 So ... with {{{-d int,cpu_reset}}} we get:
 {{{
 ...
 wait for delivery
 deassert INIT
 wait for delivery
 num startups = 2
 send STARTUP
 wait for delivery
 send STARTUP
 wait for delivery
 done trampolining
 CPU Reset (CPU 0)
 RAX=0000000000000000 RBX=ffffffff801b3160 RCX=00000000c0000101
 RDX=00000000ffffffff
 RSI=0000000000000040 RDI=ffffffff801b3160 RBP=ffffffff81004fd0
 RSP=ffffffff81004fb0
 R8 =ffffffff801a2110 R9 =0000000000000000 R10=0000000000000028
 R11=0000000000000000
 R12=0000000000000000 R13=0000000000000000 R14=0000000000000000
 R15=0000000000000000
 ...
 }}}

 In other words, there's no triple-fault or anything that I can see, the
 CPU just unceremoniously resets. I added {{{-d guest_errors}}} and that
 produced nothing else, either. What's going on here?
