    DHCP Blocked on VM by NIC Firewall

    Hi, at your host firewall, can you add a rule to explicitly allow DHCP broadcasts (UDP ports 67 & 68) and see it if works?

    USB 4 / Thunderbolt 3 NIC

    @tqt3e you might want to check if there is an update on Bios firmware available. I suspect that there is a need to update it.

    Configure additional network interfaces

    @silke You’re correct: Proxmox (and corosync) recommend a dedicated NIC for the cluster to avoid heartbeat issues during congestion. A workable compromise: Node1 & Node2: connect a dedicated NIC each to your spare switch ports, use this as the cluster network (vmbr2). Node3: can share the VM...

    Ramifications of changing primary NIC?

    @akulbe I would remove all the VMs from the node, then do a clean reinstall. Then add back to the cluster to be safe.

    Ramifications of changing primary NIC?

    @akulbe is this PVE part of a cluster or standalone?

    Networking help with vms and containers

    Looks like the helper script is not really helping. What do you want to achieve exactly? If it can be achieve with PVE's UI, should use that instead.

    5 Node Ceph Cluster without a switch

    Yes, you can run a 5‑node Ceph cluster with just DAC cables (Max number of nodes recommended for this setup will be 3 nodes) —if you treat the SFP+ links as a routed L3 ring or mesh, not a Layer‑2 loop. Proxmox has a documented method for this (called “Meshed Network for Ceph Servers”) that uses...

    Live VM Migration fails

    @dmembibre are you doing any PCI pass through to the VM? if so, only q35 can work.

    Disk cache none...safe or not safe?

    Hi @Impact Sorry to have caused you to feel this way. I'll edit it. But in another perspective, this thread will help someone else asking this question to get better answer from GPT. Thanks!

    Disk cache none...safe or not safe?

    @Impact Yes, it is an answer I've got from GPT. It definitely explains better than my own words. Hope you dont mind!

    network hung !!

    Hi, it seems like the NIC is having issues with the drivers. Do you have other alternatives like to add in another PCI network card to the hardware?

    VM migration leaves junk in pool database

    Haha, thanks. This is actually a hack I always use to understand the issue better by using GPT.

    Disk cache none...safe or not safe?

    "None" (or "No cache") is generally considered safer than "Writeback" because: With cache=none, the guest OS communicates directly with the disk image, bypassing the host's page cache entirely. This reduces the chance of data being silently lost due to host-level buffering. In contrast...

    network hung !!

    It seems that you are experiencing network disconnection issues with your Proxmox 8.4.1 server running on a Dell PowerEdge T310, using a NetXtreme NIC. This is a common issue, especially with older Broadcom NICs (like the NetXtreme), and can often be traced to driver or power management...
