We trunk a vlan down to the hosts, make it the KVM traffic label for the guest network (we run VPCs in advanced mode) and allow ACS to build the VXLAN VNI within the vlan.
The native VXLAN support in the linux kernel uses multicast, so you do need an ip on the interface (we use a different network per cluster). We utilize both Whitebox and Brocade switches, all 10G SFP+ for frontend and backend connectivity. Each host blade has 4 x 10GB, 2 for the front end and 2 for the storage connectivity. The VR terminates the guest network, and you can then plugin a vlan in for public and private gateway access. We'll actually be presenting our design in Miami at the Cloudstack Conference, so ilya, you have an excuse to make the trip now! - Si ________________________________ From: ilya <ilya.mailing.li...@gmail.com> Sent: Friday, April 14, 2017 3:17 PM To: users@cloudstack.apache.org Subject: Re: OVS Plugin Hi Simon Would you mind expanding a little more on your setup?
