You added all these new tests, but forgot that you made the MANIFEST
file static/manually edited in commit a140e4f61 back in May, so the new
tests don't get installed.


Also, the tests don't actually boot up an OS and try to pass traffic; I
guess that's something you're counting on someone adding later? :-)


(Same comment for adding the proper iptables rules, but we need to
consider what to do about that, because what gets added will in the
*very near* future be different depending on version of libvirt and/or
whether or not firewalld is using nftables).


Those last two shouldn't keep you from pushing the patch though (see my
list at the end for the few things that do need to be changed before
pushing)

This works to eliminate conflicts with active interfaces, but doesn't
take into account any routes that have the same destination
address/prefix as the desired network. For example, you may have a
static route for 192.168.125.0/25 pointing to another host that has a
routed virtual network with that address. If that's the case, the test
will fail.


I don't have a quick alternative at hand to suggest though, and the
likelyhood of a host having a static route that conflicts with the
lowest numbered available 192.168.blah.0/24 network is probably pretty
low, so I'm going to overlook this :-)

In the past (so long ago I don't remember the details) there has been
different behavior between transient and persistent networks and
domains. If we wanted to be pedantic, we could test it both/all ways. It
would be overkill to do all the combinations for *every test* though.
Since there are multiple tests here doing almost the same thing, we
could make one of them with a persistent network/transient domain, one
with transient/persistent, etc (or maybe just be sure there's one of
each type, not necessarily all combinations)

There shouldn't be a bridge device for a hostdev network. Removing the
line above is sufficient.


> +    $b->forward(mode => "hostdev");


This should also have 'managed => "yes"' for maximum ease of use (you
have to go to the trouble of blacklisting things or explicitly running
nodedev-detach to get the VFs pre-detached from the hostside VF net driver).

Sigh.


(That has nothing to do with this bit of code. I just happened to type
it in for some reason while this review email was up on my screen.
Probably it was meant for another window, I'm not sure. I was just kind
of amused to find it sitting here as I scanned through the message
before sending it, so thought I'd leave it in for comic relief).

Is the above some odd requirement of the way things are added into
existing XML?

Assuming the following:


* add new test files to MANIFEST
* remove $b->bridge("tck") from hostdev test
* add 'managed => "yes"' to the $b->forward(...) in hostdev test

(Yes, I actually added hostdevs and nics to the config file and ran
*all* the tests :-)
