Re: [Xen-users] Unable to deploy a VM on xen 3.0.3

["Omer Khalid" <Omer.Khalid@xxxxxxx>]

First of all thanks of all of you for your help and advices, especially to mention Zhang Binbin and Mats Peterssons.

Status: Still not working!

Whats tried so far: 
* selinux disabled for both dom0 and domU
* added "root='/dev/sda1 ro'" to xen config file. Also tried with xvd1 and hd1 in place of sd1.
* created initrd for domU

To recap, here is my 

=== xen config file ===
name = "slc4xern"
hostname="M-Ctb-Generic-5"
kernel="/boot/vmlinuz-2.6.18-1.2835.slc4xen"
ramdisk="/boot/initrd-2.6.16-xen.img"
memory = 512
#vcpus = 2
disk = ['phy:vg1/slc4xernroot,sda1,w','phy:vg1/slc4xernswap,sda2,w' ]
root= "/dev/sda1 ro"
vif = [ '' ]
ip= "128.xxx.xxx.xxx"
gateway="128.xxx.1.1"
#bootloader="/usr/bin/pygrub"
on_reboot   = 'restart'
on_crash    = 'restart'


=== end of config file ===

When I try to start the domain by "xm create slc4xern -c", the output is the following:

=== domU console output ===
Using config file "/etc/xen/slc4xern".
