xenguest network bridge
Introduction
xenguest-network-bridge is creating a network bridge to allow some guests to have a direct connection to the external network. To do this, a bridge is created on the host using brctl with the network interfaces added to it so that the bridge is connected to the external network. It is also adding a guest init script which will, for guests configured to use it, create a virtual network interface for the guest and connect it to the network bridge on the host.
Usage
On the host the package xenguest-network-bridge must be included in your image.
On the xenguest image of your guest, the parameter NETWORK_BRIDGE must be set to 1 (using xenguest-mkimage --set-param=NETWORK_BRIDGE=1).
Bitbake parameters
Several parameters are available to configure the xenguest network bridge during Yocto project compilation (those can be set in your project local.conf, for example).
The following parameters are available:
-
XENGUEST_NETWORK_BRIDGE_NAME: This variable defines the name of the network bridge that is created on the host during init. This is set by default to "xenbr0".
-
XENGUEST_NETWORK_BRIDGE_MEMBERS: This variable defines the list of network interfaces that are added to the bridge when it is created on the host during init. This is set by default to "eth0".
-
XENGUEST_NETWORK_BRIDGE_CONFIG: This variable defines the configuration file to use to configure the bridge network. By default it points to have file configuring the network using dhcp. You can provide a different file using a bbappend and make this variable point to it if you want to customize your network configuration.
-
XENGUEST_IMAGE_NETWORK_BRIDGE: This variable can be set to 0 or 1 on guest projects to enable or not the connection of the guest to the host bridge. This is set by default to "1".
