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...

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...

Hello all! I'll preface this by saying I've already looked up many resources on this thread, and google, but I can't seem to get IPv6 to work correctly. I used to have everything setup correctly in my home network (IPv6 wise), but I now have a Unifi router, and I just can't seem to get IPv6 to...

Hello, I have four Proxmox servers, updated to the latest verion. Each have their network configured in the same fashion, with multiple network cards, which are either not getting an IPv4, getting one by DHCP or one, vmbr0, having a static assignment. On vmbr0, each server has its own IP within...

I'm in need of some help from some of the seasoned professionals out there. I'm setting up a 5-node cluster with Ceph that will run around 30-40 VMs. Each node has two 4-port 10G NICs. I'm going to use LACP to bond one port from each NIC to create four connections on each server. However, this...

When importing an Ubuntu cloudimage VM from VMware I noticed that the networkinterface name has changed, and potentially happens again in the future. So I want to make it static inside the VM. Context is that the VM originally is configured by VMWare's Cloud-init approach (...

My server was struck by lightning..... Ouch. Since then I have been busy moving and such. I have just powered on my Supermicro X10SDV-12C+-TLN4F system after many months. After loading the new system I was unable to access the server via any browser except an old Windows 7 Pro OS which had an...

Hey guys, I'm looking to port forward my proxmox and access via WAN so I can access Kali VM. Can anyone provide any guides I can use to do so? Everywhere I've looked I haven't found a sold or updated tutorial on doing so, I have an Arris BGW320 router Thanks in advance!

My Proxmox host has great network connectivity. Before I rebooted it, my LCXs and a single Win VM all had similar. After a recent update and reboot, my containers and VM are all under 1 Mbps. /etc/network/interfaces auto lo iface lo inet loopback iface enp2s0f0np0 inet manual auto vmbr0 iface...

Fresh install of Proxmox (version 8.3.5) on a Dell T620 with 256 GB of Memory on a 1TB SSD. Boot sequence is great and I am able to reach the Proxmox web GUI, but after some amount of time initially it was 30ish minutes now it seems to get to about 6-12 hrs then the ethernet connection is...

Hello, I'm new here and, as expected, I have a question. :-) Is it possible to tag the Proxmox host interface AND the guest interface? Example: The Proxmox server has only one network connection (Linux Bridge), which is tagged with VLAN ID 120. On the guest system (Debian), three virtual...
