Hello Steven,<br><br>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 . <br>
<br>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. <br><br>thanks<br><br>Ranjan<br><br><br><br><div class="gmail_quote">On Tue, Mar 29, 2011 at 7:17 PM, Steven Timm <span dir="ltr"><<a href="mailto:timm@fnal.gov">timm@fnal.gov</a>></span> wrote:<br>

VM crashed soon after boot on the VM host. Look at the libvirt<br>
logs on the VM host. If you have access to virt-manager<br>
or some other way to see a vm console, try to do a onevm restart <vmid><br>
and see if you can get the console up fast enough to see where it died.<div><div></div><div class="h5"><br>

Look at your oned.log and at the nnn.log which is the log of<br>
the virtual machine number in question. Probably it first shows zero<br>
and then goes to unknown because something is failing in<br>
one of the monitoring scripts so it can't monitor. The logs should say.<br>
<br>
Did you note which host the VM is running on? does virsh list on<br>
that host show that it is still running?<br>

There is enough Ram on my machine but somehow apart from the default<br>
"ttylinux" image, any other image I create with memory value specified in<br>
the *vm-template.one* file results in generating the VM but the memory<br>
column always shows 0K. After a while , the VM goes from running to<br>
unknown<br>
. I can't see any error message . This is on Centos 5.5 and I am using kvm<br>
as the hypervisor.<br>
<br>
onevm list<br>
<br>
22 oneadmin ttylinux runn 0 64M <a href="http://machine.th" target="_blank">machine.th</a> 05 01:56:35<br>
56 oneadmin vm *runn *0 *0K* <a href="http://machine.th" target="_blank">machine.th</a> 00 00:00:56<br>
<br>
Any suggestions ?<br>
<br>
thanks<br>
