  1. [TUTORIAL] HOWTO: Proxmox host serial console (UEFI-boot), useful when passthrough your only GPU

    The original ideas are from: https://forum.proxmox.com/threads/serial-port-on-host-to-proxmox-console.81045/ https://help.ubuntu.com/community/SerialConsoleHowto https://tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-kernel.html...
  2. update-initramfs -u -k still updates both images

    Hello, 1. Because I passthrough the only graphics card, once the PVE gets to "Reading all physical volumes...", I no longer can use the console. If I make some change that lock myself out of web interface (for example, change network config), I guess that I have no way to get into the system...
  3. Can Proxmox bridge two NICs (one has internet access, one does not)

    Due to some restrictions, I have to use two NICs on my Proxmox node in the following way: For example: NIC1: 10.10.10.xxx, just one IP assigned by the facility to the Proxmox Node, able to access internet via their firewall NIC2: 192.168.150.xxx, connected to my own router (192.168.150.1) Can...

  5. [SOLVED] Accidentally deleted root=ZFS=rpool in kernel/cmdline and boot hangs

    Hello, Urgently need help. I have research work data on it:oops: Story: My GPU passthrough has been working well on both 6.2.55 and 65. Because I used update-initramfs -u -k all, both .55 and .65 has GPU frame buffer disable thus no host display out. I was trying to reverse GPU passthrough...
  6. Ask for best practice allowing host CLI diagnose if only one GPU that is passed

    Hi all, I had some issue to connect to my proxmox sever which does not have IPMI (or iKVM). It is build on a Threadripper workstation with MSI TRX40 motherboard. I fixed the issue, which is not related to the proxmox. That lead me thinking: Since my only GPU has been passthrough, the frame...
  7. ZFS with no log and cache

    Hi all, I have created two zfs pools with the simplest command: zpool create <pool> <device> at the begining. It seems have no log (aka zil or slog) and cache. I believe I did turn on lz4 compression for all three. My question is: in my case, do I need log or cache for each pool? zpool status...

  9. [SOLVED] Large Variation in VM Performance

    Update: I am chasing the ghost here. I have set high performance in Win10 new setting menu in VM412. But the old style power plan (now called additional power plan setting) is still on balanced. Duh. Now VM412's bench are similar to VM500. The reason why VM500 has good benchmarks at the...

  11. Threadripper Proxmox build, need suggestions

    [cross posted on STH] I work in a research lab that we recently purchased a Threadripper 3970x workstation from a System Integrator. It is a better better deal than Dell-Intel, which would have cost us twice as much. The role is to run Proxmox as base Hypervisor and run multiple Windows and...
  12. Passthrough nvme SSD on a quad SSD PCIE card

    Hi, I have a workstation with MSI TRX40 motherboad, which comes with a Dual SSD PCIE card to allow two SSDs on the card to split a PCIE x16 lane. Quad card can also be purchased. I was wondering how proxmox will see them when passing through nvme SSDs on the Dual or Quad card. Will they behave...
