Every time i try and create a new VM and add my video card to it i get the following error

 

I have already tried moving the GPU to a new slot so it's out of the other devices iommu group. I also enabled PCIe ACS over ride and that did not do anything. Though im not 100% sure it's working. Every time i go into my VM manager im greeted with a

You must reboot for changes to take effect

so i cant be sure that its working even though i've rebooted several times.

 

Any help would be appreciated

yes your gpu is in iommu group 1 which has alot of devices in it and must be split up into its own group for it to work,

 

If you are not sure if acs override is working then goto the main tab on gui and click flash.

Then scroll down to

 

it should have the default part like this

 

label unRAID OS
  menu default
  kernel /bzimage
  append pcie_acs_override=downstream  initrd=/bzroot

 

so if this part says

append initrd=/bzroot  and not  append pcie_acs_override=downstream  initrd=/bzroot    then edit  it manually then reboot server and check

again,,, it should stay.

Seems like every device in my system is getting lumped into group one.

 

The HP Ethernet controller is at the bottom of the motherboard and is still being grouped with the others.

 

How can i break them out? I have already tried moving the card.

Using the append pcie_acs_override=downstream  initrd=/bzroot  is the only way i know of.

Did you check that is in your syslinux config file after reboot?

That was in the config but i found this in another thread

pci-stub.ids=8086:10bc

I added my own device ID, booted the system in non GUI mode even though i had UNRAID using the onboard GPU and im able to make the VM and pass the GPU though!

Sorry unfortunately this issue has returned.

 

This was the bit of code i used previously to get it to work

 

append pcie_acs_override=downstream pci-stub.ids=1002:6798 initrd=/bzroot

 

However i needed to add a USB PCI card to pass through as well. It was not showing up as available to pass to i added this along with the top code in the config

 

append pci-stub.ids=1912:0014 initrd=/bzroot,/bzroot-gui

 

Now the GPU will no longer pass with the following error again. Any ideas?

Oh and unfortunately i need the USB pci adapter. I have 3 usb items with the same manufacturer Only one of them works if i use the normal passthrough method on them.

 

I got it with some tinkering and reading some other threads!!!

 

Appended it from 2 lines to 1

 

append pcie_acs_override=downstream pci-stub.ids=1002:6798,1912:0014 initrd=/bzroot

 

it's all good
