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

I am confused about the error in log messages. I just want to have a stable

Kindly help me
Thanks

Using 'virsh create guest.xml' cmds can simply activate the guest, which only
exist active domain instead of define domain,
and the guest will disappear if it isn't in define domain and you carry out
some operations, e.g. 'destroy' or 'shutdown' or
'save' etc. so you should correctly use virsh cmds:
FYI,
virsh -c xen:/// define libvirt-ttylinux.xml
virsh start guestname
