Hello again,
I just realized what the problem was. I didn't specify a 'ramdisk' option in my config file. I told it to use the same initrd as the dom0 and I got a little further in the domU boot, but now I have this error message:
VFS: Can't find ext3 filesystem on dev sda1
Kernel panc - not syncing: Attempted to kill init!
Anyone know how I can fix this?
Thanks a lot

I've finally been able to install Xen (version 3.4 with kernel 2.6.18) and booted the xen kernel. Now I'm trying to create a VM that uses an image file as its disk, but a few seconds after I boot the VM it stops with this message:
[root@localhost xen]# xm create -c xmexample1 vmid=1
No filesystem could mount root, tried:  ext2
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)
Here is the config file:
kernel = "/boot/vmlinuz-"
memory = 400
name = "ExampleDomain"
vcpus = 4
vif = [ 'mac=00:16:3e:00:01:01, bridge=br0' ]
disk = [ 'file:/home/xen/image,sda1,w' ]
root = "/dev/sda1 ro"
extra = "4"
That image, /home/xen/image, was created by a previous Xen installation (it came with my Fedora 7 distro with virt-manager, so I did not have to manage config files. I want to boot from it again using the newest Xen)
