In response to my own post, I noticed the parameters for 'vif' in the
config file match up to those for vif-bridge... except for the 'ip'
parameter.  Would something like this in the domain configuration file
make sense?

vif = [ 'ip="192.168.1.80/32"' ]

or to better follow the example, even this:

vif = [ 'mac=aa:00:00:00:00:11, bridge=xen-br0, ip="192.168.1.80/32"' ]

Of course, no scripts see ip as a valid argument so it doesn't work
now... it returns something like "Error: Invalid vif specifier:
ip=192.168.1.80/32".  Interestingly enough i've tried modifying
create.py (in the build tree so it builds create.pyc) to include 'ip' as
valid, same error.  Then I completely commented the 2 lines of code that
check and return the error and it STILL does it so i'm obviously missing
something, I guess I just need either a pointer from someone or to bury
myself in the code for a little bit more.
