You can try:

1) first, please post the exact QEMU command line your using;

2) put "strace -e poll" in front and post the final lines.  Also post
the output of "ls -l /proc/<pid>/fd" where <pid> is QEMU's pid.

3) if the output of "strace -e poll" hangs, instead, run it under gdb
and post a backtrace.  Perhaps continue the process a few times and
check if the backtrace remains the same or changes.

Paolo
