When trying to auto deploy virtual appliance (VA) from wizzard there are no ESX hosts or clusters available for selection.
This is seen when you have your hosts and/or clusters in folders within your virtual center.
There are two work-arounds for this issue:
1. remove host or cluster from folder from within VC and run auto deploy.
2. manually deploy VA. Then go to tools >> options >> virtual applicance configuration >> add.
From this view objects in folders are viewable.
In this example the virtual center has a single stand alone host and 2 clusters. The single stand alone host in in the folder and is not visible in the vRanger VA auto deployment wizzard.
