qemu uses prctl() to set its process title. I bumped up against prctl()'s
16-character limit recently, when adding process title support to
libvirt[1][2].
The attached patch overwrites argv instead. Linux seems to maintain the
length of the original args, even when the new args are shorter and
NULL-terminated, so the trailing whitespace in ps(1) output is probably
unavoidable. I've seen the same result with other daemons that overwrite
argv.
