Allow users to specify a file for trace-outputs at configuration. Also, allow trace files to be annotated by <pid> so each qemu instance has unique traces. The trace file name can be passed as a config option: --trace-file=/path/to/file (Default: trace ) At runtime, the pid of the qemu process is appended to the filename so that mutiple qemu instances do not have overlapping logs. Eg : trace-1234 for qemu launched with pid 1234. I have yet to test this on windows. getpid() is used at many places in code(including vnc.c), so I'm hoping this would be okay too.
