Virtualbox 4.2.16 causes Windows 7 host (64bit) to power off, and other problems

[nico-cr]

I run a single guest, Ubuntu 12.04, on a Windows 7 (64-bit) host, a quad-core i7 with 8GB of RAM. The guest has 2GB of RAM and 3 processors.

Both the host and guest are up to the latest patches.

Problems:

• sometimes the guest causes CPU to get pegged at 100% -- CPUs, even if I set the affinity of the VBox processes to just some CPUs

• sometimes the host system just powers off

Nothing else was running when the system powered off.

This has been going on repeatedly since I updated to 4.2.16.

Before the update to 4.2.16 I'd noticed the first problem a few times, which is why I updated. And yes, I've shutdown the guest since the update (but not before the update -- I'd only saved the running machine state).

This is happening so much it's intolerable. I can reproduce almost at will: just build Heimdal (​https://github.com/heimdal/heimdal) and then "make check". At some point the CPUs get pegged, or the system powers off.

This makes it nearly impossible for me to get anything done. Help!

I meant 64-bit, not 640bit...

Also, I've no files to attach. I didn't get anything interesting from the host, nor from the guest.

No custom firewalls were running. Windows Security Essentials was the only anti-virus installed. OpenAFS was also installed but not in use and I doubt it was causing any problems.

Well, task manager and resource monitor were also running, as I was using them to monitor CPU and memory usage.

About the shutdown, check the CPU shutdown temperature, in the BIOS, then check the CPU temperature while running CPU intensive applications (not necessarily inside VirtualBox).

Please attach a VBox.log file of such a VM session. This will show the VM configuration.
