    PVE Version 8.2.7 Hello I have been running a PVE cluster of 4 nodes for some time, and started using SDN (VXLan) since even before release. All worked rather stable, but recently one node started having problems. SDN spans between nodes via static IPs, and has a few VNets. Three nodes...

    How to assign IP to nodes when using vxlan SDN

    Hello, I have 6 nodes to build a cluster, and I used vxlan as the sdn zone. Now I can create new VM inside the vxlan, and the VM could connect each other. However, I also want to let nodes connect VM, which means I need to assign IPs within the vxlan to nodes. I have tried to update the...

    Connecting nodes to VXLAN SDN

    I have a proxmox cluster with two nodes with SDN VXLAN configured. Connections between containers and VMs work very well, also from different nodes. Unfortunately, I fail to connect the nodes themselves to this VXLAN. Could someone please help?

    Cluster-Wide Virtual Firewall using SDN

    Hi all, I've been reading up on the PVE docs, reading some articles and watching some YouTube videos on how proxmox's SDN works. This gave me an idea of a setup for my homelab, which I think should work, but I'm not too sure how to configure it in the SDN zones/vnets. My home network has...

    SDN / EVPN: Ping not always working between Virtual Machines

    We have multiple (9 now, 15 on their way) Proxmox hosts in our 2 datacenters. Each node has an eBGP connection to two switches (ptp subnet /31) for the underlay with an unique Private AS number (ie. SW015 AS 4200000102 -- PRXMX01 || AS 4200000103). In the SDN controller each host has EVPN...

    Advice for Traffic Accounting (bytes-in, bytes-out) on Bridge Ports or VXLAN for many VMs

    Our network consists mostly of 10 Gbit/s switched backbones to the internet. On the network we have a cluster of Proxmox VM hosts with around a 100 VMs. We have the need to do traffic accounting, per VM, in the most efficient manner. We don't need to count protocol traffic flowing via internet...

    [SOLVED] VXLAN SDN route/MAC address mismatch after migration

    Hi all! I've discovered an issue with VXLAN and routing, and I'm not sure if it's because my setup is wrong/weird or if it's a bug (possibly in the kernel). My setup is: Three nodes in a cluster, each node has an /32 address on loopback lo: vmhost0 10.200.255.10/32, vmhost1 10.200.255.11/32...
