The area of virtualization saw quite a few enhancements with version 12.2. There's one particular virtualization enhancement that can make a big difference for a lot of people: support for brownfield Oracle VM Servers for SPARC.
Brownfield refers to Oracle VM Servers for SPARC that were created outside of Ops Center. In older versions of Ops Center, you couldn't really do anything with them - Ops Center could only manage OVM Servers that it created. If you had OVM Servers outside of Ops Center, you'd have to recreate them if you wanted to manage them.
In 12.2, though, this problem is cleared up. You can discover and manage OVM Servers for SPARC that you created outside of Ops Center, so long as the LDom Manager is running. When you discover the control domain,
all of the logical domains are automatically discovered and
managed and appear under the control domain in the Asset tree.
If you want to use server pools and migrate the logical domains to
a different Oracle VM Server for SPARC system, you'll need to move
the metadata to a shared library and use shared Fibre Channel or
iSCSI LUNs for the guest domain storage and add the server to a
