The filter purpose is to simulate isolated private VLAN.
The behavior can be achieved by limiting network traffic
to traffic between VM and gateway. Because there is no
concept of the PVLAN in the linux bridge.
The filter also contains parts from clean-traffic
to prevent VM from spoofing its IP and MAC address.
To use this filter the user just needs to set
the GATEWAY_MAC variable to gateway MAC address.

Using one Makefile per example subdirectory essentially serializes 'make'
calls. Convert to one example/Makefile that builds and distributes
all the subdir files. This reduces example/ rebuild time from about 5.8
seconds to 1.5 seconds on my machine.
One slight difference is that we no longer ship Makefile.am with the
examples in the rpm. This was virtually useless anyways since the Makefile
was very specific to libvirt infrastructure, so wasn't generically
reusable anyways.
Tested with 'make distcheck' and 'make rpm'
The "maxMemory" element was never supported by libvirt. Remove it from
the test XMLs. (Found while actually trying to add support for a
identically named element).
'make rpm' with client_local set to 1 (by manual modification,
or with RHEL 5 on s390) warns:

The bulk of these are fixed with this patch.
* examples/xml/nwfilter/Makefile.am (install-data-local)
(uninstall-local): Make conditional.

* libvirt.spec.in: Remove obsolete --with-remote-pid-file arg.
Add missing %{without_libxl} statement. Fix handling of docs
in client only build. Put systemtap files in -client RPM
instead of -daemon RPM
* examples/xml/nwfilter/Makefile.am: Don't install examples if
nwfilter is disabled.
Fix a typing error in the no-ip-spoofing filter.
Return DHCP request packets passing through this filter. Have
the user use another filter to actually allow DHCP requests to be
sent (action='accept').
With fragments borrowed from David Steven's previous submission and some
further modifications:
A set of modifications to filters to handle multiple IP addresses
(and MAC addresses) per interface.
Also:
- enable DHCP traffic from VM to any DHCP server
- will require an update to a libvirt-tck data file

I went with the shorter license notice used by src/libvirt.c,
rather than spelling out the full LGPLv2+ clause into each of
these files.
* configure.ac: Declare copyright.
* all Makefile.am: Likewise.
This patch enables filtering of gratuitous ARP packets using the following XML:
<rule action='accept' direction='in' priority='425'>
<arp gratuitous='true'/>
</rule>
Qemu currently sends an Ethernet packet with protocol id 0x835 once a VM
was successfully migrated. The content of the packet looks like a
gratuitous RARP, just with the wrong protocol ID, which should be
0x8035. I wrote some filters to let either one of the packets pass and
am adapting the clean-traffic sample filter to use it. I am also
doing some changes on the existing ARP filter which was lacking a
test for source MAC address.
During an out-of-tree build, the current working directory is the build
directory. Since the FILTERS are static and not modified or
auto-generated during the build process, they need to be explicitly
fetched from the source directory during install.
Prefix the files with $(srcdir), which gets expanded to the absolute or
relative path to the source directory, even when duing out-of-tree
builds.
