- Download the NetBSD 9.2 release.
- VirtualBox installed and properly setup on your system.
- Setup the installation of the VM as you would any VM installation in Virtual Box.
- Boot into the installation image.
Replicate the steps performed in the following screens. These screenshots skip over simple confirmation pages.
After completing the above steps, you will be asked to perform some manual configuration. You should configure the network, set the appropriate time zone for you, leave root shell as /bin/sh, change the root password, enable installation of binary packages, enable sshd=YES, enable ntpd=YES, run ntpdate at boot=YES, add a user, then click on "Finished Configuring".
Within the VM, we want to open up the /etc/rc.conf file using an available text editor; such as vi. Append the following to the bottom of the file:
sshd=YES
You can now shutdown the VM. Before the next restart, make sure to remove the installation image from the VM's settings.
We are going to run this vm headless then ssh into it. To do so, navigate to the settings page for the NetBSD vm you just installed, then click on the Network tab.
Click on Advanced, then click on Port Forwarding.
The following screen will pop-up. We are going to forward the vm's port 22 to an unused Host port. You should be able to use the port number shown in the following screenshot. Otherwise, fill in an unused port.
In VirtualBox, run the VM as a headless system. Then from your Host system, once the VM has finally booted up, you can SSH into the VM with the following command (assuming you forwarded to the same HOST port as shown in this guide):
ssh -p 3022 <USER>@127.0.0.1
