Re: [Xen-users] PV domain on NAS

["trilok nuwal" <tc.nuwal@xxxxxxxxx>]

Hi All,

I am polulating root filesystem of domU form the dom0 ( RHEL5 ) itself.

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                     
131G   80G   45G  65% /
/dev/cciss/c0d0p1      99M   18M   77M  19% /boot
tmpfs                
257M     0  257M   0% /dev/shm
/xen-tool/para_xen8/para_xen8-root
                     
5.8G  4.8G  702M  88% /mnt2

I exported the /mnt2 as nfs location.

# cat /etc/exports
/mnt2 *(rw,sync,no_root_squash)

# ls /mnt2
bin  dev  etc  home  lib  lib64 
poweroff  proc  root  sbin  selinux  sys 
tmp  usr  var

Now i created the initrd image using below command.
#mkinitrd -v --rootdev 139.185.48.195:/mnt2 --rootfs nfs -f /tmp/initrd-nfs1.img 2.6.18-8.1.6.0.6.el5xen

and use the below as config file.
#cat /etc/xen/para_xen8
kernel="/boot/vmlinuz-2.6.18-8.1.6.0.6.el5xen"
ramdisk="/tmp/initrd-nfs1.img"
memory=512
vcpus=8
name="para_xen8"
vif = [ 'bridge=xenbr0,mac=00:50:56:0b:95:6e' ]
root='/dev/nfs'
nfs_server='139.185.48.195'
nfs_root='/mnt2/'
dhcp="dhcp"
extra="3 selinux=0"

When i create the domain it starts well but stuck in between the starting of user applications.

looks like it couldnot find the commands used in the application.

Can anybody point out where thing could be wrong ?
Is it anythg wrong in creating the initrd image for nfs root filesystem ?

Many thanks.
