RE: [Xen-users] DomU image file on NFS Storage

[Antonio Colin <dftonywhite@xxxxxxxxxxx>]

Hi,

Yes, but I think that is only for Xen Server isn't it? I am using Xen hypervisor 4.0.0 + Debian Lenny as Dom0. 

Is there a way to achieve NFS SR on Xen 4 ?? I have been looing for that on Google but nothing yet.

Thank you in advance,

Tony.

In Xen, you need to create a Storage Repository for the NFS share instead of trying to manually make the connection to the NFS share.  Then Xen will be able to use the NFS share for storing DomU images.

Subject: [Xen-users] DomU image file on NFS Storage

 

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.
