[panda-users] Fwd: confused about panda_ssltut.md

[xiaojuan Li]

the process is this:
I used qemu-system-x86_64 to boot
system(debian_squeeze_i386_standard.qcow2),then in the qemu monitor,I input
"begin_record ssltut",after did something in that system,I input
"end_record",this should create ssltut-rr-snp,and then when I use
"qemu-system-x86_64 ***** *****
-loadvm ssltut-rr-snp",it just showed the problem I described before.
so I have that question how can I make sure that the record finishes?If
so,why the ssltut-rr-snp shows nothing?
Thanks!
