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

"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?
If you really mean, "get rid of the z/OS LPAR" then you just give the
OSA to z/VM, set up TCPIP as a controller for a VSWITCH that uses the
OSA, and give every guest a virtual OSA adapter coupled into the
VSWITCH.
If you need to preserve routing to z/OS, then I'd set up an external
network route sending traffic to z/OS via z/VM, and use a physical
HiperSocket with both z/VM and z/OS on it. This introduces another
hop to z/OS.
