openvswitch

Hi, so I recently separated out a dedicated storage network on VLAN 99 so it does not need to go through my pfSense box. Performance is good, I get around 9.3Gbs/s from a VM to my TrueNAS host. When going from a VM to another VM however, I only get around 6-7Gbs/s. Here I thought I might get a...

So my configuration is as follows: eno1 - trunk supporting vlans 101, 102, 103, and 200 eno2 - trunk supporting vlan 254 Server is connected to a Cisco Nexus 3064PQ configured in switchport mode trunk for both links with the appropriate vlans added on. There are no default tags for any of the...

I'm trying to use pools and roles to allow limited user self-service, but I'm stuck on allowing them to create their own VMs. The sticking point appears, I think(???) to be that I'm using OpenvSwitch. Openvswitch works great for my needs, but I don't see any permissions for it in the PVE...

We have been using a mixture of traditional Linux bridges as well as OpenVSwitch. Looking at the roadmap, I can understand a desire for stability but OpenVswitch is now well established, it's even available in the GUI now (and usable once apt install openvswitch-switch). It's also "under the...

Problem Statement PVE Host cannot ping or communicate to VM on same host, only when that VM is in a specific vlan (that is shared with the host). Issue persists across hosts, but always only the one specific vlan has issues - guests in another vlan (also with a vlanX interface on the host) work...

HP DL380P G8 CPU: E5-2650L x2 Memory: 384GB PVE 8.0.4 ovs-vsctl (Open vSwitch) 3.1.0 So recently i have been running into an issue on one of my proxmox servers. From time to time when trying to modify a network adapter i will get an error saying the guest is not running and then the change...

Hello, I would like to know how the ifupdown2 and OvS implementation in proxmox works because on a VM of my pve, I have a trunk that comes from the OvS of my PVE but when the VM is restarted the OvS service requires a restart for the flows to work whereas when I restart the pve it works...

Hello, before I was using a traditional setup with Linux Bridges and a pfSense VM. Recently I made the switch to OpenVS (mostly because I just wanted to try it out). I now have the following setup: auto lo iface lo inet loopback auto enp1s0 iface enp1s0 inet manual auto enp4s0 iface enp4s0...

Hi, I have a Proxmox host running a dedicated server from OVH. They provide both a single public IPv4 address, and a IPv6/64 block. I'd like to route all the IPv4 traffic from containers on my host through NAT, but set a proper public IPv6 for direct access. I've succeeded in getting the IPv4...

I have a Kubernetes VM and an unrelated VM on the same host in a cluster using an ovs-bridge. I'm able to ping between the two VMs but when I try to ping from a kubernetes container it fails. Using tcpdump on the ovs-bridge interfaces I can see ping and response on the unrelated VM's interface...

Hello community, we observe a strange problem here (Cluster on PVE 7.2-3 with open vSwitch): The ICMPv6 NS (Neighbor Solicitation) packet does not seem to arrive inside the VM (it is a Cisco C9800-CL Wireless Controller) when the vNIC has "firewall=1" set. As soon as we remove the "firewall=1"...

Hi! I am building a 3 node testing cluster where each server has 2x 1Gbps ports and 2x 10Gbps ports. 1Gbps ports are connected to different switches within same network (simulating a real environment) and 10Gbps ports are connected directly between servers. I read the following guides and my...

Hallo zusammen, Ich habe vor Kurzem OpenVSwitch auf meinem (einzelnen) Node installiert, die Bridge und IntPorts für die einzelnen VLANs eingerichtet. Der PVE Host sollte auch über ein VLAN erreichbar sein, dazu habe ich beim entsprechenden IntPort mit dem VLAN Tag die IP-Adresse und das...

PVE 7.1.1 5.15.27-1-pve openvswitch-switch openvswitch-common

Would be nice if Proxmox add option to handle patch ports for OpenVSwitch in UI. I achieved a working configuration by: /etc/network/interfaces auto lo iface lo inet loopback auto enp2s0 iface enp2s0 inet manual ovs_type OVSPort ovs_bridge vmbr0 auto vlan100 iface vlan100...

As stated in the title, I upgraded last night. I made no changes to my network interfaces file, and now my network is inaccessible. The only way I can get networking to work between my LAN network (and none of my others) is reverting to the original network config provided when I installed PVE5...

Hi guys! We use PVE 6 (pve-manager/6.4-13) with openvswitch network configuration and use ceph. And now we having problems with network routers. There is a buffer overflow on them since the traffic from the cluster is not marked Is it possible to configure traffic marking, for example, ceph...

After upgrading to ifupdown to ifupdown2 (as part of PVE7), I have a problem to configure NetFlow with ovs_extra in /etc/network/interfaces. Following statement worked in ifupdown: ovs_extra --id=@nf create NetFlow targets=\"10.0.20.20:9995\" active_timeout=60 -- set Bridge vmbr0 netflow=@nf In...

Hello, I just updated PVE from 6 to 7 with an OpenVSwitch configuration. With ifupdown it seems like my /etc/network/interfaces will be ignored. Installing ifupdown2 solved the problem - though you have to setup a temporary internet connection to download the package. It's odd that ifupdown2...

After recently upgrading to the latest version we started seeing these errors in the kernel on a few nodes. We are using openvswitch, the only thing I found using google that might explain the problem is this: https://lkml.org/lkml/2020/8/10/522 Before the update we were running kernel...
