live CD boot hangs under VirtualBox and VMWare

[Benjamin Denckla]

I am unable to boot the live CD (and therefore unable to install) Ubuntu 12.04 i386 as a guest in the following virtual environments:

VirtualBox 4.1.14 for Mac (the latest)
VirtualBox 4.1.14 for Windows (the latest)
VMWare Fusion 4.1.2 (the latest)

The boot appears to hang fairly late in the game, at the point when, in a successful boot, the "Install" window comes up, offering you a choice between installing and just trying Ubuntu. Or that is what happens in 11.10.

In VirtualBox for Mac, the boot appears to hang with a screen that is black except for "Ubuntu Desktop" written on a ribbon at the top of the screen.

In VMWare, the install appears to hang at the same point in the sequence, but the screen shows the default Ubuntu background, but no "Ubuntu Desktop" ribbon.

In VirtualBox for Windows, the install appears to hang at the same point in the sequence, but the screen shows the default Ubuntu background, plus the "Ubuntu Desktop" ribbon, plus the mouse pointer works.

I have tried the install with 3D graphics both on and off in both VirtualBox for Mac and VMWare. My theory being (and still is) that the installer is actually trying to use Unity but the virtualized graphics driver cannot support that. I have not yet tried 3D on Windows.

On VirtualBox for Mac, I also tried booting with "nomodeset xforcevesa", with no difference in behavior.

For comparison, Ubuntu 11.10 installs fine in VirtualBox for Mac and Windows. I have not tried it on VMWare Fusion.

I have described this problem also at http://ubuntuforums.org/showthread.php?p=11896048

Thank you for taking the time to report this bug and helping to make Ubuntu better. While we appreciate the difficulties you are facing, it would appear that the CD image (ISO file) you downloaded could be corrupt. There is an easy way to verify the integrity of the Ubuntu ISO files you download. Could you please visit https://help.ubuntu.com/community/HowToMD5SUM follow the instructions and report back as to whether or not the MD5SUM verified? Thanks in advance.

Sorry, indeed it was a corrupt ISO!
