OK: OpenNebula VMs - Total: 32 .. running: 32 .. other: 0
>>>>>> By state
--- Running (runn): 32
The VM is running (note that this stage includes the internal virtualized machine booting and shutting down phases). In this state, the virtualization driver will periodically monitor it.
>>>>>> By host:
--- kvm1.ecample.com: 8
--- kvm2.ecample.com: 6
--- kvm3.ecample.com: 8
--- kvm4.ecample.com: 5
--- kvm5.ecample.com: 5

|total=32;; running=32;; fail=0;; unknown=0;; other=0;; 

If no vm was created yet the result is OK.

/check_onevm
OK: OpenNebula VMs - Total: 0 .. running: 0, Fail: 0, unknown: 0 .. other: 0
