network adapter

Hi Guys! Some of my VM lose their network connections on random time and when I check the issue, It leads to turning off and on the network interface to solve the problem. Proxmox Version are 7.4.3 and 8.0.4 on different networks. Any idea how to solve the issue?

I set a dns name with duck dns to my ip address and it worked fine a while them I could not got to the web ui anymore. I could not ssh to the server either. I accessed directly the server and I discover that my two network interfaces where missing and vmbr is still there but gave an error as...

Hi everyone, I've seen many with similar issues, but no resolution that I could apply (at least I wasn't able to). I have a test PC that was running fine with PVE7. After the upgrade to PVE8, the network connection would stop after a few hours after reboot. The screen shows loads of messages...

Hi I'm trying to use Proxmox with the debian bookworm cloud image and cloud-init. But when I start the vm it gets stuck on boot when it checks that it has a network connection Job systemd-networkd-wait-online.service/start running (#s / no limit) for about 2 minutes. It seems Debian bookworm...

Hi there, I've tried to do as much reading up as I could on this before posting. I got the main takeaway that for debian 12 the AX210 was included so some of the issues I read for earlier versions don't apply now. I've struggling to get the interface to work with similar messages from...

Hey all, I have a DL gen10 server that I installed an HPE dual 10Gb 560FLR-SFP+ Adapter into. I've found that it will not pass bond0/LACP communication. An Intel X520-T2 with the same interface bond0/LACP config connects without issue. The switch shows LACP is communicating/connected. Does...

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...

So, here is the thing. I have a dual SFP+ NIC that works well. I also wanted to place a 2.5Gbe Quad card into my proxmox machine. I am simply trying to do a Linux bridge within proxmox. The card is seen but won't become active. I tried a dual 10Gbe card and it was seen and would become active...

I'm trying to use a network card on my server, I've tried some configurations but without success, would anyone have any guidance on this? -network card does not appear in IP link Proxmox: 7.4-3 I tried this and it didn't work: $modprobe -r ixgbe $modprobe ixgbe allow_unsupported_sft=1 $...

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...

Hi, I have additional ip on Hetzner, but I can't figure it out how to use it, all my attempts have failed. Below I have attached my most successful host and virtual machine config. From a virtual machine, I can ping 173.1.2.98, but that's all. Thank you. Main ip Hetzner info: Gateway...

Hi, While investigating stability issues with my Proxmox installation, I have looked into the Realtek R8125B interface I use. It seems to use the wrong driver. My UniFi switch often “auto-negotiates“ the ethernet speed on the switch port to Fast Ethernet (10/100mbit) instead of 1 gigabit (max...

Hi everyone, I've been doodling around with Proxmox for a couple of months and, sadly, I've recently lost the onboard Ethernet port on the PC I'm using as a server, the same I used for the initial configuration. I have handy a USB to Ethernet adapter which is being detected via lsusb but I...

Hi According to the documentation, Proxmox uses tap devices (layer-2 devices which accept Ethernet frames) along the virtual switch (Vmbr0). I am not understanding why vmbr0 has an IP address, what is it needed for? and what is it used for? The code below is taken from the documentation for the...

Hello! I upgraded the kernel to 6.1. After installing a PTR-FU network card (RTL8125B) my main network card stops linking once the kernal boots and it is not reachable by the network, however it has the same IP as before. Any idea what it could be? Do you know if PTR-FU (RTL8125B) is compatible...

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...

Hallo Community, ich bin warscheinlich der erste mit den problemen. Ich habe schon stunden damit verbracht eine Lösung aber die haben immer damit geändet das ich mich nicht mehr mit meinem Server verbinden konnte weshalb ich den dann neu aufsetzen musste oder die ändern einfach nichts bewirken...

Hello everyone, I installed Proxmox on a MacPro 2013. Because logically no further hard disks fit into these and I didn't want to spend any more money on an external hard disk housing with Raid function. I took my Fujitsu Esprimo P7936 and plugged in all my hard drives and connected them to a...

I have two NIC cards: one is connected to the internet, the other is connected to an internal network. I am able to administrate the Proxmox instance just fine from the internal IP/NIC. Is there a way to move the external IP from the host's external interface to a single VM on `vmbr0`?

I just created two VMs and for some reason they don't seem to get IP assigned from the DHCP server. When I give them static IP it does work. I just go into Proxmox fyi. So there must've been something I missed configured or haven't configured at all. Thank you.
