I don't really feel qualified to do a good review of patches for 
libvirt-tck, but since you've taken the time to add in tests for code 
that I wrote, I felt it my responsibility to respond :-)

First - Thanks for adding this in!

Looks like I need to be careful where I run the libvirt-tck, as one of 
the networks chosen for testing will clobber the route to an important 
internal network (10.0.0.0/8) for the duration of the test.

Aside from that, and the indenting issue I mention below, it looks like 
these tests follow the pattern of previous network tests you've already 
committed, and they seem to be looking at the right things (although 
they seem a bit fragile - any change to the way we invoke radvd or 
dnsmasq will cause the test to fail, right?), so I would give a 
conditional ACK (after fixing the indentation) just because more testing 
is better than less, if for no other reason :-)

It might look nicer for this XML to be indented.
