[Xen-users] DomU image file on NFS Storage

[Antonio Colin <dftonywhite@xxxxxxxxxxx>]

Hi everyone,

I have created a CentOS4 PV on a Xen host contained in a *.img file. Now I want to store that image file

on a NFS server. Does anyone have a config.sxp file example and want to share it on a pastebin service?

I have put the *.img on an NFS server, then mounted the img using #mount -o loop image.img /mnt/centos

and then exported it to the xen host but it does not work since the DomU kernel does not have Root NFS support.

How can I do instead to read directly from the xen host the *.img file stored in the NFS server, I think it would

look like: nfs_root = "/mnt/images/centos/image.img".

** This does not work at all, it ends up with a kernel panic on console.

kernel = "/mnt/images/centos/boot/vmlinuz-2.6.9-89.ELxenU"

ramdisk = "/mnt/images/centos/boot/initrd-2.6.9-89.ELxenU.img"

memory = 512

name = "centos4"

vcpus = 1

vif = ['']

dhcp = "dhcp"

ip = "192.168.1.100"

netmask  = "255.255.255.0"

gateway  = "192.168.1.254"

hostname = "centos4"

nfs_root = "/mnt/images/centos/"

nfs_server = "192.168.1.98"

root = "/dev/root"

on_reboot   = 'restart'

on_crash    = 'restart'

I would really appreciate one example or config option.

Regards,

Tony.
