Hi. 

Just upgraded a small 3 nodes cluster to 6.4 today. This cluster used the SDN feature with a single VLAN zone, and a few vnets (each one of the vnets using a VLAN tag, and not VLAN-aware themself). 
I see several issues regarding SDN since the upgrade : 

    * The biggest issue is that in Datacenter -> SDN I only see a single node (with the status "available"). The other two do not appear anymore. Without paying attention, I clicked on the "Apply" button. This wiped the /etc/network/interfaces.d/sdn file on the 2 nodes which do not appear anymore, and reloaded their network stack. Needless to say it was a complete failure as all the VM attached to one of those vnets lost network connectivity. I've manually copied this /etc/network/interfaces.d/sdn file from the only working node to the other two for now, but I can't make any change from the GUI now or it'll do the same again 
    * In Datacenter -> SDN -> Zones, my single zone didn't appear anymore. No Zone were displayed at all. But the Vnets correctly showed they were attached to my zone. /etc/pve/sdn/zones.cfg correctly had my zone defined here. I tried adding it again from the GUI, which seemed to work. The only change it made to /etc/pve/sdn/zones.cfg is the new "ipam: pve" option added to the existing zone 

Anyone know what could be wrong ? Why would 2 (out of 3) nodes not showing up in the SDN status anymore ? 

The 3 nodes are fully up to date using the no-subscription repo, here's the complete pveversion :
