<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>

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?

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 :-)
