Hi all:
qemu-pr-helper exits to help qemu do the high-privileged scsi related
jobs. LIBVIRTD is responsible to launch qemu-pr-helper and qemu, and set
selinux/DAC labels for them and their socket.

There may be other jobs quite like qemu-pr-helper, shall we make them as
"complex" as the qemu-pr-helper scheme?
Will it be OK to just let qemu send an EVENT to libvirtd, and let libvirtd do
the SCSI/other jobs? Will it be OK if we remove qemu-pr-helper and similar
processes?
What's the disadvantage if we let libvirtd do there high privileged jobs
instead qemu-pr-helper-like processes?
Thanks!
