This is because br0 will bring up the components assigned to it.īridge_stp off is a setting for spanning tree. Note: the lines auto eth0 and iface eth0 inet manual are not in the file. To set up a bridge interface, edit /etc/network/interfaces and either comment or replace the existing config with ( replace with the values for your network): If you make a mistake, though, it won't come back up. If you are on a remote connection, and so cannot stop networking, go ahead with the following commands, and use sudo invoke-rc.d networking restart or sudo reboot at the end. Modifying /etc/network/interfaces will disable Network Manager on the next reboot. If you are using NetworkManager, and want to continue to do so, do not use this method. This assumes you are not using NetworkManager to control your network cards (eth0 in the example's case). We are going to change the network configuration.

Install the bridge-utils package: sudo apt-get install bridge-utils This is covered in a website at /configure-linux-bridge-network-manager-ubuntu.html. You can use Network Manger to set up your bridge. Details are covers on the Network Connection Bridge page. You can do this from the command line or a script. This allows network manager to stay, but you have to remember to start the bridge before starting the VMs which use it. This works well, but does disable network manager so may not be best for desktops. You can set up your system to boot with a bridge. Network Monitoring Bridge - An in-line sniffer page. Installing bridge utilities - A similar page from a Bridge-Utils point of view. Network Connection Bridge - An in depth page on bridging. NOTE: Bridging is popular, and so it has reference material in several places that may not all be updated at once.

Warning: Network bridging will not work when the physical network device (e.g., eth1, ath0) used for bridging is a wireless device (e.g., ipw3945), as most wireless device drivers do not support bridging! If your guests do not have connectivity 'out-of-the-box' see Troubleshooting, below.īridged networking allows the virtual interfaces to connect to the outside network through the physical interface, making them appear as normal hosts to the rest of the network. If this configuration is suitable for your purposes, no other configuration is required. You should be able to ssh into the host OS (at 192.168.122.1) from inside the guest OS and use scp to copy files back and forth. The guest will be able, for example, to browse the web, but will not be able to host an accessible web server.īy default, the guest OS will get an IP address in the 192.168.122.0/24 address space and the host OS will be reachable at 192.168.122.1. In the default configuration, the guest operating system will have access to network services, but will not be visible to other machines on the network. If you are confused, the libvirt Networking Handbook provides a good outline. NAT is performed on traffic through the host interface to the outside network.Īlternatively, you can configure Bridged Networking to enable external hosts to directly access services on the guest operating system. The default virtual network configuration is known as Usermode Networking. There are a few different ways to allow a virtual machine access to the external network.
