Guru Meditation -31 with Linux SMP Guest

Reported by: kyndigen Owned by:
Priority: major Component: VMM
Version: VirtualBox 3.0.4 Keywords:
Cc: Guest type: Linux
Host type: Windows


I hit a Guru Meditation -31 (VERR_PAGE_TABLE_NOT_PRESENT) while running a parallel make inside a 4-core Linux guest. I've seen guest kernel panics (null pointer exception) with this guest setup whenever I give the guest more than 1 CPU ever since 3.0.2. This is the first one that has been detected by VirtualBox, so I can finally generate a bug report.

This failure was on a Windows 7 RC (build 7100) host with a Linux guest (2.6.30-gentoo-r4). I also see similar crashes on a 2-core MacOS host with an identical guest kernel. If I can get it to crash and produce a Vbox.log under 3.0.4, I'll include it here as well.

I tried some additional test cases:

Fails on VBox 3.0.0 and 3.0.2. Fails with guest kernel 2.6.29-gentoo-r5. Fails on MacOS host with VBox 3.0.4 without Guru Meditation dump. The kernel panics, and the host CPU utilization goes to 100%.

The Windows host has nested paging and VPID extensions enabled. The MacOS host does not since the CPU in that box does not support those extensions.

Have the same issue on CentOS 5.3 x86_64 host and Fedora 11 x86_64 guest (kernel When I give guest more than one CPU, it crashes. In guest I see kernel panic, in host - 100% cpu utilization by VBoxHeadless process. VBox version is 3.0.10.
