network card

Steps: 1. Install PVE when PCI slot 1 is empty. 2. Close PVE, PCI slot 1 is inserted into the device. 3. Start PVE, and the network card light goes out after entering the PVE boot interface, restart still like this. Inserting a device in PCI slot 2 does not have this problem.

Hi, I have been spending my time setting up proxmox and exploring its capabilities, everything seems to work fine except a single thing that I came across. The problem is, when I modify any VM network configuration (net0), for examle set a speed limit or change the adapter to the intel one, the...

I have a server with Proxmox operating system installed, and I have created a virtual Windows 10 machine on it. The server is equipped with a Mellanox dual-port network adapter, each port capable of speeds up to 25 Gbps. When assigning the network adapter to Windows, I chose the virtIO model...

I had one Intel X550-T2 installed on my server and all VMs were running fine and I setup OPNSense and had it configured with the two ports from the X550 being LAN and the onboard ethernet being the WAN interface using bridges. However, for OPNSense to really replace my router, I needed more...

Hello everyone I have a 4 ports QNAP 2.5Gbits NIC that I passthrough my Opnsense VM and through that this VM is able to get an Internet speed of around 2.2/2.3Gbp/s so this is OK. On my Proxmox hypervisor i have another 2.5Gbp NIC that is used as a bridge for all LAN VMs. If i check with...

Hello, I have 2 servers with each one Mellanox ConnectX-4 100 GbE QSFP installed. >I connected the 2 with a Mellanox 100gbe DAC cable. and both idracs show me a link with of 100gbit/s. However when I run ipref3 on both ends I only get around 34gbit/s. I have read that iperf3 might be limited...

Hello Forum I have searched the forum for an answer for about a month now, but I am unable to find one, or a similar solution to my problem. Recently I made the decision to migrate to Proxmox as hypervisor after using VMware since 2012. It goes very well. I’ve got an LXC container running and...

I am new to PVE and would like to install it on my barebone PC Shuttle DS10U. The device has two LAN ports and - as usual - with one MAC address each. But during the setup of Proxmox is always displayed only one MAC address. Even when the LAN cable is plugged into the port of the other. This is...

Good morning, I am looking for a network card to install to my proxmox server. After investigating, the realtek NICs give a lot of problems to install in proxmox, so I don't know what network cards I could install in my server. I currently have an AMD Ryzen 5 5600G processor, running...

I did several proxmox installations on various hardware. But this one's puzzling me. It's a quite simple setup: 32 GB RAM, ZFS-RAID on a six core CPU. Onboard are two Intel e1000e NICs. Under a Debian live installation (bullseye) they work fine. But the proxmox ISO has no luck. In Debug...

TL;DR I can ping 1.1.1.1, but I cannot ping the router on the same network, nor access the GUI from another computer. I’ve changed NIC’s before, when I swapped motherboards, so I have solved this issue before, but I’m completely stumped with how my setup is currently broken. I know there is an...

Hello! For a project we have a UniFi 24 Ports switch (2nd gen), we also have a Proxmox cluster. We configured the UniFi switch to mirror the uplink (trunk) port to the UniFi UDM. When physically connecting a laptop and Wireshark to this mirror port, we can see all traffic (from ALL vlan's)...

We installed ProxMox with the network card present on our server a dual port sfp card but need ehternet ports to continue. We therefore installed a network card with 4 ethernet ports after installing proxmox ve 7.2 The card is not automatically getting an ip and I dont remember if i should go...

im trying to setup a network bridge between my 10gbit cards so my computer has a network card with 2 10gbit ports that i want to set up as a bridge in windows to effectively get "20gbit" between proxmox and my pc. proxmox server is behind my computer. so i have 2 10gbit in main pc going to...

I just installed a SUPERMICRO AOC-STGN-i2S in my 5018D-FN4T. PCI passthrough is working fine for a VM. 1. How do I add this interface to pve with the system already setup? I know I can init the lines for a new iface in /network/interfaces, but there has to be more to it than that. I'm not...

Servus zusammen, ich habe bei meinen VM's ein Problem mit der stabilität im ausgehenden Netzwerk Traffic. Solange nur ein VM aktiv ist hält sich der Traffic stabil, in dem Moment in dem aber auf dem Host System gearbeitet wird oder eine zweite VM zugeschaltet wird, bricht der Traffic alle paar...

Hello I've got a 4 hosts cluster (3 with exactly the same hardware, and 1 with another). I've launched an upgrade on one of my host a few hours ago (1 of the 3 same). No problem during the upgrade. At reboot, no network. I found that my nic names have changed (for a part of them). After looking...
