Hi all, is it correct that by default Proxmox 9 in a 3 node cluster configuration with CEPH for VM migration use VMBR0 network? Current node network config does use a separate network for CEPH Cluster (10.10.10.x/24), CEPH Public (10.10.20.x/24), COROSYNC (172.16.1.x/24) and VMBR0...

Hello! Recently decided to build out a more proper homelab and started experimenting with Proxmox; apologies ahead of time if I missed something basic, still very much a beginner. Stumbled across an interesting issue where I am unable to reach services running on a VM from my local network but...

Hello all, I was recently testing VM to VM bandwidth/speed on various machines in my homelab. I was doing these tests with iperf3 from within several VMs because I was not quite getting 25gb speeds accross my network. I eventually got to the point where I was looking at both the Proxmox BIOS...

Hi, I have an Ubuntu 24.04 VM running on Proxmox with a Virtio network device. Network performance on this VM is extremely slow compared to other VMs on the same host. Details: Proxmox VE 8.x Guest: Ubuntu 24.04 LTS Network: Virtio (paravirtualized) MTU currently 1500 (tried raising to 6000...

Please delete this tread. As usual, my mistake. Was re-using a LAN IP address I had used before which was part of a firewall rule to block outbound connections! I could ping, but tcp was blocked so it was a little hard to diagnose. ______

Hi, Sorry since I'm a noob I should probably not use that kind of setup but either way. All was working fine on my old HPe G10 blade server BL460c But just after upgrading to the new kernel update 6.14.11-2, it seems to goes to shit. No network connection available remotely since then during...

Hallo liebe Proxmox Community, ich habe aktuell folgendes Setup: Dedicated Server bei Hetzner (AX41-NVMe) Der Server ist öffentlich nicht erreichbar, sondern ausschließlich über einen IPSec-Tunnel angebunden (verbunden mit einem Linux-Cloud-Server → daher privates Netz). Netzwerkübersicht...

Once upon a time I successfully upgraded several Proxmox pve nodes from version 7 -> 8 (or was it 6 -> 7) being lazy and since it didn't seem to cause me any problems I didn't do a widely publicized step of, I believe if memory serves, adding source /etc/network/interfaces.d/* to /etc/network I...

Am new to proxmox so sorry if i am being dumb. I am trying to setup my homelab the way i want. Being curious about all the things to offer, I saw the proxmox helper scripts (just for clarity - https://community-scripts.github.io/ProxmoxVE/) and wanted to try different things on it. Now I have...

Hi, I'm migrating from HyperV to Proxmox VE 9, I've made the needed setup and have two bridges configured. i can reach the management interface fine on the ip's set on the bridges. my first migration is proxmox pmg, the vm starts fine, i can log in on the console. but it is unreachable from...

I am running PBS as a VM on the same Proxmox host where I back up LXC containers and VMs. Backups usually work, but sometimes they fail with errors like: catalog upload error - pipelined request failed: connection closed because of a broken pipe Error: error at...

Hi everyone, I have a supermicro server as a video recording server and recently migrated to Proxmox from ESXI, the network connections on server are as below: Nic0 connected to switch x (HP aruba 2930) and Nic1 connected to switch Y same brand and model. I have an issue in redundancy of this...

Hi I am trying to create an test proxmox cluster on openstack. It is going rather well until the part where I want the VM-s to access the network. In Openstack I have added a port with an IP to my proxmox hosts and also modifed allowed_addresses parameter, where Ive defined some IP-s for test...

I'm trying to figure out why on an older debian LXC (now version 12, but it has had atleast 2 major updates) the network.service comes back failed after bootup ug 08 10:34:24 metricsbox systemd[1]: Starting networking.service - Raise network interfaces... Aug 08 10:34:24 metricsbox...

Hello all, I just set up a fresh install of proxmox on a Dell 3040m. I am able to connect to the server from my local network. Once logged in, I try to install Debian LXC for a helper script, and I get curl: (6) Could not resolve host: raw.githubusercontent.com. I have then tried to ping other...

Hi! I write this post as a last resort. I'm trying to get a quad port RTL8125BG based network card I got for cheap to work on Proxmox VE, or really any other Linux OS. The network card works perfectly on Windows (Bare Metal), but when I try to run it in Proxmox VE (and I also tried Fedora bare...

Hi, I am in the middle of configuring the master node for my cluster, which is responsible for the whole homelab network handling. I was able to configure the following services: - pfSense as VM, uses 2 out of the 4 PCIe, bridged interfaces (vmbr1 from enp1s0f0 for WAN, vmbr2 from enp1s0f1 for...

Hey everyone, I'm running into a bit of a snag here. I've got three identical Supermicro servers, and after a fresh install of PVE 8.1.4 on all of them, the networking service just won't kick in when they boot up. I've attached the log for the networking service so you can see what's going on...

Hi I am trying to configure Proxmox VE using only netplan, as it is easier to generate yaml config using ansible, than the weird format of /etc/network/interfaces. We have stumbled onto something interesting. Proxmox gets data from /etc/network/interfaces file. So we don't have that file...
