[panda-users] problems with replay

[alessandro mantovani]

Hello,


I've correctly installed PANDA on ubuntu 14.04 and I've created e qcow2 image for windows xp sp3 with the following commands:


qemu-img create -f qcow2 winxp.img 20G

x86_64-softmmu/qemu-system-x86_64 -m 256 -hda winxp.img -cdrom Scaricati/windows_xp_sp3.iso -boot d


After that I start the system with:


x86_64-softmmu/qemu-system-x86_64 -m 256 -hda winxp.img -monitor stdio


In the QEMU monitor I can start and end recording with:

begin_record test

end_record


Now the problem: when I close QEMU and I wants to have the replay I use the following command:


x86_64-softmmu/qemu-system-x86_64 -m 256 -hda winxp.img -replay test


But I get a segmentation fault. The output is:


loading snapshot
... done.
opening nondet log for read :    ./start_test_record-rr-nondet.log
RR rr_assertion `current_item' failed at /home/elmanto/panda_installation/panda/panda/scripts/panda/panda/src/rr/rr_log.c:813
Current log point:
{guest_instr_count=6148}
Next log entry type: RR_INPUT_4
Current replay point:
{guest_instr_count=6144}
Annullato (core dump creato)


Consider that I've cloned the PANDA repository yesterday so I assume that there aren't obsolete files. Do you have ideas??

Thank you,

Alessandro
