Devices in the same group can pass information to each other without the IOMMU noticing. 2 slot To have separate IOMMU groups, your processor needs to have support for a feature called ACS (Access Control Services). So I just passed the whole group through. Even though you are root within the Docker container, using an unprivileged LXC container means that you are not subject to root's normal full access rights, thus the root user needs also be a member of the groups of the GPU devices. It does not belong to any of the groups. Reload to refresh your session. 2 nvme usually runs directly to the CPU, as well as some USB ports; you also shouldn't need a powered riser for an x16 card in an x16@4 slot, since the first three pins are those providing power and the spec However, my Ryzen ASUS PRIME X370-PRO motherboard has an odd arrangement of IOMMU groups and some of the PCI devices I want to passthrough are in shared groups. Maybe the manufacturer patched better IOMMU groups with later firmware versions 3. with the current Setup, whenever I start the VM( click on the start button) the whole server crash, with no sign, I see no changes on the proxmox Prompt, but the VM is not pingable anymore and Web-UI get unreachable, but when I connect a monitor the server I could see the Proxmox logging prompt (unfortunatelyI got now keyboard to do anything on the physical Hello, I am trying to separate the IOMMU in a new TrueNas Scale bare metal build. #Change "GRUB_CMDLINE_LINUX_DEFAULT=" to this line below exactly GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on" #Run the command update-grub to finalize changes update-grub. 0 VGA compatible controller [0300]: Intel Corporation CoffeeLake-S GT2 [UHD Graphics 630] [8086:3e92] Make So I compared iommu groups with and without pcie_acs_override=downstream,multifunction and they are identical, so it looks like it's unable to split anything on this system.
