I tried to deploy hosted-engine over vlan over a bond and everything worked as expected but I also found a case where it fails: SetupNetworks is going to fail if bond0.123 is correctly configured with an IPv4 address while the untagged bond0 lacks IPv4 configuration.

Simply configuring a static IPv4 address from an unused subnet  on the untagged bond is a valid workaround.

I just opened https://bugzilla.redhat.com/show_bug.cgi?id=1586280

Ok, I removed all bridges, so IPs are configured on bond0.id, added dummy IP for bond0, flushed iptables. And it works. So thank you for your help!

One last question - does the bond0 IP is still needed or it's just issue during install and now we can delete it?

Cheers
