If virsh list doesn't show anything that means that the
VM crashed soon after boot on the VM host. Look at the libvirt
logs on the VM host. If you have access to virt-manager
or some other way to see a vm console, try to do a onevm restart <vmid>
and see if you can get the console up fast enough to see where it died.

Hello Steven,
Thanks for your quick response.

*3. virsh list doesn't show me any VM that is running on that host. *
Thoughts ?

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

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