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...

Hi Folks, I have performance issue with a 3 node cluster PVE 8.4 (all updated installed) on network side Hosts are using Intel 710QA2 adapter which are 40Gb QSFP+ 2 port nic. connected through a 5700 HPE switch which obviously support 40Gb connection. Firmware of the card has been updated to...

Hello, it is my first thread so sorry in advance for errors. So just some context. I have an cluster with 6 nodes, all on PVE 8.4- Currently they are running on the internal network interface on the mainboard. I need to add an NIC and let it run over it and use the internal one for intel KVM...

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)...

Hello, we have a strange problem with the Proxmox server. We have DELL R760 servers with 4 x 25 GbE onboard cards (Broadcom) and an additional 2 x 25 GbE AddOn PCI card (Broadcom). A LACP Bond 802.3ad has been set up. The bond is stable. However, if we fetch data via this channel from a VM from...

Hi, I want to buy a 2.5GbE NIC for my Proxmox servers. I wonder what would be a better choice... I was thinking about Intel I226-V. Supposedly there are fewer problems with it than Intel I225-V. Or maybe choose something with Realtek chipset? If so, which Realtek chipset works best with...

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...

Dear All, I can not update my PVE installation because I can not connect to proxmox. After I'm googling here and there, it seems like the problem is related to the realtek 8169 driver of my NIC. The problem is, every solution needs me to update and then install needed software/driver. But for...

I need to use a software in a vm that is locked to the mac address of the network card. My license exist for the mac address of the physical network card, but setting the same mac address for the vms virtual NIC, means that it will not get access to the internet :( I don't care of the mac...

I am running a PVE cluster (3) on 6.8.12-4. I have a Dell R730XD, and 2 R630s. 2 boxes have the Intel(R) 10GbE 4P X710 rNDC, and the other has the BRCM 10G/GbE 2+2P 57800 rNDC. iperf3 runs great between my NAS and PVE hosts (and their containers), but not on the VMs runnings on those hosts...

Good morning! I'm completely green as it comes to glass. So I ordered the next hardware, hoping I understood enough from the info I gathered all over the place. 2 NIC's: Intel X520-DA1, 82599EN (https://www.amazon.nl/-/en/dp/B01GHTXHMK) Intel X520-DA2, 82599ES...

I did setup a new promox node, and after setting up nic to a VM as hostpci other nics are gone from my setup. they should work as bond1 and vmbr1. root@pve2:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd...

Hello Until now, I have been using the RJ45 port on the motherboard, but I purchased the X520-DA2 and SF10G-AOC-01 to support 10G. However, when I connect only the SFP port, I cannot access the Internet or other local devices. I will write the interfaces file. enp4s0 is the RJ45 port, and...

Hi I've just got a new router (2.5G) and along with this I got some 5G network cards I've swapped it all over and got the drivers working. I have 2 NICS in the server - One is connected to the access point at 2.5G, however I've connected the other directly my pc with another 5G card; I was...

Hi I have pfsense as a VM router. I have recently bought a 10gb quad network card and am wondering what the best setup is here. Should I keep it as it is now, Proxmox bridging the connections and passing a virtual one for LAN, or should I pass the whole (Or ports) of the card. My worry is...

So i just installed a new interface which i had laying around (it was really cheap). And my goal is to use that INterface in a other Network. But i doesnt show up in the webgui and int the interface file it also doesnt show up. Is the Interface maybe incompatible with Proxmox or are some...

Hello! we upgraded two of our PBS servers from 2.x to the current version 3.1.4 and while doing that we encountered an issue. Both servers are identical except that server 1 uses an additional 10G network card while server 2 got a 40G Intel card (XL710-BM2). The first server upgraded without...

Hi, I'm basically a complete noob when it comes to Proxmox. I recently got an IBM branded Intel 39Y6138 NIC from a colleague. It was working in his machine, but when I try to utilize it in my Proxmox VE server it doesn't show up. The core specs of the server: CPU: Xeon E5-2690 RAM: 32GB MB...
