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:

Screenshot 2 - direct / mode=vepa - test you ask me to do

Thanks!
