Folks, One of the major new features enabled by the latest Crossbow snapshot we released earlier today is the ability to create completely virtual networks through the creation of "etherstubs" (previously refered to as as "anchor VNICs" on this list.)
In order to illustrate these concepts, I just published a blog entry which shows how etherstubs can be used to create a private virtual networks of zones communicating with the physical network via NAT running in the global zone on the same machine. The same mechanism also applies to xVM server x64 virtual machines since xVM uses Crossbow for its network virtualization. You can find the entry here: http://blogs.sun.com/droux/entry/private_virtual_networks_for_solaris More details about the Crossbow virtualization architecture can be found in the following document: http://opensolaris.org/os/project/crossbow/Docs/crossbow-virt.pdf Enjoy!
