  1. Database Server With vRack & Failover IPs

    HI, I'm struggling to get my head around H/A with OVH and vRack. I have a small database server I want to provide some redundancy too. I have three servers located in the same region and vRack configured with a subnet of IPs. Can someone give me an example of the networking? I was thinking I...
  2. [SOLVED] Reconnect Proxmox Backup Server to PVE Cluster

    Hi Everyone, My local Proxmox Backup Server stopped networking for some reason (possibly a driver issue?) while running as a VM under BHyve, so I issued a systemctl restart networking and things returned to normal. However, the Proxmox Virtual Environment cluster now shows the PBS repository as...
  3. PVE Cluster Service IP

    I would like to ask for a new feature: Service IP for a PVE cluster. I.e. the Proxmox cluster manager should be able to configure an IP address that is always active on one of the nodes (maybe the cluster leader). This would make it easier for automated tools to talk to the API. In case of a...
  4. Proxmox OPNsense und Hetzner

    Guten Abend alle zusammen, ich habe seit ein paar Tagen mit Mac Abuse Meldungen von Hetzner zu kämpfen. Komischerweise sind die Unerlaubten Mac Adressen die Hetzner mir in der Mail zugesendet hat, Mac Adressen die automatisch durch die OPnsense erstellt werden. (siehe Bild) Wisst ihr ob man das...
  5. iSCSI high network usage

    I mounted my synology nas via iSCSI and created a LVM on it and made it avaiable to my 3 nodes. One of those nodes is unused and is just there for quorum. On that node that runs no VMs I see really high transfer from my NAS to that proxmox instance (45MB/s continuously). Even after I remove...

  7. Option for double bastion Terraform setup?

    Hi, so due to security policies of my company, I am in need of a double bastion networking setup to connect to my VMs in Proxmox.

    Hi, I have a VM set up with cloud-init according to the instructions at https://pve.proxmox.com/wiki/Cloud-Init_Support using the Ubuntu Focal cloud image. This all worked flawlessly the first time I did it (thanks!). However, later I wanted to change the network configuration without...
  12. Basic networking question

    Hello, I am new to proxmox and trying to figure out why my VM can't communicate with the outside world. Here's a diagram of what I have put together: The node itself can communicate with internal IPs as well as the internet at large, but the VM can only communicate internally. I'm sure...

The image files are called vm-106-disk-0.raw and vm-106-disk-0.qcow2. Both are 200 GB in size and attached using VirtIO SCSI controller and...
  14. Displaying ip(s) of containers in web-ui

    Hi, I would have expected that the ip(s) of containers would be visible in the web-ui. This does not seem to be the case, why? It would be particularly helpful to see what ip was assigned to a container in the web-ui.
