[Xen-devel] Xen + NFS

[jaikumar Ganesh <jaikumarg@xxxxxxxxx>]

Hi All
   We are facing some problems with NFS on Xen:

1. base OS - Fedora core 3.
2. Xen 2.0.7 (installed from src).

/etc/exports file on Domain 0 : / 10.10.10.0/255.255.255.0 (rw,sync,no_root_squash)
NFS has been started.

----------
Config file for guest OSes:

kernel = "/root/xen-2.0/dist/install/boot/vmlinuz-2.6.11-xenU"
disk = ['file:/root/fedora.img,hda1,w']
# Root device for nfs.
root = "/dev/nfs"
# The nfs server.
nfs_server = '10.10.10.1'
# Root directory on the nfs server.
nfs_root   = '/'

Also we have modified the /etc/fstab in fedora.img as below

10.10.10.1:/           
/                      
nfs    
defaults        1 1
none                   
/dev/pts               
devpts  gid=5,mode=620  0 0
none                   
/dev/shm               
tmpfs   defaults        0 0
none                   
/proc                  
proc   
defaults        0 0
none                   
/sys                   
sysfs   defaults        0 0
LABEL=SWAP-hda2        
swap                   
swap   
defaults        0 0

The error we get on loading domain U is :

"Warning : Unable to open console".

We know that we need to set up the initrd for this error, but we used to get this error only while booting dom-0 and not dom-U.

It works fine when we are using file based VBDs and we are able to boot dom-U without any problems.

Any hints?

Thanks
Jaikumar
