[Xen-users] NFS Boot

[Abhishek Gaurav <gaurav@xxxxxxxxxxxxxxxx>]

Hi,
I am new to xen and am trying to boot a VM from an NFS server. I am 
using the default FC6-xen kernel and I do not have a /dev/nfs in dom0. 
My config file is :
kernel = "/boot/vmlinuz-2.6.18-1.2798.fc6xen"
name = "test8"
memory = "512"
uuid = "2cc550ec-550a-6ad2-8121-7b089fc7d051"
vcpus=1
root = '/dev/nfs'
nfs_server = 'xx.xx.xx.xx'
nfs_root = '/home/xen-images/fc4'

I run into the following problem during boot:

TCP bic registered
Initializing IPsec netlink socket
NET: Registered protocol family 1
NET: Registered protocol family 17
XENBUS: Device with no driver: device/vif/0
md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.
VFS: Cannot open root device "nfs" or unknown-block(0,255)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(0,255)
Please let me know what is that I am doing wrong.

Thanks,
Abhishek.
