VirtualBox Errors trying to run ChromeOS [Solved]

[Faraclas]

I'm trying to run Chrome OS as a guest in virtual box. For the ChromeOS I am using Camd64OS-2015 0126010102.vdi

I have setup VirtualBox to use Other Linux 64-bit

When starting the virtual machine, I get the errors (included in a screenshot: https://drive.google.com/file/d/0Bx3sv-qzs46odmVYRGkycXRnOG8/view?usp=sharing):

* couldn't mount as ext3 due to feature incompatibility
* SMBus base address unititialized - upgrade BIOS or use force_addr=0xaddr

* Edit
When I first posted this, I thought it was a problem with my gentoo system and/or installation of virtual box. Now I think it is a problem with the Chromium OS builds and as such does not really belong here.
