# cat /etc/xen/cpanel
kernel ="/boot/vmlinuz-2.6.11-1.1369_FC4xenU"
memory = 196
name = "cpanel"
disk = ['file:/root/cpanel.img,sda1,w']
root = "/dev/sda1"
extra = "ro selinux=0 3"
[root@localhost
xen]#
I have
tried this with both the kernel mentioned above, as well as the latest 2.6.13
kernel for FC4xenU. Any suggestions would be appreciated.
