[Xen-users] XEN : Getting Error: (22, 'Invalid argument') on starting guest domain.

["Arun Sharma" <arunain@xxxxxxxxx>]

Hello All.

Below is the error i am getting while starting the guest domain.Not sure whats the issue. The only thing i know is , it may be becuase of kernel mistamath with 32bit PAE or NON-PAE support. But this is not the case with me since i am using 64bit processor and downloaded the proper tar ball from xensource website. I have given the link below also.

[root@arpc2 ~]# xm create -c /etc/xen/centosvmgui.conf 
Using config file "/etc/xen/centosvmgui.conf".
Error: (22, 'Invalid argument')

Other information

I am running CENTOS 5 , with AMD Athlon 64 Bit 4800.

I have downloaded 64 bit 
XEN3.1 tarball from http://bits.xensource.com/oss-xen/release/3.1.0/bin.tgz/xen-3.1.0-install-x86_64.tgz

All installation went well with grub configuration. 

XEN dom0  is working like a champ with no issues.

My /etc/xen/centosvmgui.conf 

--------------------
kernel='/boot/vmlinuz-2.6.18-xen'       #The kernel to be used to boot domU
ramdisk='/boot/initrd-
2.6.18-xen.img'   #Need the initrd for ramdisk
memory  = 256                           #Memory allocation
name    = 'centosvmgui'                 #Machine name
cpus = ""                                       # Specific CPU's to assign the vm, leave blank
vcpus = 1                                       # Number of available CPU's to the system
vif = [ '' ]                                    # Defines the virtual network interface

# File based VBD
disk = [ 'file:/mnt/LogVol00/centosvmgui.img,hda1,w']   # Guest storage device mapping to the virtual machine

root = 'ro /dev/hda1'                           # Root partition kernel parameter

------------------------

My /boot directory contains below files.
