Hello Steven,
That was a great point. I found the error in the libvirt log for that Vm.
The vnc host was started but on a port that was already listening so the VM
had crashed. Followed by that I recreated the vm-template file with a
different port and its up now. Virsh list shows it up but onevm shows it in
the unknown state . Memory is still 0 .
Followed by that i deployed the ttylinux image as well that comes by
default. Again that shows 0K memory. Unable to figure out the reason.
thanks
Ranjan
