Dear all, There are two containers hosted by my host machine. And the host machine has two same 1G NICs. I want to assign a dedicated NIC to one container. The host and the other container share the second NIC. How can I achieve this?

There are several options for the dedicated NIC - Use <hostdev mode="capabilities" type="net"> http://libvirt.org/formatdomain.html#elementsHostDevCaps This simply moves the host NIC into the container's network namespace, making it invisible to the host, and only usable by that one container - Use <interface type="direct"> http://libvirt.org/formatdomain.html#elementsNICSDirect This connects the host NIC to a container via macvlan device. This can also be used for the shared NICs.
