Unsolved Help me understand KVM Networking

Just click on your connection and go to edit -> connection details and click on the Virtual Networks tab.
Click the plus
Then run through the wizard.
If you choose NAT instead it will still work but is kind of pointless since you will already have an address through the macvtap.
You can do this through virsh as well. The host uses dnsmasq to configure everything so you can also add reservations and all of the other goodies as well. For reservations you can just add it in after the range line:
<host mac='de:ad:be:ef:ca:fe' name='test-vm' ip='192.168.30.50'/>

Works perfectly.

Too bad ovs isnt in the repos for RHEL/CentOS. You can set up these private networks and connect them through a VXLAN with ovs. That way you can have something like a separate dev network on the same hosts and they can communicate between hosts.

Not available in the epel repo?

That is apparently the case unless my google--fu isn't up to snuff

I will have easy access to the VM, but not the host, because of "reasons" that have nothing to do with IT.
You can't access the host externally, as in you will only be able to access the host via one of it's guests? That seems like a weird requirement.

Yes it is. Yet, if I drive 5 hours to be on site, I can have all the local console I want.
As I stated, not IT related reasoning.

Nope. It is available in Fedora though. If you want to install it you have to manually build the RPMs. While not hard to build it would be a pain to maintain updates.

OVS is used by oVirt so maybe the centos ovirt repo has it (or the ovirt stable repo)

I'm assuming it's just building the RPM since it's not in the normal repo.
