<p>Hi Peter,</p>
<p>I had not anticipated this much response. I do have VLANs on my
switch(s). We are a modest operation and I configure without the
use of any config tool as such. <br>
</p>
<p>I would love to see your configuration, even if for Puppet, I
expect it will be informative/helpful!</p>
<p>Thanks for the offer.<br>

<div>Paul, if you can set up a VLAN on your network
infrastructure between the two hosts, I'll share the recipe I
use with Open VSwitch. We trunk a VLAN between our hosts for
sandboxed guests, setting up a OVS bridge on each host that
handles guests but also has a connection onto the VLAN. Are
you using any configuration tool? I've got this in Puppet but
should be able to convert to a shell script.</div>

<p>Thanks Laine,</p>
<p>I will take a look at Open vSwitch, it looks interesting.</p>
<p>I am a generalist, I need to know enough about a lot of
things to get many different tasks done, but do not have
the in depth knowledge required to "patch" anything. If I
manage to wrangle a working solution should I post it?</p>
<p>Needless to say I would be supportive of said feature
being implemented by those more competent than I...<br>
</p>
<p>Jocularity aside, thanks for the heads up on Open
vSwitch.<br>

I couldn't find any documentation on this, hopefully
someone can point me in the right direction. <br>
<br>
I recently set up a sand-boxed environment for our
developers. There are domain controller(s), workstations
and servers in there. The whole thing is running on a
single host using a "Virtual Network" defined in
virt-manager on that host. <br>
<br>
Now I find I want to add more guests and there are not
enough resources on this one host. Can I somehow make
this Virtual Network available to two hosts? I do not
want to move to a bridged network and have to physically
join the two hosts with a discrete link when they are
already on the same subnet at the host level. <br>
<br>
Is that possible? <br>

You might be able to this using OpenvSwitch (iow "probably
can, but I don't know the details" :-)) but libvirt
doesn't have anything to set it up for you; you would need
to create and configure the OVS switch outside of libvirt,
then attach the libvirt guests to that switch (using
"<interface type='bridge'> ... <virtualport
type='openvswitch'> ...") <br>
<br>
I've idly thought about having this as a libvirt feature
over the years, but as I never have that many guests, it
was never a personal priority, and it wasn't immediately
clear what was the best way to handle, e.g. DHCP, and
routing to the outside. Definitely "patches are welcome"
though :-) <br>
