Problem with trace of x86 binary on x86_64 system with PANDA

Problem with trace of x86 binary on x86_64 system with PANDA

[Nikita Gnilozub-Volobuev]

Hello there.

I'm a student and I'm writing my term paper. Part of it is the record 
the trace of x86 ELF on x86_64 Linux. For record I use PANDA. And I 
stacked with very strange problem: there is no system calls in my trace.
When I see this I was very surprised and make simple grabber of 
translation blocks. As I know I must see in that sysenter (0x0F 0x34) 
and int 0x80 (0xCD 0x80). But nothing of them was in my blocks. Maybe 
trouble is in TCG? How I can test this and proxing system calls through 
PANDA for analyze it?
For example what I mean: I have very stupid binary, it's just write 
"Hello world" to file. But PANDA can't catch any calls. Even write 
although it is clear that this call must be there.

Hi; PANDA is based on a fork of an older version of QEMU, with
considerable alterations. You are probably best off asking your
question on a PANDA specific mailing list or forum.
