There is attribute called "pae-VmState" in ADAM database which is set to "Ready" value, when recompose or refresh operation call is finished. But VM could get some startup related problems. Since everything should be stored in ADAM database, is there any attribute which defines "Available" state seen in View Manager -> Inventory -> Status ?
Or can you suggest any other method for checking VM availability? What do you think about pinging each virtual machine and checking if View Agent service is up & running?
