When the operand passed to VMPTRLD matches the address of the VMXON
region, the VMX instruction error code should be
VMXERR_VMPTRLD_VMXON_POINTER rather than VMXERR_VMCLEAR_VMXON_POINTER.

Sigh. Mis-applied patch. Update forthcoming.

VMXERR_VMPTRLD_VMXON_POINTER was completely unused so far. This is 
correct (Vol. 3C 30-16 and 30-29).

Jim, I don't see your emails on the list (that don't Cc me) after Nov 4.
Have you posted more than this patch and the checkpoint/restore series?
([PATCH 0/8] kvm: nVMX: Checkpoint/restore support for VMX state)

I'm sorry they fell through cracks.
(Still no idea why -- filters don't even delete mail.)

Just one, I think: [kvm-unit-tests PATCH] Test 32-bit ljmp emulation.
