          By default this assigns vsock numbers starting at 3 to the nodes.

          On e.g. large builders used by multiple people, this would cause conflicts

          between multiple users doing interactive debugging.

          This field is only relevant when multiple users run the (interactive) 

          driver outside the sandbox and with the SSH backdoor activated.

          The typical symptom for this being a problem are error messages like this:

          `vhost-vsock: unable to set guest cid: Address already in use`



          This option allows to assign an offset to each vsock number to

          resolve this.
