  1. Dlink DUB-E250 2.5Gbps ethernet adapter reports no auto-negotiation and only half duplex?

    Hi All, Thought I'd try a couple of Dlink DUB-250 USB 2.5Gbps ethernet adapters (on two different proxmox nodes) but both only seem to connect at half duplex and both report auto-negotiation is not supported/enabled yet the dlink website suggests they should support this...
  2. External Metrics dictionary and VM disk size/usage?

    Hi There, Is there a dictionary which defines the external metrics (and their meaning) that PVE pushes out to (for example) InfluxDB? For example, It's not clear to me how I'd get the VM disk size (and ideally usage but I suspect this is not possible from the metrics alone?) for the disk...
  3. Comet Lake NUC (NUC10i5FNH / NUC10i7FNH) gvt-g support?

    Hi Guys, I currently have a Coffee Lake NUC (NUC8i5BEH) where I use gvt-g for virtual GPUs for some ubuntu VMs (mainly for Intel QuickSync) and wondered whether anyone had tried this on the Comet Lake NUCs (either NUC10i5FNH or NUC10i7FNH) as thinking about buying one of those... According to...
  4. Full clone feature is not supported for drive 'efidisk0' (500)?

    Hi There, When I try to clone an existing VM from the (not-current/not-latest) snapshot, I get the following error (with the error seemingly randomly either related to scsi0 or efidisk0)? Is this expected or a bug? The configuration of the source VM being cloned is as follows...
  5. NoVNC VM console graphics corruption (Default VGA)

    I'm running a couple of Ubuntu 18.04.4 server VMs. The VMs run fine but when I try to view the VM using the "NoVNC console", I get the attached screen corruption? When starting the VM, the "Proxmox" splashscreen is shown fine in the console, but as soon as the VM commences boot, the display is...
  6. Regular ZED messages in syslog?

    Hi There, I'm running latest pve and using ZFS replication between local-zfs on 2 nodes. Every time the replication runs it seems to output the following type of messages in syslog without any clear meaning what they are referring to or whether they are just unnecessary noise? Feb 28 07:29:01...
  7. Live Migration with GVT-g (mdev) passthrough device?

    Hi There, I currently have a 2-node Proxmox 6.1 cluster (3rd node is qdevice) where both nodes are the same hardware spec and support Intel GVT-g (mediated device) Passthrough. I know live migration between nodes is not possible with standard GPU device Passthrough but, if GVT-g enables the...
  8. Changing selected kernel for boot (systemd-boot) on headless PVE Host?

    Hi There, I currently have a 2-node PVE 6 cluster (and 3rd node QDevice), with the 2 nodes operating headless with PVE installed as ZFS on EFI (systemd-boot). If I want to test the new PVE Linux 5.3 kernel on one of the nodes, I understand that I just need to do: apt update && apt install...
  9. Local/Remote Snapshots of Physical PVE Host/Node (ZFS)?

    Hi There, I'm trying to figure out if there is an easy way to use the ZFS filesystem of the Physical PVE Node to make local/remote snapshots of the host filesystem? I know there is away to replicate local VM disks from local-zfs (Physical PVE Node 1) to local-zfs (Physical PVE Node 2) but...
  10. Replace/Clone cluster node SATA SSD to NVMe?

    Hi, I’m thinking of replacing the single SATA SSD (500GB Samsung 860 Evo) disk in one of my PVE6 cluster nodes with a 500GB Samsung 970 Evo Plus NVMe disk... Should this simply be a case of using clonezilla to clone the SATA SSD to the NVMe and then booting PVE6 from the NVMe or would there...
  11. Intel IGP (Gemini Lake) Passthrough (q35) fails to boot on Ubuntu 18.04.3 LTS – i915 conflict detected with stolen region

    Hi There, I currently have a headless Intel NUC7PJYH and can passthrough the Intel IGP to a VM running Ubuntu 18.04.3LTS as long as the machine type is set to “Default (i440fx)”. I don’t use the passthrough Intel IGP for graphics output, I just pass it through as a secondary graphics card (the...
  12. [SOLVED] Lots of "CPUx: Package temperature above threshold, cpu clock throttled" syslog entries?

    Hi There, I have a NUC8i5BEH (Intel Core i5-8259U CPU) node and noticed that my proxmox syslog (running Proxmox PVE 6 but also occured on PVE 5.4) often outputs the following set of critical errors throughout the day: 23/07/2019 23:26:56 crit pve-host1.local kern kernel...
  13. [SOLVED] Enabling IOMMU on PVE6 (zfs) compared to PVE5.4 (ext4)?

    Hi All, I did a clean install from Proxmox 5.4 (using single disk ext4) to Proxmox 6 (using single disk zfs) and notice that I don’t seem to be able to get IOMMU enabled under PVE6? I followed the following instructions (as I had with PVE5.4) but suspect that because I’m not booting zfs, it’s...
  14. Upgrade cluster node to Proxmox 6 (re-install) when already part of Proxmox 5.4 cluster?

    Hi, I currently have a Proxmox 5.4 homelab cluster (2 nodes + external qdevice) and plan to rebuild the cluster as Proxmox 6 via a complete re-install of each Node (since I want to move the underlying local storage to ZFS on UEFI). I’ve read the PVE6 upgrade guide...
  15. Online / Live Migration with ZFS-Replicated local VMs?

    Hi There, Is there a technical reason why Online / Live Migration of VMs that are replicated across local disks (from Node 1 local-zfs to Node 2 local-zfs) does not currently seem to be permitted? If this is not currently permitted / available, is it planned to be made available in Proxmox 6...
  16. HA Migration of VMs using local devices

    Hi There, I've seen this raised a couple of years back (https://forum.proxmox.com/threads/migrate-vm-with-local-devices.17369/#post-88296) and I'm wondering what is the best / recommended method for migrating a VM (with Intel IGP passthrough enabled) from one node to another? Currently, my VM...
  17. Proxmox USB/SD Card Boot Recommendations?

    In my home lab, I have 2 Intel NUCs (both only allow 1 * SSD and 1 * NVMe) and I’m currently booting them (UEFI) from the internal SSD. The 2 NUCs are setup in a cluster with an external qdevice for corosync quorum votes. I would like to use these internal SSDs as VM storage to maximise...
  18. Intel IGP Passthrough - Invalid PCI ROM header signature

    Hi There, Posting this more out of interest than an actual issue... I’m getting the following error in the Proxmox host syslog when starting a VM with IGP passthrough: Jun 8 16:08:51 pve-host1.local kernel: [309988.432878] vfio-pci 0000:00:02.0: Invalid PCI ROM header signature: expecting...
  19. Proxmox NFS Backup/Remote Snapshots

    Hi there, I currently have some VMs which are hosted on and run from a shared NFS share by the Proxmox hosts. I currently use Proxmox to backup (snapshot) these VMs back to the NFS share but this seems inefficient with the reads from NFS -> PVE host and writes back from PVE -> NFS host...
  20. Failed to add cluster node "401 No ticket"

    Can anyone help with the following error I'm getting after creating a cluster on a single node and attempting to add a second node to the cluster? I've created a cluster on the first PVE Node (call it NODE1) which has the following networks configured: DefaultLAN - 192.168.1.NODE1 ClusterHB...
