Manjaro (Kernel 4.9): Random freezes of VM

Posted: 17. Feb 2017, 15:31
by Cathodoluminescence
Hello!

since a few days I have the problem that my VM freezes after a few minutes. The manager is stating that it still runs, and I also can't see anything suspicious in the log file. If I change the window size, it will be recorded in the log, but nothing else from the moment it freezes.

Please post a VM log file. With the VM fully shut down, right click and "Show Log" in the GUI, save "VBox.log" (no other file) to a zip, and attach the zip here.

I was trying to put it in here as code, but the board did let me... here is the file!

And thanks for any help!

Everything looks pretty good, except... I see that the VM only has one CPU core assigned, so the VM freezing would be a natural consequence of a guest process hogging the CPU. Your host has 4 cores, so you can afford to let the guest have two. Then it should be easier to pop up the guest tasklist and find out the CPU hog is. BTW, if this was an XP VM then it wouldn't start using a second core just because you allocated one. In XP you had to manually replace the HAL. I don't know whether Win7 is any smarter - it ought to be.

By the way, what kind of disk is your host drive "/run/media/c1/ssd2"? I gather that it's an SSD, but on what bus? (Internal SATA, eSATA, USB2, USB3, network etc)?

Interesting. How do you tell if the XP machine isn't using two cores assigned? I have an XP guest and it shows 2 (of 8 ) cores in the Device Manager but have wondered at times how slow certain jobs run on it. Maybe only using one because I never made any changes to HAL? Task Manager shows two cores also. Just curious, thanks.

EDIT: (answered) Thanks socratis and mpack

You pretty much answered your own question.

Go to the Device Manager (right-click on the computer » Properties » Hardware » Device Manager). Expand Computer. If it says "ACPI Multiprocessor PC", then you've installed the HAL that supports more than one CPUs. And it shows in the Task Manager. That choice is made during the XP installation depending on the amount of CPUs that you have during the installation.

If you had installed XP with a single CPU, the Computer would say "Advanced Configuration and Power Interface (ACPI) PC". If that was the case and you later decided to increase the number of CPUs, XP would not see them. At all. It would only use one CPU.

So, bottom line, if you see more than one CPU in the Task Manager, you're all set.

For me the clearest display of this in XP is the task manager. You go to the performance tab, and if it shows two CPU performance history windows then you have two cores. If it only shows one window then its only using one core.

Why would you use a system folder to store the guests? (/run/media/cl/ssd2/VM/RamanVM/RamanVM Clone-disk1.vdi)
Permissions are root:root so it means you would have to run in root or change the permissions to allow you to do so. Either is a major security risk and not the way VirtualBox was intended to run.

I am running it from a secondary SSD as my the primary one does not have enough empty space. I don't think I gave VirtualBox any special rights, but then again, I set it up over a year ago!

To everyone else: I am running a Win 7 32 bit machine. And it run like this for at least a year or so. I added a second core in the configuration and it seems to run again. Not sure, why it wasn't running anymore with a single core, but thanks a lot!

That implies that it was running, but it was maxing out the core on some task (cough: windows update). You should have been able to find this task in the guest task manager, as already mentioned. Of course it may have taken ages to get around to popping up the task manager window, but that should be less of a problem now that it has an additional core to do that with.
