[vbox-dev] [PATCH] UDPTunnel : new network interface backend to allow using this to link to GNS3 and QEMU instances over the network

[Alexey Eromenko]

A letter to community:

UDP Tunnel networking
---------------------

UDP tunnel is a great mechanism to interconnect virtual machines
running on different hosts. It is intended for advanced users.

Technically this is done by encapsulating guest's ethernet frames into
host's UDP/IP packets, and sending them to the destination. This
tunnel is a sort of VPN, except that UDP tunnel is not encrypted.

----------------------------

This feature will enable GNS3 network simulator to work perfectly
together with VirtualBox.
GNS3 allows to build clouds and distributed network topologies in very
nice graphical way, where you can actually *draw* network topology,
and interconnect VMs together, even if they run on different physical
hosts. GNS3 is very user friendly.

So you all are encouraged to test UDP tunnels, and report your findings.

Best wishes,
