I/O threads and vCPU threads already support setting schedulers, but until now
it was impossible to do so for the main QEMU thread (emulator thread in the
libvirt naming).  This is, however, requested for some very specific scenarios,
for example when vCPU threads are running at such priority that could starve the
main thread.

v2:
 - news.xml addition in a separate patch

Martin Kletzander (6):
  conf: Parse common scheduler attributes in separate function
  conf: Format thread IDs optionally
  docs: Mention iothreadsched element in the docs and reword
  conf: Add support for emulatorsched
  qemu: Add support for emulatorsched
  docs: Add emulatorsched support to news.xml
