also on cpu type host I get alot of these warnings/errors [11033.060489] SVM: kvm [46481]: vcpu0, guest rIP: 0xfffff87239a02ae9 unimplemented wrmsr: 0xc0010115 data 0x0

Hi. Previously had guest set up with cpu host,hidden=1 flags but after latest round of gpu (passthrough nvidia gpu) driver upgrades, win11 upgrades and proxmox upgrades I am getting 8 fps in games and very unstable os performance On a whim I changed cpu type to KVM64 and everything got much...

Sort for the slow feedback - your suggestion seems to have worked

Hi. on AMD platform - W11 guest - trying to passthrough USB - used to work a few proxmox versions ago - not sure where to start looking 0b:00.3 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller [1022:149c] (prog-if 30 [XHCI]) Subsystem: Gigabyte...

cool. I'll try that

I am passing through a whole controller 0b:00. But I need to prevent drivers from loading on host (I think - kinda like you do for GPU passthrough). If something is plugged into this port when I try to load VM it fails. So I have to disconnect whatever is connected to this port/controller then...

Hi. So I have a usb hub that I want to pass throught to a vm. If I plug the hub in or reboot the host with it the host detects it and loads drivers and PREVENTS vm from starting. Is there a way that I can blacklist this usb port / driver in host to prevent this scenario Thanks

You were right. BUT ncdu -x did not show the offending directory. On a hunch I unmounted my zfs pool only to find 50gb direectory in the zfs pool mount directory. Must have been written when the pool was unmounted. So my question is - how do you prevent writting happening to this zfs...

Hi. This filesystem mounted on / is showing 74G (df -h /) used even though ncdu / only shows 20 GB of disk usage Anyone can help?

Hi. Hoping someone can assist. I am trying to pass through this webcam to an ubuntu vm. I have tried passing through the device via usb as host and device. I have tried passing through the entire usb controller as a pci device. v4l is installed /dev/video0 /dev/video1 /dev/video2...

So some more testing. I removed all the driver and vfio specific config. When proxmox boots it displays the text console. At this point I can change drivers (from nouveau to vfio-pci at will) with no problem. However when I launch the windows 10 vm - it launches correctly and the GTX 2080 super...

Hi. I tried all the suggestions with limited success - every now and then something would work and the console output would come back after unbinding the vfio driver, but the behaviour is not consistent. I also forgot to state that my GPU is in PCI slot 2 - if this makes any difference and I...

Yes I did this - and lspci shows kernel driver - nouveau. Then I run the VM and vfio-pci is bound. When I run that reset code, the kernel driver is still vfio-pci and I dont see output. How do I get the nouveau driver back - I think that is the key.

Perhaps there is a command line that I can use to reset the card and force it to use a different driver like nouveau?

Hi. I have been searching for a solution to this use case - at one time this did work but after a few updates to proxmox something changed. As it stands I have my VM's working nicely with a single Nvidia GPU passed through. My GRUB conf line is GRUB_CMDLINE_LINUX_DEFAULT="amd_iommu=on...
