    [SOLVED] IOMMU not enabled on HPE Z640 after following guide

    Have you tried this? Maybe you also have a known problem with HP and enabling interrupt remapping and/or IOMMU? As long as for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nnks "${d##*/}"; done. shows no multiple groups...

    PCI passthrough on Proxmox - HP PL DL380 G6

    D'après la documentation proxmox, on peut peut-être contourner le problème de interrupt remapping : If your system doesn't support interrupt remapping, you can allow unsafe interrupts with: echo "options vfio_iommu_type1 allow_unsafe_interrupts=1" >...

    PCI passthrough on Proxmox - HP PL DL380 G6

    I don't think that PCI passthrough will work for your system because interrupt remapping is broken. Maybe you can find a fix or work-around somewhere else in this forum, as more people are having this issue with HP systems. EDIT: Maybe this can help?

    with usb passthrough you can only passthrough single usb devices not the whole controller, for that you need to use pci(e) passthrough. please read the docs for pcie passthrough https://pve.proxmox.com/wiki/PCI(e)_Passthrough
