Hello, I have GVT-D working in legacy mode on Windows 10 with i440fx machine type and the i915ovmf rom. (Intel UHD P630) I’m now trying to get it to work also with a MacOS Sequoia VM. There I’m forced to use q35 machine type otherwise I struggle to boot, which means that I would have to use UPT mode instead of legacy mode. A user in a discord channel of the i915ovmf rom has reported success with GVT-D and MacOS by patching the qemu source to remove the check of the device present at address 1f to allow legacy mode on q35. I was wondering if this would be possible to achieve also in Unraid? Searching the forum I found a post from @ich777 that mentioned a custom Qemu build. Thank you in advance.

Hi @jbartlett, is ZFS support now implemented or not yet?

Thanks for the reply. Is there any plan to support multiple partitions in the GUI?

Hi all, I have a raidz2 ZFS pool with 8 main drives and an optane drive that is split in 2 partitions, one assigned as SLOG device and the other as L2ARC. The pool was created under Unraid 6.11 using the ZFS plugin. Since upgrading to 6.12 (and the removal of the ZFS plugin), I've been manually mounting the ZFS pool at array start with a user script. Everything was working perfectly. I'm currently on 6.12.15 and I've decided to import the pool in Unraid to benefit from the extra UI integration. However, with the pool imported in Unraid and having disabled the script that manually mounts the pool, none of the datasets in the pool get mounted and the status in the bottom left on the Unraid page is stuck at Array starting - Mounting disks... If instead I manually mount the pool, it works correctly. I've attached the diagnostics before manually mounting the pool Also, you can find below the output of zfs list root@Jarvis:~# zfs list NAME USED AVAIL REFER MOUNTPOINT disk1 641G 282G 128K /mnt/disk1 disk1/appdata 9.53G 282G 9.53G /mnt/disk1/appdata disk1/data 11.1G 282G 11.1G /mnt/disk1/data disk1/docker 8.37G 282G 8.37G /mnt/disk1/docker disk1/dockers 96K 282G 96K /mnt/disk1/dockers disk1/domains 589G 282G 589G /mnt/disk1/domains disk1/isos 22.7G 282G 22.7G /mnt/disk1/isos disk1/libvirt 110M 282G 110M /mnt/disk1/libvirt disk1/system 38.2M 282G 38.2M /mnt/disk1/system zfs 8.70T 11.9T 273K /mnt/zfs zfs/Backup 1.28T 11.9T 1.28T /mnt/zfs/Backup zfs/Dati 1.85T 11.9T 1.22T /mnt/zfs/Dati zfs/Download 18.6G 11.9T 18.6G /mnt/zfs/Download zfs/Film 4.11T 11.9T 4.11T /mnt/zfs/Film zfs/Foto 687G 11.9T 673G /mnt/zfs/Foto zfs/Musica 5.00G 11.9T 4.99G /mnt/zfs/Musica zfs/TimeMachine 677G 11.9T 520G /mnt/zfs/TimeMachine zfs/test 110G 11.9T 110G /mnt/zfs/test zfs/test2 39.0M 11.9T 39.0M /mnt/zfs/test2 zfs/test4 5.55G 11.9T 5.55G /mnt/zfs/test4 zfs/test5 39.0M 11.9T 39.0M /mnt/zfs/test5 disk1 is the main Unraid array which is also formatted as ZFS and doesn't have any issue with mounting the datasets. The problematic pool is zfs Below you can find the output of zfs mount root@Jarvis:~# zfs mount disk1 /mnt/disk1 zfs /mnt/zfs I found this bug report that was describing the same issue that I'm encountering but in that case the culprit was the sharenfs feature being enabled which in my case is off for all datasets. Any suggestion on how to get the datasets to mount correctly? jarvis-diagnostics-20250128-2147.zip

Hi @BVD, thank you very much for the very detailed guide. Do you know if this could work also for PCI-E GPUs with SR-IOV support?

Thanks @JorgeB I just upgraded to 6.12 and everything appears to be working as expected. I’m running the zpool import command from a user script that is set to run at first array start only. It works but I need to force a refresh of the ZFS master portion of the dashboard the first time I open the page. Almost as if the pool is mounted after the ZFS master plug-in scans for available ZFS pools. I will try to move the command to the go script to see if it makes a difference.

Thanks @JorgeB At the moment I'm not mounting it manually, it is done automatically by the ZFS plugin. Do you happen to know what would the command be to properly mount the zfs pool?

Hi, I’m currently still on Unraid 6.11. I have 1 standard array made of a single nvme drive that I use for dockers and VMs, and that is mounted as default. While the main data “array” is a 8x HDD ZFS pool that I created using the plug-in and that uses a custom mount point at /zfs. I have a lot of user scripts that access the datasets/pool using that custom mount point and I would like to keep those unchanged. If I upgrade to Unraid 6.12, is there a way: 1) Have 2 arrays. One for the fast NVME drive (either xfs or zfs) and one for the large (but slow) ZFS pool? 2) Keep the custom mount point for the zfs pool? Thanks Andrea

Quick update on some findings. 1) I took the source code of eglinfo, which is a tool that is part of the mesa-tools and that lists the EGL capabilities of the system (the equivalent of glxinfo or EGL). 2) I modified the source code to implement the creation of the GBM surface in order to query the capabilities of off-screen rendering of the system, instead of on-screen. This is basically the equivalent of what QEMU does, in fact I copied the relevant portion from the QEMU source code.

support to EGL_MESA_platform_gbm which is required for off-screen rendering. 6) Instead, running the same code on Unraid produces the following output: EGL client extensions string: egl: eglGetDisplay failed: EGL_SUCCESS As you can see, the GPU driver on Unraid doesn't support any EGL extension, making off-screen rendering impossible! I've raised a bug on the bug reporting section of the forum, because QEMU is compiled with OpenGL support but the GPU drivers that are shipped with Unraid are the limiting factor to make QEMU work correctly with OpenGL:

Thanks. In the meantime I will keep investigating because I would like to find a solution without having to wait for the next Unraid release

I have a supported CPU (i3-9100) and I already use the GVT-g plug-in. With that, GVT-g works perfectly in a Windows 10 VM. The way it works in the Windows 10 VM is that the primary gpu (the one used with VNC access) is an emulated device, while the mediated device is a secondary GPU that is used via RDP to provide hardware rendering. I’m trying to get GVT-g working also with MacOS, and for that the mediated device needs to be the only video device presented to the guest. For that reason I have to enable display=on in the hostdev entry in the xml and use egl-headless combined with VNC or Spice (as per instructions from my first post). I don’t even think that the qemu command goes as far as trying to boot the OS, it fails already when trying to setup the display output. From qemu 8.0 the log will show what is the actual error for failing to get the display, as you can see here: https://github.com/qemu/qemu/blob/83a9cdbd65ceb4a443630aed011a00ef217ed408/ui/egl-helpers.c#L485 The error can be one of the following: switch (error) { case EGL_SUCCESS: return "EGL_SUCCESS"; case EGL_NOT_INITIALIZED: return "EGL_NOT_INITIALIZED"; case EGL_BAD_ACCESS: return "EGL_BAD_ACCESS"; case EGL_BAD_ALLOC: return "EGL_BAD_ALLOC"; case EGL_BAD_ATTRIBUTE: return "EGL_BAD_ATTRIBUTE"; case EGL_BAD_CONTEXT: return "EGL_BAD_CONTEXT"; case EGL_BAD_CONFIG: return "EGL_BAD_CONFIG"; case EGL_BAD_CURRENT_SURFACE: return "EGL_BAD_CURRENT_SURFACE"; case EGL_BAD_DISPLAY: return "EGL_BAD_DISPLAY"; case EGL_BAD_SURFACE: return "EGL_BAD_SURFACE"; case EGL_BAD_MATCH: return "EGL_BAD_MATCH"; case EGL_BAD_PARAMETER: return "EGL_BAD_PARAMETER"; case EGL_BAD_NATIVE_PIXMAP: return "EGL_BAD_NATIVE_PIXMAP"; case EGL_BAD_NATIVE_WINDOW: return "EGL_BAD_NATIVE_WINDOW"; case EGL_CONTEXT_LOST: return "EGL_CONTEXT_LOST"; default: return "Unknown EGL error"; For older versions of qemu, the log message doesn’t display what the error actually is (see the GitHub link from the first post). As far as I can see, there is no way to get qemu 8.0 on Unraid at the moment, is that correct?

Hi all, I'm trying to create a VM that uses "egl-headless" graphical framebuffer, combined with VNC or Spice to enable hardware acceleration on the guest with a mediated device (iGPU). I've followed this guide: https://wiki.archlinux.org/title/Intel_GVT-g As far as I know, starting from Unraid 6.10, QEMU has been compiled with OpenGL support, therefore this should be possible.

Hi all, I came across this reddit post: https://www.reddit.com/r/VFIO/comments/innriq/successful_macos_catalina_with_intel_gvtg/ that reports partial success (no hardware acceleration) of GVT-g on a MacOS VM using a custom VBIOS. The instructions to set it up on Fedora and Linux are available on this GitHub page: https://github.com/patmagauran/i915ovmfPkg/wiki/Using I'm trying to make this work on Unraid. I already have the Intel GVT-g plugin from @ich777 installed and it works correctly on a Windows 10 VM. I've used the Macinabox docker container to install MacOS Monterey: Without assigning any vGPU to the MacOS VM it works just fine with software rendering. I then created compiled the custom ROM, created a new vGPU instance, assigned it to the MacOS VM, and I have modified the xml to closely match the instruction shown for QEMU on the GitHub page. This is what I have in the end: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>MacOS Monterey</name>

I can still access the Unraud console if I open it beforehand but even trying to stop libvirt doesn't work..the command hangs. I have no way to access the VM log to see if there are any errors. The freeze happens even if I don't specify the custom ROM. Do you know what's going on? Would you be able to help me? Thanks Andrea
