Sorry, Ian, I should have looked a little deeper.  The alias is actually 
created;  from whence the error message, I don't know.

Indeed, if I created host alii they are accessable from within the host and guests.  If I 
create alii within the guest they are accessable from within the guest only.  Where would 
I look for an example of "poking an extra vfr rule down"?

I tried using xi_vifinit to assign 10.0.0.32 to eth0:1 on dom1 like this:

        xi_vifinit 1 10.0.0.32 eth0:1

and received no complaints but the guest would no longer boot.

Thanks again,
Mike Wright
