”This is the recommended config for general guest connectivity on hosts with static wired networking configs. Provides a bridge from the VM directly onto the LAN. This assumes there is a bridge device on the host which has one or more of the hosts physical NICs enslaved.” | ”This is the recommended config for general guest connectivity on hosts with static wired networking configs.

Silta on br0, jolla on ”hallussaan” (enslaves) eth0. | |||
”The guest VM will have an associated tun device created with a name of vnetN, which can also be overridden with the <target> element. The tun device will be enslaved to the bridge. The IP range / network configuration is whatever is used on the LAN. This provides the guest VM full incoming & outgoing net access just like a physical machine.” | |||
<tt>bridge.xml</tt>: määritellään silta br0 ja yhdistetään liikenne eth0 -> vnet0. UUID on luotu <tt>uuidgen</tt>:llä. | |||

”An ethernet bridge is a device commonly used to connect different networks of ethernets together, so that these ethernets will appear as one ethernet to the participants. Each of the ethernets being connected corresponds to one physical interface in the bridge.” | ”An ethernet bridge is a device commonly used to connect different networks of ethernets together, so that these ethernets will appear as one ethernet to the participants.
