Improve Unkown State Management
|Assignee:||Ruben S. Montero||% Done:|

|Affected Versions:||OpenNebula 3.4|
Currently if a machine is shutdown from within the machine (e.g. via halt), the VM lands eventually in the "unknown" state in OpenNebula. It would be more useful if some more descriptive tag were used for this, such as "halted". This would also help distinguish normal situations from abnormal ones. The virt-manager show machines halted internally as "stopped", so it appears that this information is available from libvirt.

I just started a VM using OpenNebula and run halt from the VM.
"virsh list --all" gives me nothing. How do I find the same information virt-manager has as you described.
In fact, I opened up my virt-manager and couldn't see anything.
Maybe it only has the information if the VM is started/shutdown by virt-manager?

It would also be good if CPU and memory allocations would be marked as free when a VM is in this state. E.g. I have very limited computing resources here and my users tend to use the VM internal shutdown rather than Stop when they don't need the VM. This leaves me with cloud nodes appearing as fully allocated in OpenNebula while in reality they don't have any work.

Since 4.0 we have a couple more states like poweroff that may help with this. Also unknown state is better handled when a VM is restarted from unknown, finally the VM probes should be now capable of moving the VM to the right state (if not really unknown).
I think is better not to free resources until the VM is actually removed from the host.
