With Eric Blake's suggestions applied. The following rule for direction 'in' <rule direction='in' action='drop'> <mac srcmacaddr='1:2:3:4:5:6'/> </rule> drops all traffic from the given mac address. The following rule for direction 'out' <rule direction='out' action='drop'> <mac dstmacaddr='1:2:3:4:5:6'/> </rule> drops all traffic to the given mac address. The following rule in direction 'inout' <rule direction='inout' action='drop'> <mac srcmacaddr='1:2:3:4:5:6'/> </rule> now drops all traffic from and to the given MAC address. So far it would have dropped traffic from the given MAC address and outgoing traffic with the given source MAC address, which is not useful since the packets will always have the VM's MAC address as source MAC address. The attached patch fixes this. This is the last bug I currently know of and want to fix.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
