Not really sure what can be going on...  The monitor scripts return the 
information of all VMs running in the node.  In 4.6 the
monitoring system uses a push approach,  through UDP,  so you may have the 
information being reported by misbehaved monitoring
daemons.  Sometimes this may happen in dev environments if you are resetting 
the DB,... 

when we ran the update to take this database from ONE4.4 to ONE4.6, one host (the aforementioned fgtest14) and one datastore (image store 101) got wiped out of the database, I reinserted them both back in and restarted opennebula.

      I am currently dealing with an unexplained monitoring question
      in OpenNebula 4.6 on my development cloud.

      I frequently see OpenNebula return that the status of a ONe
      host is "ON" even in the case of a system misconfiguration where,
      given the credentials, it is impossible for opennebula to
      even ssh into the node as oneadmin.


      I've fixed all those instances, restarted OpenNebula,
      but opennebula still reports a number of VM's
      in state "running" even though the node they are running
      on was rebooted three days ago and is running no
      virtual machines whatsoever.

      I think I could be dealing with database corruption of some type
      (generated on the one4.4->one4.6 update), or there could
      be some problem with the remote scripts on the nodes.
      I saw, and I think I fixed, the problems with the database
      corruption (namely one of the hosts and one of the datastores
      got knocked out of the database for reasons unknown, and I
      re-inserted them).   But in any case there is some
      error handling that is not working in the monitoring
      and something is exiting with status 0 that shouldn't be.

      ideas?  Has anyone else seen something like this?
