I've been wracking the net for several days on this topic. i want to run Chrome OS virtualized in VMWare Fusion on my mac. While it seems Parallels Desktop has a quick and easy method for running Chrome, the same can't be said for VMWare.
the most common resource for Chrome OS builds is http://chromeos.hexxeh.net, but it hasn't been updated in years. Meanwhile a new source — http://arnoldthebat.co.uk/wordpress/chromium-os/ — provides images for VirtualBox and as .img, neither of which I've had any luck getting to work. despite attempts to dd the images to USB disks, or convert the .vdi files to .vmdk, the results are always the same: "no operating system found" when VMWare tries to boot.
it would seem there ought to be a community resource for providing containers, or appliances, that VMWare can run with the latest builds of ChromeOS. if anyone knows of such a source, I'm all ears.
