Re: [Xen-users] PV domain on NAS

Hi All,

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

# df -h
Filesystem            Size  Used Avail Use% Mounted on
                      131G   80G   45G  65% /
/dev/cciss/c0d0p1      99M   18M   77M  19% /boot
tmpfs                 257M     0  257M   0% /dev/shm
                      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 --rootfs nfs -f /tmp/initrd-nfs1.img 2.6.18-

and use the below as config file.
#cat /etc/xen/para_xen8
vif = [ 'bridge=xenbr0,mac=00:50:56:0b:95:6e' ]
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.

#cat  /mnt2/etc/fstab  /  nfs    rw,bg,intr,hard,timeo=600,wsize=32768,rsize=32768,nfsvers=3,tcp    0 0

none         /proc                proc    defaults        0 0
none         /sys                 sysfs   defaults        0 0

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

Many thanks.
