Fixed the VirtualBox issue now.
Looks like on VB6 you had to add the current user to the vboxsf group.
But on VB7, you have to add them to the vboxusers group instead.

Pixelbook
Spent a big chunk of today preparing for, and attempting to upgrade my Pixelbook to Gallium OS.
I imaged it, then made a file backup of my home directory, before installing the OS, overwriting my Ubuntu, then restoring the home directory backup into the newly installed OS and then chowning the directory to me.
As a habit, I then imaged the laptop at this state.
I prepared a semi-automated script to install apps that I had installed on my Ubuntu, which included things like virt-manager, virtualbox, google-chrome and the like.
However, I soon found out that VirtualBox 6.1 seems to crash the mouse driver on reboot and the mouse pointer no longer moves and Gallium doesn’t even seem to see a pointer device when you check the mouse and touchpad option. I had to revert back to the image just after the file copy.
There is always the option of installing VirtualBox 6.0 from the Ubuntu repositories rather than the Oracle repositories, which uses a different installation setup. Maybe that will result in a different outcome.
Eventually, I restored back to my original Ubuntu installation so I can retry again tomorrow.
EDIT: Retried again the next day, and found out the sound wasn’t working, even on the live disk. Better find out what’s the deal with that…
EDIT2: Found out that my Pixelbook model doesn’t have working sound drivers on GalliumOS. I guess I will have to wait until that is fixed before using that. I guess I’m staying on Ubuntu. In the meantime, I’m going to see if I can compile a later version of the kernel to see if I can somehow get VirtualBox working better.

How Splitting A Computer Into Multiple Realities Can Protect You From Hackers
Virtualisation, Sandboxes, Containers. All terms and technologies used for various reasons. Security is not always the main reason, but considering the details in this article, it is a valid point. It is simple enough to setup a container in your machine. LXC/Linux Containers for example, don’t have as much overhead as a VirtualBox or VMWare virtual machine and can run almost, if not just as fast as a native installation (I’m using LXC for my Docker.io build script), but conceptually, if you use a container, and it is infected with malware, you can drop and rebuild the container, or roll back to a snapshot much more easily than reimaging your machine.
Right now I run three different containers — one is my main Ubuntu Studio, which is not a container, but my core OS. the second is my Docker.io build LXC, which I rebuild everytime I compile (and I now have that tied into Jenkins, so I might put up regular builds somehow), and the final one is a VirtualBox virtual machine that runs Windows 7 so I don’t have to dual boot.

Virtualisation
Wow, you learn something new everyday. I’ve just found out about two variations on virtualisation. Linux Containers (LXC) and Vagrant.
Linux Containers (LXC) is known as OS-level virtualisation, meaning the kernel looks after the virtualisation, and there is no need for some extra management software along the lines of VMWare or Virtualbox. The guest OSes run as containers, similar to chroot jails, and all containers, including the main one you booted from, share the same kernel and resources as your main container. As such, LXC only supports linux-based guest OSes. You can’t (easily, anyway) run Windows under LXC. Homepage, Wikipedia.
Vagrant is a strange one. It sells itself as being a way to keep development environments consistent, and I can understand why — if you have a team of people all with a VM of the same OS, but end with different results because they have tinkered with the settings on the VM OS, Vagrant prevents this by keeping the core one in the cloud, and each time the machine is started up, it checks itself against the cloud version, updating itself if needed. That guarantees consistency. Homepage, Wikipedia.
I haven’t tried both of these tools in great detail yet, but here’s some related links for you to check out:
