I just downloaded the VMWare appliance for Chrome OS.i686-0.4.223. There seems to be no way to change the screen resolution from 800x600. VMWare tells me that the VMWare Tools are out of date.
I tried shutting down the machine and adding the CD Rom drive so I could add the VMWare Tools, per the instructions in VMWare. Turns out you need to install
kernel-source --- but even then, I can't get the VMWare tools to compile, because the source code for the kernel that the Chrome_OS is running isn't in the repository.
