Re: [one-users] VMM 'unknown' state not being set?
We set the VMM to report :deleted and it went into 'unknown' state, which is perfect for us as we can then issue a VM cancel and it will clean up the VM on the hypervisor as well.

You said you wanted to report the VM is stopped. To OpenNebula that means that the VM disks and the memory state have been saved back to the system datastore, plus the networking is cleaned up, etc. That's something that the VM can't do by itself, so we don't consider the option to report that from the poll info. If by stopped you mean that the VM was shut down, then the drivers can report 'd', and the core will move it to the poweroff state. In any case, a VM in the suspended or poweroff states can be deleted without having to resume it first. At least that's how it works for 4.10, it may be a bit different in 4.6.
