[Xen-users] NFS root in domU

[Maxim Rozin <maxim@xxxxxxxxxxxxxxxxxx>]

Hi there,

I'm using xen-3.0.2.2-86.1_rhel4.1 on a Redhat AS 4 update 1 for i386.
When I try to create domU with NFS root, I get the following error:
##BEGINNING##
Red Hat nash version 4.2.1.3 starting
Mounted /proc filesystem
Mounting sysfs
Creating /dev
Starting udev
Loading scsi_mod.ko module
scsi_mod: no version for "struct_module" found: kernel tainted.

mount: error 2 mounting none
Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2

##END##

My vm conf file looks like this:
##BEGINNING##
kernel = "/boot/vmlinuz-2.6.16-xen3_86.1_rhel4.1"
ramdisk = "/boot/initrd-2.6.16-xen3_86.1_rhel4.1.img"
builder='linux'
memory = 256
name = "nfsvm"
vcpus = 4
vif = [ 'bridge=xenbr0' ]
dhcp="dhcp"
hostname= "nfsvm"
root = '/dev/nfs'
nfs_server = '192.168.1.123'
nfs_root   = '/diskless/i386/RHEL4-AS/root'
extra = "3"
##END##

Please help,
Maxim.
