[Qemu-devel] [PATCH 16/19] Port host_net_add monitor command to QemuOpts

[Mark McLoughlin <markmc@redhat.com>]

Here is where we rely on qemu_opts_parse() to handle an empty string.
We could alternatively explicitly handle this here by using
qemu_opts_create() when we're not supplied any parameters, but its
cleaner this way.
