    Is this a good topology for segmenting VM internal networks?

    Hello everyone, We are currently evaluating using Proxmox for our development environment, and possibly homolgation and production if it all goes well. Right now I have a cluster with 6 servers, connected to our servers VLAN. Since we have several separated development teams, some using...

    [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, vmhost1

    Datacenter Networking

    Hello PVE enthusiast, I am currently administering 4 Proxmox nodes and each one is siloed so there is no direct networking between nodes. the network setup on every node is the same (it's the basic bridged network that i saw in every PVE setup tutorial): These are the linux bridges that i have...

    Proxmox 8.0.4 SDN Questions

    Howdy everyone! I have a cluster where we want to use the VXLAN features of the SDN plugin (I know it is an experimental feature and we accept the associated risks). 1. Is there an API endpoint or other automation that others are using for this feature? 2. Are there any issues using SDN with HA?

    Integrating Proxmox SDN with existing SDN network

    I've been trying to integrate the Proxmox SDN into an existing vxlan network using IS-IS. This way we'll be able to use the different vnets across multiple clusters as well as bind that to a vlan to attach legacy devices. Our lab setup is using a route-reflector on a spine switch and 2 leaf...

    Incorrect MTU calculation when CT sending packets over bridged VXLAN port

    We have an overlay network (configured as described below) which worked fine on PVE6.4 but after migrating the containers to a PVE 7.2 node have noticed some odd behavior, with packets above a certain size being discarded by the vxlan interface, but only when sent from a container, VMs continue...

    How to setup VLAN in Proxmox Cluster for VM communication on different nodes

    Hello guys, I can't get the communication right between VM's on different Nodes (Proxmox Cluster). I read some posts about VLAN and VXLAN (Proxmox SDN experimental feature). I decided to try it with VLANs first, as VXLAN is also marked experimental. I'm not even sure, if it's achievable that...

However, when I try to set a VLAN tag on a guest VM NIC which is using a VXLAN VNET, I get the following error: no physical...
