Thanks Alan you got me thinking.

Here is what I ended up doing.
There is a table in xCAT for mac addresses. What I did was to manually
change that address to match the z/VM assigned address from the NICDEF ..
Then it all worked.

I suppose another, maybe better way would to use the xCAT generated mac
address in the NICDEF statement.

Whatever works..
Tom
