LiSA can act like VDE2 ??!! I mean, can I create a virtual uplink through ssh, for examplo?!

Just like the following diagram:

Look that "CrossCable"! Is that what I always want to do... but I don't know how to connect my domU with the VDE2...   :-/

I'm writing on behalf of the LiSA Project team (http://lisa.ines.ro/).
LiSA is an open-source project that aims at building an intelligent
network switch on top of linux.

One of the applications that we find most interesting is using it
instead of traditional linux-bridge to deliver network connectivity to
xen guests. The advantages of LiSA over linux-bridge module are:

* built-in support for vlans (802.1q);
* minimum packet copy/change optimizations for broadcast/multicast (when
several tagged/untagged ports are involved)
* enhanced CLI for configuration/management of the switching engine (the
CLI is very similar to the Cisco IOS)

We've managed to integrate LiSA with xen (with respect to both xen
networking scripts and xen's tcp/udp sum offload optimizations).

Pre-built packages of the latest LiSA version for Centos 5 / i686 are
available at:

Source code is available through the following git trees:

and a git web interface is also available. For further details, see
http://lisa.ines.ro/ - the "Git Repositories" section.

Any feedback is welcome.
