virtualbox.org

I have a new macbook pro 15'' retina display laptop running OS X 10.8.3. I am running virtualbox v4.2.12 (I just updated it today). I downloaded Ubuntu 12.04 LTS earlier today and installed it as a virtual machine from the iso.

I then installed many packages using apt-get to run a certain piece of software I need. I did the normal:

sudo apt-get update
sudo apt-get upgrade

and then installed all the bits I needed, plus the software I need the virtual box for. Ubuntu also suggested some upgrades. I think there were some kernel upgrades but I never looked closely. Everything was working fine after installing the upgrades and new software. However, when I powered off the VM and then tried rebooting it a while later it does not boot. I see the virtualbox window appear (where I can hit F12) then the screen goes black/brown and nothing happens.

The VM rebooted several times during the upgrades and package installs with no problems. I've spent a couple of hours getting it to the way I need it and now it's not booting. Any ideas?

Cheers James

Please read Minimum information needed for assistance and include the VM settings command output on top of the guest log file please.

Sorry this was my first post. See below for more info.

See attached for the most recent log file.

Whoops, I sent that before adding the VM settings, see attached.

Please see the v4.2.12 discussion thread: I think this "Ubuntu not booting" issue already has enough threads covering it.

Do you have a link to the specific thread you mentioned? I have had a look through the forum and cannot find the v4.12.2 thread. Also a search returns nothing. Thanks

Discuss the 4.2.12 release.
