network adapter

I'm new to Proxmox. I installed it on a Lenovo ThinkCentre M90Q with 32 GB RAM some 2 weeks ago. Installation went fine with 9.0.11 running. Continued with a VM running Home Assistant, also no problem at all. Fixed IP on both Proxmox host and the Debian VM running Home Assistant. It's been...

Hello everyone, I hope you are good, I am a Linux sysadmin, who are using Proxmox in DEV env after having used VMWare, and I came across this strange issue, which is having 3 Proxmox bare metal hypervisors running VMs and VM's can't connect to the internet but the hypervisors yes. I have the...

Hello, I'm new to Proxmox VE and have a problem configuring my first server's network. I'm using an onboard Intel network card (I219-V, driver e1000e) and an external USB 3.0 network card from Realtek (RTL8153, driver r8152). The Intel I219-V is configured for a peer-to-peer connection to my...

My environment was good until I decided to try to pass my PCI NIC to a VM. I must have selected the wrong device ID because after attempting to power on the VM my PVE web kept getting disconnected. Now I am unable to get into the webui as it does not load. My integrated NIC is two 10G and two 1G...

Hello I've added an additional network card into my proxmox computer. This causes a "device-rotation" (related to the network device names / numbers in proxmox) and a connection lost to the proxmox mgmt-ip. Old naming of the network devices (before inserting the new network card) was...

Hello, I upgraded my whole homelab today to PVE 9 and PBS 4. All went well for PVE, but I lost network connectivity on my PBS instance. Hardware is a Dell Wyse 5070 and I have this in the logs: System worked without issues before upgrading. How can I further troubleshoot and fix this issue...

I'll start off by admitting I am very new to proxmox - I had really only just gotten it set up and some containers running on it when this happened - so I apologize if I am not totally accurate with my terms. I am running Proxmox on an old Dell PowerEdge R330. This has a dedicated IDRAC port...

Greetings Proxmoxians! I am on the cusp of building a new cluster with 3 Dell servers. Each server has two dual-port 25Gb/s NICs, for a total of 4 ports. From a high-level, I'm counting roughly 4 functions that the network needs to perform: Management access (SSH and web UI) to the hosts...

Hello, I'm having some strange behavior when using an i225-LM, x520-da or x550-t2 NIC and the Virtio network adapter in Proxmox. Those cards use theigb and ixgbe drivers, respectively. The issue only occurs on VMs in which I use Moonlight/Sunshine to gamestream from a VM with a GPU passed...

Hello, I have a question. I would like to increase the number of NICs on my PC with Proxmox VE installed. I am thinking of using a USB wired adapter to do this. However, I am wondering if there are any specific restrictions or settings on the Proxmox side. The Proxmox version is 8.3, and the...

Hi everybody! I am new to Proxmox, OPNsense and Homelabbing. I have follow a lot of tutorials from "Jim's Garage" and "homenetworkguy", but I can't resolve my problem. I am trying to build my fully virtualise homelab. So, this is my configuration: - One Desktop PC (ryzen 9-3900x and 32GB ram)...

Proxmox provides us with ability to enter IP on the ethernet adapter. But while connecting that to a Linux Bridge it will complain that the ethernet adapter has IP settings. What is the use of setting IP directly on Proxmox adapter? I have generally seen IP being applied to the Linux bridge...

Hello, Have upgraded my UnRaid server recently (5900XT/X570-P/Adaptec 71605/Intel X710-DA4 FH/64GB Unbuffered ECC), and have now made the move to Proxmox. Have set up a few VM (UnRaid, Debian, OPNsense). So far I've just used the motherboard port for most things while I've been setting up and...

I recently needed to change the IP structure of my proxmox cluster. I broke the cluster and changed IPs. I have one system that has lost the vmbr0 interface which has completely caused the system to loose network access. I currently only have IPMI access. Here is info on the system: Proxmox...

I installed Proxmox over Debian 12 so I could keep my Windows partition on the machine I'm running the server on. After I installed Proxmox my ethernet did not appear to work on the machine (only wifi worked, which is what I used when installing Proxmox over Debian 12, not sure if that has any...

Hello, I have created a proxmox server on a Dell Optilex 7010 computer which only has an RJ45 socket. More and more servers are being created on it. My question concerns the availability that can be configured so that the computer remains permanently accessible from the local network. Is it...

I recently upgraded my NIC to a 4 port 10GBE. after this nothing network related and I have looked at multiple other times this happened on the forums and none of them helped. I have uploaded photos of some of the things that I commonly see requested. All of my CT and VM are booting up but not...

I am facing a strange issue with my OPNsense + Proxmox. I am using an ODI DFP-34X-2C3 XPON ONU with a MCX312B-XCC_Ax and sometimes (quite frequently tbh) when rebooting the VM (OPNsense) or the entire Proxmox, the mlx4_en: enp3s0d1: Link Down attached to the OPNsense bridge goes down and never...

Trying to standup a new node with an iso install of v8.3 and can't get past early part of the installer because it complains there are no NICs found/acceptable. Read a bunch of threads about realtek issues here. Not sure if that's my issue yet. To workaround/test, I tried installing Debian 12...
