This breaks libvirt capability probing. I see qemu running: /home/kraxel/projects/qemu/build-default/x86_64-softmmu/qemu-system-x86_64 -S -no-user-config -nodefaults -nographic -M none -qmp unix:/var/lib/libvirt/qemu/capabilities.monitor.sock,server,nowait -pidfile /var/lib/libvirt/qemu/capabilities.pidfile -daemonize and libvirt is stuck until I kill qemu. cheers, Gerd
