qemu-system-x86_64: -replay: invalid option about panda

[phulin]

What's the full command line? You might be accidentally using the system
QEMU instead of the PANDA modified version.

Hey, having a dumb issue here, every time I try to replay a recording, I
get this error (and it is the only feedback I get from qemu):
qemu-system-x86_64: -replay: invalid option
I built it properly with build.sh without any errors so I don't really
get whats going on now huh

Thanks for the fast replay,

the full command line is:
me@stillme:~/Downloads/panda-master/qemu/x86_64-softmmu$ sudo qemu-system-x86_64 -m 1024 -replay '/home/me/spotify' -panda callstack_instr -panda unigrams

As you can see I'm trying to follow along moyix post on Push the Red Button to get to know PANDA

Yep, that's exactly the problem. You need to use "./qemu-system-x86_64",
not qemu-system-x86_64, which uses your system QEMU
(/usr/bin/qemu-system-x86_64).

Uuhm, it could be possible that I am retarded as fuck but yes, now it works but where is the difference????
And yea, actually it doesn't work, I'm getting a new error now: after the loading and the initializing of the plugins, I get:

loading snapshot
qemu-system-x86_64: Could not open VM state file
... done.
opening nondet log for read : ./spotify-rr-nondet.log
RR rr_assertion `rr_nondet_log->fp != NULL' failed at /home/frank/Downloads/panda-master/qemu/rr_log.c:1323
Current log point:

Current replay point:
{guest_instr_count=0 pc=0x00000000, secondary=0x00000000}

Should I create a new issue for that or can you help me directly?
