``nodelay`` disables the Nagle algorithm.
``unix options: path=path``
``unix options: path=path[,abstract=on|off][,tight=on|off]``
``path`` specifies the local path of the unix socket. ``path``
is required.
``abstract`` specifies the use of the abstract socket namespace,
rather than the filesystem. Optional, defaults to false.
``tight`` sets the socket length of abstract sockets to their minimum,
rather than the full sun_path length. Optional, defaults to true.
``-chardev udp,id=id[,host=host],port=port[,localaddr=localaddr][,localport=localport][,ipv4][,ipv6]``
Sends all traffic from the guest to a remote host over UDP.
