[libvirt] [PATCH v2] nwfilters: Test suite for checking created firewall entries



Changes from v1 to v2:
- followed suggestions from Eric Blake on script improvements

This patch adds new test cases to the existing nwfilter test program and
adds a test script that must be run while a VM is running. This test
script verifies that input network filter XML creates expected
user-defined tables and rules on ebtables, iptables & ip6tables layer
and verifies their content against expected content. The idea is that
these tools always return exactly the same output when displaying the
content of a user-defined table so that the diff tool can be used for
simple text comparison. All supported protocols have at least one test
case. 
This test program is not run automatically since it requires a running
VM.

For all tests to pass the previously posted ICMP fix patch must be applied.

+
+Run this program while a KVM VM is running (preferably as only VM on the
+system) and one of its interfaces uses a filter called 'testcase'. The name
+of the interface of the VM is anticipated to be 'vnet0' unless set by the
+'--ifname' option. The following interface description fulfills this
+requirement:
+
+    <interface type='bridge'>
+      <source bridge='virbr0'/>
+      <target dev='vnet0'/>
+      <filterref filter='testcase'/>
+    </interface>
+
+The individual tests are validated using string comparison where the output
+of ebtables, iptables and ip6tables is compared against expected output. As
+long as the output of those tools is the same, the tests should all pass.
+The tests were developed on Fedore Core 12.
+
+Known problems: None of the running VMs' names may have spaces.
