On the other hand...

On my victim JS21, eth0 is the default, and xen scripts work as written.
However, in this case, DomU accesses the 9.2x network, rather than 192.x

Right - I was thinking of DomU access to only 192.x.
For machines on 192.x to access 9.x, you need forwarding...

We have several JS21, all with two ethernet interfaces, both interfaces
in use.For example this is what things look like when we boot one
such blade with the latest xen and linux for xen and before starting xend.
