1x NVME for Cache + 1x NVME Passthrough configuration (SOLVED)


Recommended Posts

Hi,

 

I have a Gigabyte X570 AORUS MASTER with 3x NVME slots on board:

  • NVME 0: Used for a bare metal install of Win10
  • NVME 1: Used for a cache drive for Unraid
  • NVME 2: Not used for now

 

I successfully installed Win10 as a bare metal
and configured correctly the cache drive for Unraid.

 

But when I tried to passthrough the NVME 0 to Unraid to create a Win10 VM from the bare metal installation,
the cache drive disappears from Unraid.

 

I suspect that there is only one controller for the 3 NVME.
And that controller can only be affected either to Unraid or either to pass through a VM.

 

Is there a way to allocate the NVME 0 for the VM and the NVME 1 for the cache of Unraid ?

Just in case, here is my configuration.

As you can see the NVME have both the same ID but in different group:

...
IOMMU group 14:	[1987:5016] 01:00.0 Non-Volatile memory controller: Phison Electronics Corporation E16 PCIe4 NVMe Controller (rev 01)
...
IOMMU group 23:	[1987:5016] 04:00.0 Non-Volatile memory controller: Phison Electronics Corporation E16 PCIe4 NVMe Controller (rev 01)
...

 

So I updated the boot sequence:

kernel /bzimage
append pcie_acs_override=downstream,multifunction initrd=/bzroot vfio-pci.ids=1987:5016

Settings available for the VM:

USB Devices: 	
- Logitech Unifying Receiver (046d:c52b)
- Integrated Technology Express ITE Device(8595) (048d:8297)
- Intel Corp. (8087:0029)

Other PCI Devices: 	
- Phison Electronics E16 PCIe4 NVMe Controller | Non-Volatile memory controller (01:00.0)
- Phison Electronics E16 PCIe4 NVMe Controller | Non-Volatile memory controller (04:00.0)

I can see both NVME drives but the cache drive is not longer available for Unraid 😕

 

Do you know a workaround for this ?

Remote your vfio-pci.ids line, install VFIO-PCI config plugin (look in the app store), use that plugin (Settings -> VFIO-PCI CFG) to bind only the device that you need. That's the only way to do it when you have multiple of the same ID.

FYI, in 6.9.0-beta25, the plugin is built into Unraid and the binding can be done in Tools -> System Devices so the vfio-pci.ids method probably isn't required anymore.

Thank you very much for this plugin 👍

 

At first, I deactivated "PCIe ACS override" feature and remove the line from the "vfio-pci.ids=1987:5016".

But after I pass through the NVME 0, I had the following error at Unraid boot:

...
/etc/rc.d/rc.inet1: line 241: /proc/sys/net/ipv6/conf/eth0/disable_ipv6: No such file or directory
...
IPv4 address: not set
IPv6 address: not set
...

 

So I had no more network and even after rebooting in safe mode without plugins did not work.

I had to reboot in Gui mode to deactivate the passthrough of the drive and be back to normal.

 

So I figured out that I need to reactivate the "PCIe ACS override" feature.

By the way, do you know the difference between "Downstream" and "Multi-function" ?

As I did not know, I activated both.

 

Then I could start the Win10 VM with the NVME 0 passthrough as it has its own IOMMU group 🎉

My graphic card seems to work well as I did not need to install the drivers.

However, I had no internet inside the VM. I figured out that I needed to install the VirtIO drivers thanks to Default "Windows VirtIO driver ISO" feature.

 

But after installing, the VirtIO drivers, I have now a BLACK SCREEN after rebooting the VM 😩

I do not know why because the pass through of the graphic card was working well just before.

Please note that I installed the missing drivers only for the network card from the Device Manager panel of Windows by clicking on browsing on the ISO.

I have no graphic card on board.

VFIO-PCI binding will automatically try to bind everything in the same IOMMU group as the device you tick (because it would be pointless to bind part of an IOMMU group). Your NIC is in the same group as your NVMe so ACS override is the only way.

By the way, there's a VFIO-PCI.cfg file in the config folder of your flash - deleting that file will undo all the binding.

 

Graphic card without drivers is a myth. Always install Nvidia driver to verify your install, including rebooting your VM to verify reset issue.

 

You might want to watch SpaceInvader One tutorials on Youtube which probably will help with things.

Thank you for the precision regarding VFIO-PCI settings.

Even though, I did not get the difference between "Downstream" and "Multi-function".

 

Regarding the drivers, sorry for being unclear.

I installed all the necessary drivers including motherboard, graphic cards etc... during the install of the bare metal Windows.

That's why I just needed to deal with the network because as far as I understood it is the only part which is emulated.

When I successfully booted the VM for the first time, I had the same resolution than when booting on the bare metal.

 

I will have a look on the tutorial you mentioned, I already watched some but I guess I miss this one.

What bother me is that the display was working just before installing the VirtIO drivers...

Indeed, watching others tutorials from SpaceInvader One helped me.

 

I needed to dump the bios from my graphic card using the tool GPU-Z (HOWTO😞

As I have an Nvidia card, I needed to remove the header using the tool HxD (HOWTO😞

Then put the dump in a path like the following and update the VM template accordingly

  • /mnt/user/domains/hardware/GPU/Gigabyte.RTX2070Super.90.04.95.00.86.gpuz.noheader.rom

Finally, I needed to passthrough both GPU and sound of the graphic card using the multifunction method while editing the template with the xml view (HOWTO).

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x0b' slot='0x00' function='0x0'/>
      </source>
      <rom file='/mnt/user/domains/hardware/GPU/Gigabyte.RTX2070Super.90.04.95.00.86.gpuz.noheader.rom'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0' multifunction='on'/> <!-- Update here -->
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x0b' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x1'/> <!-- And here -->
    </hostdev>

 

I made a huge step as I could boot on my baremetal Windows VM.

However my graphic card seems to still not be recognized even after updating to the last Nvidia drivers.

 

Do the Gigabyte RTX 2070 Super is compatible with Unraid ?

I needed to boot Unraid in legacy mode while booting Windows Bare Metal in UEFI.

Therefore, I needed to change some settings in my Bios:

  • Enable CSM Support
    • Storage Boot Option Control: Legacy Only (ie: Boot Unraid in legacy mode)
    • Other PCI Device ROM Priority: UEFI Only (ie: Boot Windows Bare Metal in UEFI mode)

 

So the Windows seems to boot pretty well from Unraid.

However, I have an other issue in the Unraid Gui which seems to be down.

I do not know the exact reason. Maybe I allocated to many CPUs for the VM.

 

Luckily, I can still connect with ssh and perform a graceful shutdown.

I am almost there...
