It's working for me with both the CD and DVD ISOs, although I've had a few "events". I'm on a wide screen computer this time, which was fine until I started the Stellarium program; that seemed to have issues with the unusual aspect ratio and sudddenly I couldn't mouse to parts of my screen. Things went down hill from there, including loss of background. I was able to reboot and things seemed ok again.
I then hit some problems after running IceWeazel (which is giving some really ugly fonts on this forum), which might be a manifestation of the already reported screen 2 - 3 - 4 lacking toolbar, but I soon had a completely black screen with no known way to get to a toolbar or regain control. A forced shutdown didn't help; the virtual machine just restarted in the same state with an error message about a restart script. I couldn't figure out any other way to get the VM right again so I deleted the current set of files for the virtual machine and put the original set back in.
Strangely, on boot this time there was a kde error message and the screen didn't automatically adjust to the proper size, but after a little coaxing it seems ok.
The clock is 6 hours fast from my EST setting, not quite sure what that's about, seems a little too fast to be on GMT (which I think is only 5 hours off my time zone).
So the VM is working and letting me boot and run the ISO. Not without little things to investigate, but that's how we learn.
