Thnx.  So lets say I previously created a bridge interface and linked in my
eth0:
$ nmcli connection show
$ nmcli connection delete <eth0|eth0-UUID>
$ nmcli connection add type bridge \
         ifname br0 con-name br0
$ nmcli connection add type bridge-slave \
         ifname eth0 con-name eth0 master br0

Presumably I create tap0 then add it to my br0 such as the following:

$ nmcli connection add type tun \

          ifname tap0 con-name tap0 \

          mode tap owner `id -u` ip4 0.0.0.0/24
$ nmcli connection add type bridge-slave \
          ifname tap0 con-name tap0 master br0

Then I would be good to go with qemu and be all-set "automagically" at
every reboot as autoconnect=yes is set by default.

NM1.2 not yet available under Ubuntu 16.04 alpha (duno if planned to be
included?) so can't test it unless I recompile from source.  Therefore in
the meantime it's more of a personnal knowledge thing than anything else.

Thnx in advance!
