Thanks Mr. Stefan
Will that crash mainly be due to the kernel ? Since am not sure about that,else I should
try with different image.
When I use via a config file using "xm create libvirt-ttylinux.conf ", then the
domain runs stable....
But when I use the virsh -c xen:/// define libvirt-ttylinux.xml"
and "virsh start ttyimage, it crashes after sometime.
The ibvirt-ttylinux.conf file ::
--------------------------------------------------------------------------------------------------------------------------------
kernel = "/boot/vmlinuz-2.6.18-164.2.1.el5xen"
ramdisk= "/boot/initrd-2.6.18-164.2.1.el5xen.img"
memory = 64
name = "ttylinux"
disk = ['file:/usr/local/ttylinux-xen-libvirt/ttylinux-xen.img,sda1,w']
root = "/dev/sda1 ro"
vif = ['']
--------------------------------------------------------------------------------------------------------------------------------
I give the same Xen kernel parameter here in xml file, and use virsh to create domain
---------------------------------------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<domain type='xen'>
<name>ttyimage</name>

---------------------------------------------------------------------------------------------------------------------------------------
My Boot grub file data::
--------------------------------------------------------------------------------------------------------------------------------------title
Scientific Linux (2.6.18-164.2.1.el5xen)
root (hd0,0)
kernel /xen.gz-2.6.18-164.2.1.el5
module /vmlinuz-2.6.18-164.2.1.el5xen ro root=LABEL=/1 rhgb quiet
module /initrd-2.6.18-164.2.1.el5xen.img
--------------------------------------------------------------------------------------------------------------------------------------
Why is this difference between the xm (when i destroy the image,domain is also destroyed)
and virsh (domain is not destroyed while destroying the image) .
I doubt that am making some mistake with the xml file .... Is that true?
Kindly give some suggestions
Thanks

Hello,
Thanks Alex
I created a domain using "virsh -c xen:/// define libvirt-ttylinux.xml"
and
"virsh start ttyimage" for a simple ttyimage.
Problem I face is that the image shutsdown immedialtely once virsh
start guest is typed.
I checked the Xend Logs

You domain crashed here... Is the VM image and
kernel in that image known to work?
