64-bit Centos 5.5 VM crashes 32-bit Win 7 host on HP Probook 6450b laptop

[David Aldrich]

Hi

Host:

• HP ProBook 6450b laptop (Intel Core i5)
• Windows 7 32-bit host o/s
• VirtualBox 4.0.8
• VT-x/AMD-V enabled in BIOS

I have built 32-bit and 64-bit Centos 5.5 VMs. The 32-bit VM runs solidly on the above host, but the 64-bit VM crashes the laptop at random times (sometimes while the VM is starting, sometimes after hours of the VM running).

I have disabled automatic restart on system failure in System Properties of Windows, but the crash still restarts the laptop (I have McAfee SafeBoot installed, which is a disk encryption system, after the crash I arrive at the Safeboot login).

On another 6450b laptop, which was very recently delivered and so has up-to-date BIOS and drivers, we installed Win 7 64-bit o/s and found that the 64-bit Centos VM ran solidly with no crashes. We then rebuilt the same laptop with Win 7 32-bit o/s and saw that the 64-bit Centos VM crashed the host as on my laptop.

I have discussed this problem on the forums with no solution:

I will attach the log of a crashed VM to this ticket.

I don't know how to obtain a minidump but will get one if you tell me how.

Best regards

David

Most probably a duplicate of #9458. Please try if forcing the host Windows kernel to non-PAE works around this bug.

[David Aldrich]

I tried forcing the host Windows kernel to non-PAE mode as follows:

1) BCDEdit /set PAE forcedisable 2) reboot

but the Windows 7 32-bit host still spontaneously crashed when running the 64-bit Centos 5.5 VM.

So this is probably a duplicate of #11979. Please try the test build which is provided there.
