I'm not sure I understand the entire issue, but my MVS sysprog has an interesting idea. I showed him VSWITCH article by Mark & Bruce in the Sept 2004 z/Journan mag but I'm not clear what to do myself.
"Right now I have a Z/OS lpar that is managing a OSA express card that is attached to our lan network. This lpar routes packets to the hipersocket network which z/vm and the linux systems are a part off. I would like to eliminate that Z/OS lpar and run the OSA express from Z/VM. I looked at the tcpip manuals for the V4.4 we have and it does not mention the parms required to do the routing. I do not know if a V5 Z/VM would be able to handle it. It was that IQDIORouting of the IPCONFIG statement I showed you. I read some of the books on the vswitch you mentioned but I am not sure how it works or if it would be better than the hipersocket approach." Any suggestions? Thanks, Bob Heerdink
