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 On Tue, Mar 29, 2011 at 7:17 PM, Steven Timm <[email protected]> wrote: > If virsh list doesn't show anything that means that the > VM crashed soon after boot on the VM host.
