+# Creation and configuration of the bridge interface with archlinux
+
+Debian based system ? no problem => [http://lesaventuresdeyannigdanslemondeit.blogspot.fr/2013/03/mise-en-place-dun-bridge-sous.html](http://lesaventuresdeyannigdanslemondeit.blogspot.fr/2013/03/mise-en-place-dun-bridge-sous.html)

+
+## Bridge interface
+
+Create a virtual bridge interface `/etc/systemd/network/MyBridge.netdev`
+
+```sh
+[NetDev]
+Name=br0
+Kind=bridge
+```
+
+
+## Bind ethernet to bridge
+
+Modify the `/etc/systemd/network/enp3s0.network` to remove the DHCP, as the bridge requires an interface to bind to with no IP, and add a key to bind this device to br0. Let us change its name to a more relevant one.
+
+```sh
+[Match]
+Name=en*
+
+[Network]
+Bridge=br0
+```
+
+## Bridge network
+
+Create a network profile for the Bridge `/etc/systemd/network/MyBridge.network`
+
+```sh
+[Match]
+Name=br0
+
+[Network]
+DHCP=ipv4
+```
+
+
+Finnaly restart `systemd-networkd.service`
+
+# Qemu config for use bridge

+
+Edit file (if folder not exist, create it) : `/etc/qemu/bridge.conf`
+
+```sh
+allow bridge0
+```
+
+# Start qemu
