leesteken, you are a god amongst men! I have iommu groups coming up now!!!!

I would be really surprised if vt-d/iommu didn't work on this board and CPU as advertised, and it is enterprise gear. cat /proc/cmdline initrd=\EFI\proxmox\5.13.19-2-pve\initrd.img-5.13.19-2-pve root=ZFS=rpool/ROOT/pve-1 boot=zfs

Hey guys, second run at trying to get PCI passthrough working within proxmox, Server - 2630L v4, supermicro x10srl-f, Quadro T400 and Intel 4x1gbe nic GRUB If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this...

Meaning that if I do it this way the GUI will no longer work or do you mean if I have a physical screen connected I won't see the Host at boot up?

So further update. Running the codes below has allowed the VM to run and no errors in syslog however guest agent is not running and it has been setup so I cant RDC into the vm echo 0 > /sys/class/vtconsole/vtcon0/bind echo 0 > /sys/class/vtconsole/vtcon1/bind echo efi-framebuffer.0 >...

So I have been doing research and further found that the problem may be with the 1st PCIe port on x99 motherboards. It seems that the pci device isn't unbinding from the host to passthrough to the guest. Is there a practical way to test this? I do have a secondary GPU as a quick test for another...

All good! here you go root@Homestead:~# for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done IOMMU group 0 ff:0b.0 System peripheral [0880]: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 R3 QPI Link 0...

Sorry, that was actually my fault, I removed it in hopes to reduce the local storage filling problem. Here it is also I attached a notes file because the text was too long for the text box here. agent: 1 balloon: 1024 bios: ovmf boot: order=scsi0;net0 cores: 4 cpu: host,hidden=1,flags=+pcid...

I did run the update for grub, thanks for the reminder and here is the result! root@Homestead:~# cat /etc/pve/qemu-server/103.conf agent: 1 balloon: 1024 bios: ovmf boot: order=scsi0;net0 cores: 4 cpu: host,hidden=1,flags=+pcid machine: pc-q35-6.0 memory: 8192 name: Windows-Tester-1 net0...

So cleared the line pcie_acs_override=downstream,multifunction from grub and then used nano /etc/pve/qemu-server/ and the result came back saying this is a directory and the area is blank

Well then I am stuck, I have no clue what Im missing here, the only thing I can think of is that it's some kind of hardware issue but this is obviously not my area of expertise. Also, thank you for all the help so far!

So I've been thinking and wild question here, my server won't boot without a GPU installed, would this create an issue when PCI passthrough is enabled with a permissions or required hardware level problem?

Also a fun new addition to this problem is that the kern.log is 17 gb and my local fold is now full. Which I do not know which files I can and should clear and how to do it via SSH because I can no longer Gui my way in

hey so here is the group list. Im not sure if I don't know what I am doing but the VGA 02.00.0 in group 30 I think is the graphics card because that is the correct number for it I had to use find sys/kernel/iommu_groups as dmesg | grep iommu did not produce a result /sys/kernel/iommu_groups/17...

Same version of bios just wanted to see if there was a sticking point somewhere. Also how would I check iommu groups? I have pulled it up before and seen the lines of code but how do you determine groups?

So Update: I switched to bios 2 as the motherboard supports it, the VM boots but the qemu/guest agent doesn't work for RDC. I'm not sure if it's hanging somewhere in the boot or if this is a side effect of something else altogether. Additionally, I noticed that an option of ACS from bios level...

Yes it is the only gpu in the system, I get a Qemu exited with code 1. also I added that line of code to grub and still the same problem. Sidenote if its important the Vm is windows based and I followed this guide: https://www.youtube.com/watch?v=fgx3NMk6F54&t=453s - Clearly not well enough.

This is what happens when I try to check iommu. root@Homestead:~# dmesg | grep -e DMAR -e IOMMU root@Homestead:~# When I try to initialize the VM the will attempt to start then the log comes back with a error - and hard freezes the VM to the point I have to restart the entire node. Here is...

I have seen the many threads but I promise I'm a special case here. I have Proxmox VE installed with ubuntu and windows VM which I have two different tasks. Long story short I can physically see my graphics card as a passthrough option but once I go to initialize the VM doesn't work. I have...
