Hi all,
During some fuzzing with trinity in a KVM guest running on qemu, I got the following error:
KVM internal error. Suberror: 1

The assembly doesn't quite make sense, and the fact that I got 3 of these in a row, makes me believe that it isn't an actual emulation error, but something else.

This is cmpl $0x0,0x2c79f97(%rip) # 0xffffffff83d96800. I don't
understand why it failed, we do emulate cmp. I'll try to write a unit
test for it.

The assembly makes sense, it's sti; hlt; leaveq. What doesn't make sense
is that we have to emulate leaveq - rsp and rbp point at normal memory
as far as I can tell.
The fact that it often happens after hlt makes me suspect interrupts are
involved. Please run this again with a trace so we so what happens
prior to the error.
