Thanks for the info.

Followed the guide and modified my VLANs config accordingly. DATA0IF now
has it's own dedicated interface. I reinstalled the OpenStack application
but it failed while installing the openstack-libvirt chart.

Install log: https://pastebin.com/FAdV3tMe

neutron-ovs-agent-controller-0-937646f6-dprsc_openstack_neutron-ovs-agent-init*.log
seems to also point to an error: https://pastebin.com/GcC2bjBj

I'm also seeing these messages appear periodically in dmesg:

[11998.657984] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[11998.658070] IPv6: ADDRCONF(NETDEV_UP): cali29ecf54f2e7: link is not ready
[11998.658073] IPv6: ADDRCONF(NETDEV_CHANGE): cali29ecf54f2e7: link becomes
ready
[11998.658079] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[11998.783788] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[11998.783869] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Any help appreciated,

Marc
