network config

Hello everyone, I hope you are good, I am a Linux sysadmin, who are using Proxmox in DEV env after having used VMWare, and I came across this strange issue, which is having 3 Proxmox bare metal hypervisors running VMs and VM's can't connect to the internet but the hypervisors yes. I have the...

Hi All - I am trying to use the HTTP API to change the vlan tag on net0 for a VM. I'm banging my head against the wall trying to get this seemingly simple command to work. I'm hoping someone has seen this issue and can help out. Example curl command: curl -X PUT -H 'Authorization...

Here's what I did. When I first set up the 3-node cluster I only had 1 cable for the storage network, ie. where each host is connected 10Gb/s to a switch so they can use a shared storage scheme (Ceph - to which I'm fairly new and just learning) This week we got the extra cables ordered (because...

Hi Folks, I have performance issue with a 3 node cluster PVE 8.4 (all updated installed) on network side Hosts are using Intel 710QA2 adapter which are 40Gb QSFP+ 2 port nic. connected through a 5700 HPE switch which obviously support 40Gb connection. Firmware of the card has been updated to...

Hello. I have started replicating data from 1 site to another for DR. At the corp office i have a layer 3 switch and have the ability to do vlans on both the firewall and router. At the Dr site - no. Because of this issue whenever I boot up the servers at the DR side I have to change there...

I installed Proxmox over Debian 12 so I could keep my Windows partition on the machine I'm running the server on. After I installed Proxmox my ethernet did not appear to work on the machine (only wifi worked, which is what I used when installing Proxmox over Debian 12, not sure if that has any...

Moin zusammen, aktuell setzen wir einen kleinen Proxmox-Cluster jeweils mit lokalem Storage via ZFS ein. Da die Hardware zur Reinvestition ansteht, plane ich einen neuen PVE-Cluster mit CEPH und habe dazu noch ein paar Fragen, die ich trotz Recherche hier und via Google nicht oder teilweise...

Hi, I recently started working with Proxmox and I'm trying to configure subnets using vlan. I have only one physical network card and I reach my proxmox on the 10.10.4.0/24 network. I would like to create VMs on a separate network like 172.16.240.0/24 so I went to see the documentation to...

Hi, I've recently started working with Proxmox and built a 3-node cluster. My nodes have the following addresses: node1 - 10.140.128.1/9 node2 - 10.140.128.3/9 node3 - 10.140.128.5/9 Additionally, I have a special subnet for VMs: 10.140.134.0/24. Currently, my network configuration looks like...

I shut down my proxmox server to install a new storage adapter in it in preparation of setting up a truenas core vm. In the bios I enabled pcie bifurcation to split one 16x slot into four x4 slots (and no other changes I can recall). The storage card currently has two pcie drives installed...

Hi, I have a proxmox host with the following network devices eno1 vmbr0 And multiple interfaces as per the VMs ( VMID ). Firewall is checked on the VMs, but no rules are active tapVMIDi0 fwbrVMIDi0 Now I have two questions, 1. If I need to check the tx/rx bytes of the whole host machine...

Trying to wrap my head around how to implement a PVLAN within Proxmox. The purpose would be microsegmentation, so that each VM could not talk to each other without going through the upstream L3 device that has the Promiscuous Port configuration defined. Short of creating a VLAN per VM, is...

Dear All, I can not update my PVE installation because I can not connect to proxmox. After I'm googling here and there, it seems like the problem is related to the realtek 8169 driver of my NIC. The problem is, every solution needs me to update and then install needed software/driver. But for...

Hi, we're building an 4 node PVE cluster with NVME Ceph storage. Available Nics: We have several nics available: Nic1: 2 x 10G + 2 x 1G Nic2: 2 x 10G Nic3: 2 x 100G Traffic/Networks: Now we need (I think) the following traffic separations: PVE Management PVE Cluster & Corosync Ceph (public)...

Hello all, iam completly new to proxmox I just installed it on a Dedicated Server and now I cant figure out how to proper setup the network. I have for now two public ipv4 adresses I can use. The first one is completly reserved for the proxmox host. The second public IP adress I want to point...

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...

I am struggling since days setting up a very simple network for a new PVE: 1 NIC 5 Public IP Addresses I want to use the first IP address (vmbr0) only for the PVE and the other four are by the VMs. These IP addresses will then be set in the network settings of the individual VMs. Result...

I have the networking running on a VM, so know that works, but using the same bridge on containers doesn't work. Not sure what I'm missing. Host network: auto lo iface lo inet loopback iface eno1 inet manual iface eno2 inet manual auto ens2f0 iface ens2f0 inet manual auto ens2f1 iface...

Good morning everyone, I am running into some issues with my ProxMox lab environment. I have a 4 Nic server running a handful of vm's and 1 container for testing, and I cant ping into the VM's, and can only ping out to specific machines that are not on the host. I have the 4 nic's in the server...
