Hi,
I have a computer running OpenNebula 3.8 and two hosts running CentOS
6.3 and KVM. I have one VM running in one of the hosts.
From OpenNebula/Sunstone, I select that VM and then:
* When I press "PowerOff", after a while, the state changes to
"RUNNING" but the VM never shutdowns.
* When I press "Shutdown" the state of the VM changes to "SHUTDOWN"
but the VM continues working (perhaps KVM doesn't support correctly
ACPI signaling). I've connected via ssh to the VM and the executed
"poweroff". The VM successfully switched off but then the VM entry
disappeared from Sunstone. I've checked the existence of the VM in
the host using virsh and it lists nothing.
Eventually, we had to instantiate again the template to recreate the VM.
The image was a persistent one.
This is the log of that VM after pressing Shutdown:

Mon Dec 10 10:23:31 2012 [DiM][I]: New VM state is DONE
As stated in the logs, a "delete" command is executed, so the VM
instance has been erased. This would be an undesirable behaviour for us.
What would be the recommended procedure to shutdown a VM without
deleting that instance in a KVM environment?
Thanks in advance,
Carlos.
