"virtual devices"

Hallo,

I just upgraded to version 8.72 and want to use the new "virtual devices" feature.
I already added our ESX3.5 servers to OpManager while still using 8.5. They were listed under servers.

I now moved one of them to the category "virtual devices". But the host and the VMs don't show up there.

I also can't add them there, as they are already in the system.

What is the correct way to move them?

Thanks
Robert
