Perhaps I didn't phrase it correctly.
I have a box installed with os2009.06, as the dom0, running
in hypervisor morde.
I want to install on that box:
multiple domu instances (a mix of both 2008.11, 2009.06,
snv_11x builds etc.) all connected on an internal private
network "in the box".
As I understand it, I need to setup an etherstub for the
'internal ethernet', the appropriate numbers of vnics,
on the dom0 instance, then as I install specific domu
instances using virt-install (for instance using a
2008.11 iso) as a paravirtualized opensolaris instance,
I need to specify one of the vnics (say vnic1) as the nic
to used by the domu, so that the domu talks on the
internal network, instead of the default behavior where
the domu tries to use the physical interface for the box.
I believe that the interface to be specified as a bridge
and the script argument needs to be vif-dedicated...
[I think I read that on one of the teams FAQ's].
e.g. I am trying to do this:
http://blogs.sun.com/droux/entry/private_virtual_networks_for_solaris
with xVM containers versus zones containers.
[So I can run different OS levels/versions] on the same
internal private {NATd] network.
My problem is my experiments on this has configuration issues, and
I am looking for an example set of virt-install steps [or other]
to explain how to set this type of environment up correctly.
Sort of a combination of droux's blog and
http://www.opensolaris.org/os/community/xen/docs/opensolaris_domu/
[that is known to actually work].
Thanks in advance,
Doug.

I know there are crossbow examples of this using zones,
and I have seen xen references saying you need to
do this using a bridge, but I am unable to find a full
example of this setup on-line.
I am trying to setup an environment like this now, but
I am having a connectivity issue, and I have probably missed
a step or two.
I seem to have both a 2009.06 dom0 and domU with
active vnics on an etherstub, that can ping themselves,
but neither can ping or see the other...
Presumably I have something mis-configured.
I am confused. You are mentioning etherstubs. They are intended to be
isolated to the OS instance in which they are installed, as they do not
need, or use, 'external' networking hardware. So VNICs on an etherstub
in one OS instance can not communiate with VNICs on an etherstub in
another OS instance, regardless of what underlying virtualization you
are using.
What I don't know is whether you can extend a VNIC in dom0 to a guest
domU. I don't have xVM (or Xen) capable hardware, so I don't xVM (the
verb :) )

A working example from either team would be appreciated.
Thanks in advance,
Doug.
