Congrats Lionel! Glad to hear your joining us. Well, guest LANs can be easily picked up and moved to a whole new system and the Linuxes don't have to get new IP's. That's one thing to consider. But VSWITCHes have other advantages.
Assuming both ports on that OSA card are yours, attach them to different subnets/switches. Use a VIPA address for your VM stack with interfaces on both ports and use MPROUTE for dynamic routing there. Gen your OSA with as many addresses as possible in case you want to change things later. Oh, I was told to request a whole subnet for the OSA interface by the folks here in the know. Marcy Cortes "This message may contain confidential and/or privileged information.

You get the best of both worlds, all of the guests connect to an internal LAN service and they all look like they are on the same network as z/VM.
