The attached patch fixes a problem due to the mac match in iptables only supporting --mac-source and no --mac-destination, thus it not being symmetric. Therefore a rule like this one <rule action='drop' direction='out'> <all match='no' srcmacaddr='$MAC'/> </rule> should only have the MAC match on traffic leaving the VM and not test for the same source MAC address on traffic that the VM receives.
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.
