I am trying to download linux on VM. I have attached the error and log for this.

Any suggestions or assistance is appreciated.

Thank you

You're getting a triple fault error (error inside error handler inside error handler). It's hard to pin down the original error, but it usually means that the guest did something really nasty.

I note that the VM has a VDI hard disk, so this is not an attempt to boot an Ubuntu installer. Also one typically doesn't download Linux as a VirtualBox VDI (you might download it as an OVA appliance), so where did this VM come from? Can you give me the download link?

It is usually better to download Ubuntu as an ISO and install it yourself. The Ubuntu people make the install process very painless.


p.s. Your Windows host is not relevant to the question asked. Moving this topic to "Linux Guests".

Thank you for your reply.

The programs I am trying to work with need both windows and Linux platforms, so to prevent restarting multiple times we have decided to go this way. (Which has worked seamlessly for everyone but me.)

Its telling me I cannot post urls so I have attached a picture with the links I've used. [ replaced with actual links by mod ].


After receiving this error, I deleted and restarted the process but have not had any luck in proceeding. Any suggestions are greatly appreciated.

Text extracted from image by mod:
I downloaded the VM from https://www.virtualbox.org/wiki/Downloads and Ubuntu 12.4 from http://releases.ubuntu.com/12.04.5/ where I downloaded the ISO.
It suggested putting it on a hard disc which is where it's pulling from.

I assume "I downloaded the VM.." means that you downloaded VirtualBox, not that you downloaded from the Oracle images section at the bottom of the wiki/Downloads page.

If you downloaded an installed Ubuntu yourself then I have no idea what you might have done wrong. We had best wait for a Linux expert to come along.

Back up a second. You say you downloaded an ISO, and yet the log says that no ISO is mounted in the VM. The VM does however seem to be booting from a CD.

So how exactly are you mounting the ISO? What you should have done was mount the ISO directly in the VM using the Storage panel of the VM settings. Do not burn the ISO to a physical disk, and definitely do not use any kind of host OS virtual ISO mount feature.

Linux was burned to a disc. In the virtual box- going to settings/storage/IDE controller I have designated it to pull from that disc drive.

I also had it pulled from my downloads folder using similar setting but same error.

Don't burn the ISO to a disk. Mount the ISO directly in the VM, using the Storage panel of the VM settings.

You should also check that the ISO has not been corrupted, ideally by comparing your MD5 checksum with the download site.

Tried that again and confirmed the ISO has not been corrupted by comparing the MD5 checksum. Still getting the same error VINF_EM_TRIPLE_FAULT . If anyone has any suggestions on what I could try I would greatly appreciate it. Thank you

The new log still does not show the ISO being mounted directly in the VM.

I've looked up how to mount the ISO directly in the VM but sounds like what I've been doing... settings/storage/ click CD and under attributes, click CD and click "choose virtual optical disc file'. Then I'm choose the file from my downloads folder. This was a longer way about it but can also click and choose directly from main screen under storage.

I've attached my logs again as I'm not 100% where you are looking. If there is another way I should be going about this, please let me know.

Thank you

In that case I'll leave you for the Linux experts, as I mentioned before. Perhaps in the meantime you should try a different version of Ubuntu, or a different distro, such as Mint.

As mentioned triple faults are hard to figure out remotely. There are a few things that you can try to isolate the cause though.

First since this is a boot from CD you are booting to the live CD which is very generic and designed to work on almost every system out there. The biggest thing to watch out for is changing any of the default settings when the guest is created on the first run so you can test if the install media is going to work. In other words change nothing at all. If it boots or does not boot then we need to know why. You do not install on this test boot, just run to see if it works. By the way you can not do this test on this unless you delete and remove the current guest because the settings are already corrupt.

If the guest boots this way then the host is eliminated from further testing at this point. Now you can change a few settings like the RAM, and video memory, but unless you know for certain that something really needs to be changed I would suggest you leave them alone until you get more familiar with VBox and Linux.

Some things that you could do to test the current settings is to disable things to see if they are causing this issue. Disable the network, sound, and 3D acceleration on the settings and if this allows the OS to boot you can enable them one at a time to see which one causes it to fail. Make note of which one and post here along with a new log file and the additional information posted below.
Note to self for reference. cpu seems to be mis-identified as p4 instead of xeon and msr may be incorrect
