You have been subscribed to a public bug: When installing a machine which is to be a VM host, it is necessary to make arrangements for the networking for the VMs. By default at the moment this is done by having libvirt create a "virbr0" bridge. The physical network interface is not enslaved to this bridge. Instead, all of the VM's traffic is routed, and natted, through the host.
This is appropriate for a laptop and perhaps for some desktops. It's definitely not appropriate for servers. For servers, the physical interface should be enslaved to the bridge; the networking parameters in /etc/network/interfaces should be applied to the bridge, and VMs should speak directly (ie, bridged) to the local LAN. (By default.) Ideally this should be done by having the bridge be set up by ifup ie configured in /etc/network/interfaces. Apologies for not knowing exactly the right package for this bug report. ** Affects: libvirt (Ubuntu) Importance: Medium Status: Incomplete -- virtual machines should not have nat on servers https://bugs.launchpad.net/bugs/865515 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
