Ubuntu 12 on Win 7 won't start

[ckr]

Hi. I just tried to create an Ubuntu 12 (x64) desktop guest using VirtualBox 4.3. It apparently failed because it errors out the instant that I try to start it up. So I deleted and tried to create a new one, first running the image before installing it. It ran fine. However, once I installed it, the exact same thing happened: It errors out immediately upon startup.

Not really sure what to do or why this is happening. I have 2 Linux lamp servers (one prebuilt, one not) running, a windows 8.1 box and a windows 7/64 box -- all on Virtualbox and everything runs just fine (although getting windows 8.1 to actually work required some command line instruction).

I'd cut and past the exact error I'm getting, only the error window that comes up helpfully prevents that. It says, however, that "a critical error has occurred while running the virtual machine and the machine execution has topped. For help... "

I'm running an AMD x64 processor and Virtual Box is running on Windows 7 64. I gave ubuntu 30 gigs of HD space and 8gig of ram, so that shouldn't be an issue. As I mentioned, other Linux boxes I've created worked.

It wants me to upload the png file, but there's no point in that, as the file is simply a black screen. It also says to load the log file, which I'm going to attach.

Any help here would be appreciated, as I'd like to get the desktop up and working.
Thanks!

PS -- it'd be REALLY useful if, since logs are required, this forum wouldn't gack when I try to upload it. 128kb? seriously? So... no log

Compress it and we only need the one that say vbox.log or the one that shows the error, not all 4

I was only trying to load one log, but I wasn't aware it was okay to load a zip file, so here it is.

Thanks!

VirtualBox VM 4.3.0 r89960 win.amd64 (Oct 15 2013 12:34:17) release log
00:00:22.297745 Oracle VM VirtualBox Extension Pack (Version: 4.3.2 r90405; VRDE Module: VBoxVRDP)


First thing I would do is upgrade your VirtualBox to 4.3.2 especially since you are using 4.3.2 Extension pack and see if that helps.
Extension packs need to match the running version of VirtualBox and then there is the possibility that your issue that is causing these triple-faults were fixed in 4.3.2.

Okay, that sounds like a plan. Although I wasn't trying to load the extension pack into this Ubuntu build. If I upgrade Virtualbox do know if it will cause issues with the other VMs I have?

VMs are not touched. The ext pack is installed on the host and you already have the ext pack for 4.3.2. See the first two lines.
