Xen, booting up issue



Hi

I've got the following problem when running xen on fedora core 4 Test 1 using, xm create -c rawhide:

VFS: Cannot open root device "mapper/VolGroup00-LogVol00" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)


Can anyone please help with this? I've tried mapping different device nodes, but I can't narrow down the problem, my mount looks like this:

/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
/dev/proc on /proc type proc (rw)
/dev/sys on /sys type sysfs (rw)
/dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda1 on /boot type ext3 (rw)
/dev/shm on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

My xen domain file (/etc/xen/rawhide) looks like this

kernel ="/boot/vmlinuz-2.6.11-1.1225_FC4xenU"
memory = 100
name = "rawhide"
nics = 1
disk = ['file:/root/fedora.img,mapper,w']
root = "/dev/mapper/VolGroup00-LogVol00 ro"



Any help will be greatly appreciated.

Many Thanks
Shaz
