Hello, Paul. You have implemented the second part of the proposal, which is related to Qemu hook. Unfortunately, Qemu hooks are not always the right place to implement features. I would like it to be, but it's not because of: https://www.libvirt.org/hooks.html#recursive In my case, I even

Yeah, being able to handle EVPN within ACS via FRR would be awesome. FRR has added a lot of features since we tested it last. We were having problems with FRR honouring route targets and dynamically creating routes based on labels. If I recall, it was related to LDP 9.3 not functioning

Linux native VXLAN uses multicast and each host has to participate in multicast in order to see the VXLAN networks. We haven't tried using PIM across a L3 boundary with ACS, although it will probably work fine. Another option is to use a L3 VTEP, but right now there is no native support for

We've also been using VXLAN on KVM for all of our isolated VPC guest networks for quite a long time now. As Andrija pointed out, make sure you increase the max_igmp_memberships param and also put an ip address on each interface host VXLAN interface in the same subnet for all hosts that will

Hi Wido, I have "pioneered" this one in production for last 3 years (and suffered a nasty pain of silent drop of packages on kernel 3.X back in the days because of being unaware of max_igmp_memberships kernel parameters, so I have updated the manual long time ago). I never had any issues (beside

VXLAN and KVm experiences

Hi, I just wanted to know if there are people out there using KVM with Advanced Networking and using VXLAN for different networks. Our main goal would be to spawn a VM and based on the network the NIC is in attach it to a different VXLAN bridge on the KVM host. It seems to me that this should
