binhong.hua 023334dfcb optimize qemu.conf
bump up the max_files to 32768 and max_processes to 131072.
when nova used ceph as backend, the default limit 1024 is not enough.
each connection from rbd image to osd needs 1 fd and 2 threads. if we
have 200 osds, we need 200 fds and 400 threads for 1 image.
