My config is:

kernel ="/boot/vmlinuz-2.6.11-1.1369_FC4xen0"

I'd suggest using the xenU kernel (it's in a different RPM) unless you are planning on granting access to hardware to the domU.

memory = 400
name = "rhel-3-es"
nics = 1
disk = ['phy:cciss/c0d0p2,sda1,w']
root = "/dev/sda1 ro

and my /etc/fstab in the domu is:

/dev/sda1                /                       ext3    defaults        1 1
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /proc                   proc    defaults        0 0
none                    /dev/shm                tmpfs   defaults        0 0
/dev/cciss/c0d0p6       swap                    swap    defaults        0 0

Secondary issue - I doubt that swap line will work.
