I want to use SDN's DHCP to assign IP addresses to the virtual machine's tap device, but I find the dnsmasq config file which managed by PVE itself has this optiondhcp-ignore=tag:!know. So if the MAC address is not in the list of addresses assigned by PVE, the DHCP server can only receive the...

I have a persistent issue where a windows VM (only one I know of with this issue) has a persistent problem of the network speed dropping after a period of time. I'm using VirtIO with multiqueue and I get 10Gb speeds as expected, but after a few hours, the speed seems to drop to become capped at...

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...

My GPU is really loud and as this is supposed to be a server I do not need it. But after I unplugged it, I couldn‘t connect to the WebGUI, so I plugged it back in and everything worked again. And yes, I know about network names changing when adding or removing PCIe devices, but that doesn‘t...

We are testing the live migration on 8.3.0 between both clusters and we're running into one issue we can't seem to find a good resolution to. Whenever we migrate a machine it can't pull networking because for some reason the arp table on the source is still holding on to the mac address. We've...

Hello, I want to confirm if my current Proxmox networking setup is configured correctly and working as expected. Here's the scenario: I have a Proxmox server with a public IP assigned (e.g., 103.xxx.xxx.244) on vmbr0. My organization uses a Sophos firewall for routing and NAT. The firewall...

Hi, ich habe Opnsense auf Proxmox laufen und zwei Interfaces auf dem Server: WAN (eth01 - vmbr0) und LAN1 (eth02 - vmbr1). Über Opnsense habe ich mehrere VLANs (LAN1 als Parent) konfiguriert sodass mein Switch der über LAN angeschlossen ist, Geräte zuweisen kann. Ich habe aber noch weitere...

Hey, trying to figure this out and getting deeper. New install Pmox and able to upgrade everything before deploying VMs. Initial VMs actually connected fine but suddenly do not. Only had one other and all subsequent deployments without pci passthrough are failing on the vmbrs. Proxmox Host is...

HI, I have a motherboard with 2 NICs on it. a 2.5gb and a 1gb. I have been using the 1gb as my primary NIC since I built the machine and due to the nature of my setup was using the 2.5gb as a way to pass a 2.5 connection between some of my VMs and my PC. I have switched my networking around and...

So it has been a **long** time since I've done anything with the networking on my proxmox ve setup. For reasons that I have no recollection of (other than maybe 'sounds cool!') I went with openvswitch. I now need to do some vlan work. When I open /etc/network/interfaces the first thing I...

EDIT: SOLVED. So apparently my 10Gbe sfp on my switch for that subnet crapped out. Lesson learned to keep a couple extra on hand. now to look into if there ways to monitor that it was failing. I did notice later last night when working on one vm that things were getting slower to respond on my...

i read some other threads about this error already, just wanted to make sure what my options are. we have a pve-cluster setup with 9 nodes, all with identical hardware. we now wanted to scale out and ordered identical hardware, only difference we got delivered a rev 1.3 of the mainboard. for...

I have a ProxMox server (8.2.2) and a fresh install of Windows Server 2022 that I ran through Sysprep with all the VirtIO drivers installed and made into a Template. I have deployed the template and set up a new server from it. For some reason the VirtIO NIC won't identify my network, but if I...
