SSH access in user mode
-----------------------
Although the IP address of the VM is not visible to the outside, it is possible
to use port forwarding to access the VM's ports from your host, eg the SSH port.
To achieve that:
- In MacOS, turn on SSH under System Preferences > Sharing > Remote Login.
- Modify the startup script to include `-netdev user,id=net0,hostfwd=tcp::10022-:22`
- Use `ssh localhost -p10022` to get in.
You can use the same for VNC.

Using an rc.local startup script

I have the following commands present in `/etc/rc.local`.
#!/usr/bin/env bash
sudo ip tuntap add dev tap0 mode tap
sudo ip link set tap0 up promisc on
sudo ip link set dev virbr0 up
sudo ip link set dev tap0 master virbr0
This has been enough for me so far.
Note: You may need to enable the `rc.local` functionality manually on modern
Ubuntu versions. Check out the [notes](notes.md) included in this repository
for details.
