@mruffell Thanks for re-verified my comment in #65 and provide the test kernel.
The solutions are under Kernel team's discussion. Reverting is an option, but not the best. Actually, it's not a kernel issue. We are still working on it. Please wait a moment.

This shows up in VBox.log as "VCPU0: Guru Meditation -2708 (VERR_VMM_SET_JMP_ABORTED_RESUME)". I suspect this may have started due to a Linux kernel upgrade I installed this morning. A fresh VM with no disk shows the issue. Sometimes turning off the I/O APIC makes the issue go away, sometimes not. Turning off nested paging sometimes lets VirtualBox make a little bit of progress w.r.t. booting VMs, but that usually still crashes before the VM finishes starting.
