[one-users] vm State Issue

[Csom Gyula]

Hi,
to my undertsanding ONE shutdown uses virsh shutdown for KVM VMM [1] . However virsh
shutdown is not guaranteed to succeed. As the virsh man [2] says:

shutdown domain-id
Gracefully shuts down a domain. This coordinates with the domain OS to perform
graceful shutdown, so there is no guarantee that it will succeed, and may take a
variable length of time depending on what services must be shutdown in the domain.

You may check whether your guest OS supports acpi...

Cheers,
Gyula

Tárgy: [one-users] vm State Issue

Hi,
    I am using opennebula 1.4. I used Ubuntu 10.04 for all node (front node/worker node) .
I Deployed opennebula with few worker node with kvm hyperwiser.
There is lot of confusion about vm states.

When i shutdown or suspend the vm from front node, it show the status
"shutdown / save / suspend" at front node.
But if i check on worker node with virsh or virt-manager, it shows the vm status
running.

I am not able to change vm state by any way from front node.
I just want to know that It's default behavior or I did something wrong with
opennebula configuration.

There was same problem with 1.2.
I Migrated to 1.4 with the hope that the problem will get solved with version 1.4.
So , kindly reply for the solution of problem.
