[libvirt] Can jobs suck like qemu-pr-helper does be transfered to libvirtd?

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. # # # # # ___________ # ___________|libvirtd |__________ # | |___________| | # | | | # | | | # _________|________ _____|______ ___|____ # | qemu-pr-helper |__| vm1.sock |_____| qemu1 | # |__________________| |____________| |________| 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!
