Add-ons for Chrome OS + VirtualBox

Question

I cannot install VirtualBox guest add-ons in the latest version of Google Chrome OS. When I run the installer, I get the following error:

  Verifying archive integrity ... All good.
 Uncompressing VirtualBox 4.1.8 Guest Additions for Linux .........
 VirtualBox Guest Additions installer
 mkdir: cannot create directory `/opt/VBoxGuestAdditions-4.1.8 ': Read-only file system
 tar: /opt/VBoxGuestAdditions-4.1.8: Cannot chdir: No such file or directory
 tar: Error is not recoverable: exiting now

What should I do now? Can I mount a file system in read-write mode? Does Lime support guest add-ons? I am using the Vanilla build.

Operating System: Mac OS X Lion (10.7)
Guest OS: Google Chrome OS Vanilla from http://chromeos.hexxeh.net/
VirtualBox Version: 4.1.8

Answer 1

So, someone from the VirtualBox IRC channel irc: //chat.freenode.net/#vbox told me that guest add-ons will not work on Chrome OS.

Having tried the offer from @sarnold, running mount -oremount,rw / , I was told

  Unable to determine your Linux distribution 

Answer 2

If you want to try re-sorting the file system as read-write, the command:

 mount -oremount,rw / 

But there may be a good reason for / be set read-only. I doubt that VirtualBox guest tools take care of where they are installed, so if you just unzip the archive using tar or ar or something else, you can probably install them somewhere where the read-write is mounted and Customize them accordingly.

If you don't mind using dev mode, I was able to run parrot os vm with qemu and kvm on a pixelbook. I used the script for changing kernel flags from the crouton repository, then installed the qemu and kvm packages for my usual crouton boot in crouton. The Virt manager does not work, but I can create a hard disk image from the CLI and boot the VM from the CLI, and it all works, although it is a bit slow, even with KVM. Probably the reason is that even a pixelbook has fewer resources compared to a regular laptop.
