VirtualBox Example with GNS3

I found the GNS3 setup with Virtual box confusing, as there was no documentation around the network interface setup.

It appears you need to create in GNS3 the Virtual Machine with 2 interfaces and not use the first.

It is then best to disable the first interface on the machine within VirtualBox, so it does not appear in the OS.

The second interface, which is the one which is connected to GNS3 uses (and automatically configures Adapter 2 as a Generic Driver - UDPTunnel“

Here is an outline of the steps involved to add Linux Tinycore to GNS3:

1) Download Linux Tinycore Virtualbox OVA Template from

2) Import Linux Tinycore Appliance
