Started guest with '-s', tried to attach from gdb with
"target remote localhost:1234", got
"remote 'g' packet reply is too long: <lengthy string of numbers>"
Tried typing 'cont' in the qemu monitor, got os x to crash:
panic (cpu 1 caller 0xffffff7f813ff488): pmLock: waited too long, held
by 0xffffff7f813eff65
Hmm, maybe that's where it keeps its monitor/mwait idle loop.
Restarted the guest, tried this from monitor:
dump-guest-memory foobar 0xffffff7f813e0000 0x20000
Got "'dump-guest-memory' has failed: integer is for 32-bit values"
Hmmm... I have no idea what I'm doing anymore at this point... :)
