Ubergeeksov Posted April 2 Share Posted April 2 Hi, I have Unraid (6.12.9) running on my 2014 iMac (which was "retired" by Apple a couple of years ago). I have followed Ailetics walkthrough ( Everything seemed to be going fine (up and running through VNC) until I tried to passthrough the GPU. In the VM edit I changed the graphics card from virtual to my iMac's Radeon R7 370 / R9 270X/370X and changed the sound card to the iMac's AMD HDMI Audio (Radeon HD7000 Series). When I start the VM the screen on the iMac goes blank (having been showing the Unraid boot up sequence), but no appearance of Windows 10 on screen. I've not added a Graphics ROM Bios. Any suggestions? Quote Link to comment
bmartino1 Posted April 2 Share Posted April 2 post your vm xml review did you make the necessary edits for the xml to use the GPU/Audio correctly? Is IOMMU enabled? Dashbaord INFO did you stub the Gcard? the gcard need to be bound. Quote Link to comment
Ubergeeksov Posted April 3 Author Share Posted April 3 Hi, vm xml below. Yes - made the necessary edits to xml - which I think are correct. Yes - IOMMU enabled (I assume this is the action taken in Tools > System Devices) I don't understand what you mean by Dashboard INFO. I do not understand what you mean by "stub the Gcard".

bmartino1 Posted April 3 Share Posted April 3 I'm reviewing your XML for fixes. atm see above for simalr help with another user. Quote Link to comment
bmartino1 Posted April 3 Share Posted April 3 (edited) In your XML you have the VNC feature set: <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> ^ this must be deleted via the web GUI then edit the XML. Edits in the GUI will delete any and all custom XML. But yes, this is perfect and correct to fix g-card XML bind: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0' multifunction='on'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x1'/> </hostdev> From the data here, your g card is in pcie host slot 1 and will use virtual machine slot 6 for the g card. Multifunction is there and audio is set to same slot and using correct function. Be sure to pass all g card devices. Some may need to pass a USB (i'm looking at use 2080 super!) since your web gui option didn't have the g card first, the default monitor is using VNC. VNC needs to be disabled and the g-card set as default for visual out. You should see the g card under the vm tab: Edited April 3 by bmartino1 Quote Link to comment

bmartino1 Posted April 4 Share Posted April 4 you appear to be having a vfio error: per vfio log: "2024-04-04T08:35:33.478154Z qemu-system-x86_64: vfio-pci: Cannot read device rom at 0000:01:00.0" this is preventing the device use in the vm open terminal on the unraid machine and scroll to the top to find device 1:00 the g card the command lspci -v what does the driver in use say? ############################## Lets review some potential fixes. first we may need to eanble pci overrides to allow upstream and downstream comunication. settings > VM (advance toggle Set PCIe ACS override to both. this will add a grub setting to Unraid Fix 1: grub edit to prevent a FB on the g-card (if the system uses the g-card before the vm touches it, it loads memory to the card . This can break vfio): a reboot will be required after seting this setting. IOMMU groups may change as well. Next we will add some other grub items (optional but recommend) /Main/Settings/Flash?name=flash we will be editing the green box here is my example: (green is the default selected for boot.) Sometimes vm setting adds the grub syntax in the wrong area. and the entire thing needs to be re written. here is the corect syntax and settings that we want grub to load: kernel /bzimage append initrd=/bzroot pci=noaer pcie_aspm=off video=vesafb:off,efifb:off,simplefb:off,astdrmfb initcall_blacklist=sysfb_init pcie_acs_override=downstream,multifunction not all permeates will work with unraid. Some are basked in. normally to enable iommu we would add iommu commands to this... https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt Why these grub otpions: pci noaer is to fix log spam of pci devices. pcie_aspm off is to turn off pcei control over ther power managment the vm will be doing this now. the long video= string is to stop teh FB on all g-cards. there was a lts update that bork optin video=simplefb:off the fix was the initcall option... 80% of the time its either a power management thing breaking or something touched and used the card before the VM. ^this should fix the vfio error in the log. A lot of this came from in house testing with multiple devices and other os fixes. the goal is to get the kernel drive in use to vfio-pci on the device meant for vm only. There is a os unraid release, I recommend updating to 6.12.10 to fix access to system drivers. the other option is to ease the card at boot into vfio Tools/SysDrivers at the top to find vfio you need to go to all we will click the edit option here: 4 and add this softdep radeon pre: vfio-pci softdep amdgpu pre: vfio-pci #AMD GPU options vfio-pci ids=1002:6810,1002:aab0 disable_idle_d3=1 disable_vga=1 don't forget to save at the right of the box. rebuild at bottom and then reboot system. vfio log should be successful and terminal lspci -v should show the g-card in vfio-pci for driver in use. we will need the output of the lspci -v command to assist further. We will also need to ( I need to find the dmesge command to verify iommu again...) HVM and IOMMU needs to be on HVM is the hyperviosr check for system controls. Iommu is memory remapping that is needed to use vfio. Quote Link to comment
bmartino1 Posted April 4 Share Posted April 4 Verifying IOMMU parameters dmesg | grep -e DMAR -e IOMMU Intel will show something similar: There should be a line that looks like "DMAR: IOMMU enabled". If there is no output, something is wrong. Verify IOMMU interrupt remapping is enabled It is not possible to use PCI passthrough without interrupt remapping. Device assignment will fail with 'Failed to assign device "[device name]": Operation not permitted' or 'Interrupt Remapping hardware not found, passing devices to unprivileged domains is insecure.'. All systems using an Intel processor and chipset that have support for Intel Virtualization Technology for Directed I/O (VT-d), but do not have support for interrupt remapping will see such an error. Interrupt remapping support is provided in newer processors and chipsets (both AMD and Intel). To identify if your system has support for interrupt remapping: dmesg | grep 'remapping' If you see one of the following lines: AMD-Vi: Interrupt remapping enabled DMAR-IR: Enabled IRQ remapping in x2apic mode ('x2apic' can be different on old CPUs, but should still work) then remapping is supported. If your system doesn't support interrupt remapping, you can allow unsafe interrupts ^enabled under unraid VM settings... Quote Link to comment
bmartino1 Posted April 7 Share Posted April 7 https://apple.stackexchange.com/questions/394967/how-do-i-enable-intel-virtualization-in-a-macbook-pro ⌘/⌥/ O/F is the old PPC Open Firmware command. It doesn't work on Intel Supported but Disabled/Locked Apple provides a support document, If VT-x virtualization technology is locked or disabled on your Mac to address this issue. Basically, you need to ensure your software is updated to latest version. VT-x is enabled by default, but there's no "setting" or command that can be issued to turn it on. Try resetting the NVRAM by holding ⌘ Command⌥ OptionPR while booting. You can issue the command nvram -xp to dump the NVRAM contents. If you parse through it, you won't find any variable related to virtualization. https://support.apple.com/en-us/101294 I think the 2014 imac has vt-d locked which is preventing pcie passthrouh. You can try to get ti to work by enableing vm setting advance: VFIO allow unsafe intrupts. Quote Link to comment
