I can only make it fail if I emulate a machine with multiple processors and I leave SMP enabled in the kernel. If I either emulate a uniprocessor machine or disable SMP via tunable, the VM is able to boot without crashing. To summarize, I believe that I am running into two separate issues with VirtualBox 4.0.6: - Booting off of an emulated SATA drive leads to crashes during boot: http://people.freebsd.org/~rstone/vbox-4.0.6/VBox.log (Guru Meditation -4001 (VERR_VMX_INVALID_VMCS_PTR) ) - Booting a VM with multiple virtual processors on a kernel with SMP enabled crashes during boot: http://people.freebsd.org/~rstone/vbox-4.0.6/VBox-SMP.log (Guru Meditation -4002 (VERR_VMX_INVALID_VMXON_PTR))
