[Qemu-devel] Accessing a linux guest's data structures

Hi I am a beginner qemu developer. I am running a linux guest inside qemu and I need to determine what process, thread is currently running in the guest. How should I do this? Any suggestions? Or can anyone point me to the relevant areas in qemu's source. Thanks. Ankur Dahiya

[Qemu-devel] [PATCH] qemu_timedate_diff() shouldn't modify its argument.

The caller of qemu_timedate_diff() does not expect that tm it passes to the function will be modified, but mktime() is destructive and modifies its argument. Pass a copy of tm to it and set tm_isdst so that mktime() will not rely on it since its value may be outdated. Signed-off-by: Gleb Natapov
