Hi,
I would like to ask about status of VDE and libvirt. I found a thread
from http://www.redhat.com/archives/libvir-list/2008-February/msg00030.html.
I am not interested in connecting the VDE to the outside world. I have
created a FW machine using macvtap. To this machine I would like to
attach machines from different zones (dmz, prod, cust). I was thinking
on using VDE and vlans (FW would have 1 interface in each vlan -
machines also), but I am not aware how to configure this in libvirt.
I now assume I can do the same setup with regular bridges for the moment
(benefit of VDE would be only 1 switch for many vlans).
Regards,
Robert

AFAIK, vde_switch is still unsupported by libvirt and nobody seems to
work on it these days.
Most people wanting vde_switch (or open vswitch) enough leave libvirt.

Yes, this is what I do for now.

Plus more features (i.e.: easy virtual switch link between hosts),
maintenance facilities, etc.

On #IRC I got point to message:
http://www.mail-archive.com/libvir-list@redhat.com/msg32081.html
It seems there is a patch ready. I will test it against 0.9.0. What is
the procedure to get the patch reviewed and eventually get into libvirt?
I mean VMware has vSwitch and it is very powerful.
I'll checkout the vswitch as well.

libvirt?
The patch wasn't merged but the why is a question to the maintainers. I
guess the way it was implemented did not convinced. This is what I
understand from the whole thread, at least.

From the thread it seems the maintainers would like to have a network
based on VDE. To me it also looks like better idea (create vde network
and then just attach the domain to a network.

For my needs I would like to see either vdeswitch or openvswitch
integrated in the project. Is there any preference from the
users/developers on which one of those I should start looking into?
Also I would like to know how this should be integrated, from the mails
I can see devs prefers to have virtual switch present as a network. Can
someone describe how the integration should be done? Support for
additional features like vlan, QoS?

Are you volunteering to write some code? :-)
There have been requests for both, and both should eventually be done,
so I guess pick whichever one you like better :-) (since there's already
a patch for VDE, albeit with different XML than we'd like, that may be
quicker to finish.)
You may want to follow development of the work I'll point out below,
though, otherwise you could waste a lot of time.
Also I would like to know how this should be integrated, from the
mails I can see devs prefers to have virtual switch present as a
network. Can someone describe how the integration should be done?

Once we get into these kinds of questions, it's probably best to switch
to the developers' list (libvir-list(a)redhat.com) to get better exposure
to people writing the code. I'm Cc'ing this message there (and switching
the Reply-To: as well).
In particular, I recently send an RFC to libvir-list proposing an
expansion of the <network> XML to remove the hard-coded connection
between guest interface and host interface for macvtap (type='direct')
interfaces:
https://www.redhat.com/archives/libvir-list/2011-April/msg00591.html
and in a followup message showed how we could expand on this work to
provide support for openvswitch (or vde):
https://www.redhat.com/archives/libvir-list/2011-April/msg00640.html
I'm planning to have this code finished and tested within the next two
months at most (hopefully considerably earlier). If you're interested in
implementing a <network type='openvswitch'> or <network
type='vde'> you
should subscribe to libvir-list (if you aren't already) so that you can
follow along.

OK, I'll try to start with vde. I've subscribed now to libvirt-list as well.

I am now trying to compile the stuff, but I get:

But I'll figure out eventually.

But I'll figure out eventually.
libtool tells you that if found '-L /usr/lib' in the commandline, but
it would like to see '-L/usr/lib' (without the space). Typically this
comes from a "broken" pkg-config file from one of the libraries
libvirt depends on.
Run 'make V=1' to make it print the complete commandlines, this might
help figuring out from which library the problem comes.

rsmol@laptop:~/Code/libvirt (git:master)$ pcap-config --libs

I filled #775433 on ubuntu for pcap-config. modified pcap-config and now
I can compile the libvirt just fine. Moving on.
