Re: [libvirt] [PATCH v2] qemu: Start domain on a node without cpu affinity

qemuProcessInitCpuAffinity prevents a VM from getting started on a platform that uses cpu affinity wrapper stubs e.g. macOS. The patch adds qemuProcessInitCpuAffinity stub on all platforms without HAVE_SCHED_GETAFFINITY or HAVE_BSD_CPU_AFFINITY.
