Hello Serge!

I think that this is, in fact, a bug.

Even using "vepa", the problem is the same.

My XML looks like this now:

---
    <interface type='direct'>
      <mac address='52:54:00:c4:c8:68'/>
      <source dev='ovsbr1' mode='vepa'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>

Same problem, guest IPv4 works, IPv6 does not!

The weird is that, if I start a Router Advertisement in my network, the guest receive the ICMPv6 and generate its own IPv6 BUT, it can not "ping6 anywhere".

ONLY "type=bridge" works for both IPv4 and IPv6 guest network.

Here is how I'm configuring my guests using virt-manager:
