libvirt users - May 2014 - Can I assign a dedicated NIC to a container?

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?
Any comments will be highly appreciated.

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.
