[Qemu-devel] Execute QEMU "the same"

[Lyu Mitnick]

Hello all,

I am wondering to know whether QEMU could run "the same" twice. ie. the same of execution trace.

I read the user manual and find options like:  "-clock dynticks -rtc base=2006-06-17T16:01:21,clock=vm -icount 1".

Would QEMU run "the same" with these options??

PS. I also found the function cpu_io_recompile() with comments:

      /* in deterministic execution mode, instructions doing device I/Os

         must be at the end of the TB */

      But I don't know the means of deterministic execution mode and how to turn on it.

thanks a lot

Mitnick
