[Solved] VM Machine with warning "Critical Error occurred"

Post by GMM »

I upgraded to v5.2.0 and receive the following error message and then it freezes.
Host is Windows 7 x64 PC.
Running a Windows XP VM w/SP2 and it worked previously.
A critical error has occurred while running the virtual machine and the
machine execution has been stopped.
I checked the Hardening log and it shows no error message. The last line reads:
Quitting: ExitCode=0x0 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 554195 ms, the end);
1aa8.19d0: supR3HardNtChildWaitFor[1]: Quitting: ExitCode=0x0 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 555039 ms, the end);
I can upload the VBox.log file if that would help.
Any ideas on what to try?

As explained in the Diagnosing VirtualBox Hardening Issues post, an ExitCode of zero (0) means that there was no hardening problem involved, but rather that something else is going on.

Well, then you got to ask yourself what changed between previously and now. There are a couple of things that I can think of, both involving VT-x and its unavailability. 1) Hyper-V, or 2) something using VT-x exclusively that got updated, like an antivirus.

Take a look at another post, I have a 64bit host, but can't install 64bit guests. Please go thoroughly through that and get some potential ideas on what might be "stealing" exclusively your VT-x. You might have an option in your antivirus to disable "hardware assisted" scanning.

If that does not work, start the VM (don't resume, clean start), observe the error, close the VM (shut it down, or abort it). Right-click in the VM in VirtualBox Manager, Show Log. Save the first only VBox.log, ZIP it and attach it to your response.

I was able to load the VM in SAFE MODE but still unable to load normally.
Not sure what significance that is, but I will review your recommended posts when I return from a business trip in ten days.
By the way, I have never investigated the VT-x/AMD-v in the host PC BIOS issue so hoping that helps, but since I've not changed PC's since VM worked, not sure why the BIOS would have changed.
In any case, I will go through each of the steps in the links and post my results on my return.
Thanks for the response and links.

It's yet another sign that VT-x is not available when your host is running. Something is grabbing VT-x, and you need to dig a little deeper to find out which program that is.

I am attaching the ZIP log file which was created on a clean start of the VM along with a screen shot showing the error message.
I also tried to determine if a program is grabing the VT-x but could not locate the service. Does anyone know how to find which program is affecting VT-x?

You don't need to attach a screenshot of the error message if you can simply describe it. And certainly not in a PDF, ZIPPED format. Just a PNG inline would do. But kudos for actually cropping it to the region of interest.

There you go. Official confirmation...

Just do a quick search for "VERR_REM_VIRTUAL_CPU_ERROR" and you'll see that the unavailability of VT-x is indeed your problem...

Nope. That's the problem. I told you where to get some "ideas" and general guidance. But unless I'm sitting in front of your computer and going through each and everyone of your installed programs, no, I can't.

Solved - I made the change to the BIOS setting and "Enabled" the vt option. Completely turned off the PC and after the reboot, it seems to be working.
Thanks to all who guided me through the steps and pointed me in the right direction.

PS To socratis - Next time I will place screen shots in line as a PNG. :)

Great, thanks for the feedback. Marking as [Solved]. And your pictures will look prettier next time... ;)
