130 The qemu-vmsr-helper is working very much like the qemu-pr-helper. Instead of
131 making persistent reservation, qemu-vmsr-helper is here to overcome the
135 MSR support activated and the qemu-vmsr-helper. A systemd service and socket
136 activation is provided in contrib/systemd/qemu-vmsr-helper.(service/socket).
138 The systemd socket uses 600, like contrib/systemd/qemu-pr-helper.socket. The
