I have started to use SDN network and it's work with VMs. I have created a cluster and I've added a new node. In this node SDN network is pending "local sdn network configuration is not yet generated, please reload" and /etc/network/interfaces.d/ is empty. Do I need copy files manually?
All...
Hello,
we try to build a PVE Cluster with a EVPN VXLAN SDN.
The configuration for the VM to VM Communication is working, also SNAT with the Subnet Gateway is working.
Now we try to replace the subnet gateway with an external OPNsense, so that the OPNsense can provide all required network...
Hey there,
I have this strange issue with the current Proxmox 8.1 SDN-module, where DHCP replies don't arrive at the destination VM.
I assume following setup:
I assume that this setup works as expected, in that it pushes VLAN 90 onto all packages in vnet22A9, and every packet entering...
On a root server with one NIC I set up Proxmox VE 8.1.4 with two SDN simple zones, so I have three bridges configured: vmbr0 connected to eno1 with public IP, dmznet with SNAT and subnet 192.168.100.0/24 for nginx reverse proxy. Third bridge is labnet 192.168.200.0/24 for the application...
Hi all, i just upgraded from 7.4 to 8.1 and was trying to experiment with SDN. If I add a Simple zone, i cant seem to turn on DHCP anywhere. I did install dnsmasq. It's like there is no dhcp plugin at all. What am I missing?
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...
Hello,
we want to setup Simple SDN zones with IPv6 but can't find any documentation about how to configure SLAAC or DHCPv6 for a Simple SDN zone in the WebUI.
Goal:
Netcup-VPS with two public static IPv4 addresses and two public static IPv6/64 prefixes -> Headscale VPN -> Proxmox VE node ->...
Hi, I configured 2 Proxmox 8.1.3 servers in one cluster and configure SDN zones as VXLAN.
1. No option turn on DHCP
2. When SNAT checked on subnet, no snat rules
/etc/pve/sdn/zones.cfg
vxlan: vxlan
peers 10.33.3.20,10.33.3.21
ipam pve
mtu 1450
nodes pve1,pve...
Hi,
I'm testing the new SDN feature with some servers that are going in DC soon, I only get DHCP working with the simple zone.
I can recall that I read somewhere that it was only working with the simple zone, is that still true, and if so is there any idea when it will work with vxlan? like a...
Hi,
I just want to know how do you guys manage the networking for big proxmox clusters ?
In my case I need to have multiple external networks for my VMs. For that, I create a dedicated vlan on my network switches and then configure a linux vlan interface on top of my linux bond and then add a...
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...
Hello,
I have a problem that I'm using VLAN SDN zones and at almost every VNet it looks good. But one VNet has a problem with packet loss (ping between VMs at same VLAN at same / diferrent nodes).
I have a stack with 4 nodes, connected via 2x 25Gbps LACP (DACs to nexus 9300 series).
This is...
Hello everyone.
I'm trying to restrict permissions to certain VNets. In the Proxmox API Viewer the ACL paths are listed as /sdn/vnets and /sdn/vnets/{vnet}, but if I try to set these permissions I always get the error 400 Parameter verification failed. path: invalid ACL path '/sdn/vnets'.
I'm...
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?
Hi,
on a up-to-date setup with two nodes, the only difference being the kernel version (because of https://forum.proxmox.com/threads/32-bits-openbsd-vm-unbearably-slow-after-kernel-5-13.129909/#post-570343 that i havent found time to bisect)
pve-manager/8.0.4/d258a813cfa6b390 (running kernel...
Good day,
is there perhaps a template/documentation/examples for implementing a custom IPAM for the ProxMox SDN side?
I'm looking at https://spritelink.github.io/NIPAP/ for IPAM as we roll out the next steps of our network, so obviously the question comes in w.r.t. PVE not (yet) supporting...
hello,
I wonder if it is possible to configure SDN for servers with multiple NICs.
For example, I've servers with 4x10Gb Nics, I want to configure
- two of 10Gb Nics as Guest Network with BGP EVPN enabled.
- another two of 10Gb Nics as PVE host management + external Ceph cluster connection...
We ran into a very nasty issue a few days ago.
Background:
Systemd generates ridiculously long interface names (see https://manpages.debian.org/bookworm/udev/systemd.link.5.en.html and referenced here https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES) like...
This is my current infrastructure:
Defined on the Mikrotik are a couple of VLANs for ipmi, proxmox, ceph, and for user networks going across the Mikrotik switch. I have 3 (W)LAN user networks.
When a new project is started I need to define a new isolated network and vlan in router and add it...
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...
