VERR_PGM_INVALID_PDPE_ADDR when starting VM in Windows KVM virtualized host

Description

When using the following OVA image (Ubuntu, 32 bit) in a 64-bit Windows 8.1 virtualized host under QEMU/KVM with nested virtualization, I get a VERR_PGM_INVALID_PDPE_ADDR guru meditation, and the VMM exits. Log is attached. I can boot other OSes successfully.

Usecase of nested virt is testing several buffer overflow assignment submissions for Rice University's security class. If need be, I can use another computer, but my primary Windows environment is currently virtualized.

FWIW: #14965 resolved VirtualBox crashing the virtualized host; I have a similar configuration.

Very low chance that anybody has time to look into this issue unless you can reproduce the problem on real hardware. Could be very well a KVM bug.

Found a workaround, FYI. Disabling nested paging solved my problem.

Please reopen if still an issue with a recent VirtualBox release.
