IMO, no, unless you anticipate adding more CS Linux servers. > - We could also dedicate an OSA attachment (just 3 unused device > addresses, not the whole OSA) to the userid and let it just run that > connection direct to the OSA and let Linux activate the layer 2 support.

If you share the OSA with other VTAMs, then I think you will have to configure unique SAPADDRs in the XCA major node. And I would guess that, yes, the OSA will fast-path the packet in the adapter, but I don't know fer shur. > - And lastly, since this is MAC address to MAC address, will the default > MAC address VM gives me work, or do I have to build one of my own? For a layer 2 VSWITCH, each guest will get a unique MAC address, so they can all use the same SAP. Since the remote VTAMs/NCPs will want a specific MAC, use NICDEF to assign a static MAC address.
