The reasoning is that a BIG patch thats very specific like this WONT make it into the kernel but by applying as a runtime patch it achieves the same end result (working VFIO passthrough for AMD GPUs). Would be killer if LT could make this easy to use in unRAID as the virtualisation is for some a key part of unRAID's appeal

You will probably need to provide more info than that to get help.. eg your VM XML Have U passed the GPU rom as well or not - I have no idea since you provided too little info... People cannot just diagnose on two lines of text!!

Is there any guide as to how to use this with unRAID? Is @jonp or @limetech going to integrate it?

Thanks... I did some searching and found this 4 port PCIe 3.0 card, cheap too, https://www.aliexpress.com/item/1005001590302280.html

How well did it work then?

Hi Looks like I have to move all my data back to a new unRAID server - so tell me, how long for parity build with 16TB drives and how long for parity check with 16TB drives? The price per TB seems to make 16TB drives sensible now.... I can live with long initial build but a weekly or monthly parity update could be an issue if it kills my Plex server!!

Pretty sure from memory when I looked at that board at launch it was 3rd slot wired to CHIPSET

Thread necro time but,... The way I read it, you need mobo sound activated and a pulse audio driver running and the your QEMU can pretend to have "sb16" sound in your Win98 VM and it would come out of the mobo sound ports. Would be sweet for some of the retro and quirky OS emulation.... I can think of 3 cases I would love to try

Another way to do it, without needing the unRAID UI is to run the script from the VM... so to switch from VM1 to VM2, just hit an icon to run a script from the VM you are closing

Using i440fx v4.2, Seabios, USB2.0 emulated, GPU passes through fine. Tried with passing through a USB3 controller (AMD platform only has USB3) but no dice Tried passing through a USB mouse as a device but not recognised. My Win7 VM boots to installer and sits there. Any ideas why?

Is there a clever way to script plug/unplug? With one GPU, I may want to close one VM and open another. I can do that by scripting it What would be good would be to script unplugging the USB devices from that VM before loading the next VM which would plug in the same devices. I would pass through USB controllers (and do) but not much use for Windows XP (no USB3) or Windows 2000 (no USB3) when my mobo only has USB3 controllers, no PCI slots for a USB2 controller and the only PCIe USB2 controller I found is stupid expensive for what it is. Scripting unplug after each VM close would be such a help. I assume its some sort of virsh detach command? @dlandon ??

Well I have Ryzen 3900x and get the same problem... Do you mean System Devices/AMD/ACPI... as there isnt one for me there....I have installed AMD chipset drivers as this "VM" was a baremetal install then converted to be able to dual boot bare metal or VM via unRAID

pass through a USB controller and problem solved...

Hi New install a couple of days ago and installed lots of plugins and 3 VMs. After a force restart I have the same errors on boot and cannot access webUI. You say you traced it to this plugin which I do have but what makes you think its that? I saw your post on the plugin thread but I see nothing to indicate why you are sure this is the cause? And is there a repair other than reinstall ALL MY UNRAID AGAIN!? Please no...

Another question (maybe an FAQ needed for this thread)? If I install Catalina and also want Mojave and High Sierra VMs, should I create 2nd and 3rd instances of Macinabox container? Or if I do not, will it just "know" to not wipe out my Catalina bits when I change the settings to Mojave?

@jonp this is VERY useful info (I have some OS to virtualise that only will work with these options) but please, do share where you got this info from? I am looking for the same on networking - I know we have vmxnet3 as an option but where is the list of what we could use??

I have no idea to be honest.. I have failed to find authoritative text that convinces me anyone really KNOWS which is best for VMs or when to use. I'm having issues myself with a simple Win10 VM (the one that was always easy a year ago when I used unRAID last) but my Ubuntu and Macos VMs are fine...

Have you tried i440fx rather than Q35 (as per SIO's video guide)??

Have you passed a USB controller? You can separate two identical ones using the latest SIO video. Passing the device is never going to be as good as passing a whole controller then you can hotplug ports.

Thanks. I left the RX5700 VM for ages.. I think it might need the "pikera mod" tweak in Clover? Not sure... But I swapped my RX570 in and I still got the confused looking load screen but it loaded.... Would love that setting that tidies up the screen immediately after Clover starts loading MacOS... Booting on my Navi isn't really important as I intend to leave 6 real cores on Windows/Navi (gaming & VR) and 4 real cores on MacOS/Linux/etc (for tinkering) with the other 2 real cores running unRAID (no Dockers as all my media etc is in a cloud box).

Hi, I came back to unRAID after a year away and loaded up Macinabox, installed Catalina, got it working fine via VNC. Adjusted number of CPU cores, Ram, etc. All good. Removed the install image (all good still). Added my Navi RX5700 to the VM plus the Rom file, fixed the network card, re-added the custom XML, deleted the topology (one time at least). Reboot and Clover hangs at a single Apple logo (offset to the left!) and 4 (more?) (small) copies of the "progress" bar loading. Ryzen 3900x BTW I wonder if this is related to it being 10.15.4 as on Hackintosh forums nobody is really using Clover for 10.15.2+ and moving to Opencore. Any ideas what the problem could be?

You could try posting your IOMMU groupings (not your VM XML yet) and your unRAID startup options (visible at the Flash sub screen). Maybe someone else will pipe up to help. I am done wasting my time trying to help and getting pissy posts.

Please dont blame me when you failed to ever provide the requested IOMMU groupings. I even PM'd you to explain how you failed to help yourself. Nothing I have suggested would have led to your VMs being deleted. I note you editted your brief previous message to add some detail but still you never provide the requested info. You wont help yourself but you want to blame me. Good show. Good luck getting anyone else to help with that attitude. Community here is good but being rude and deliberately difficulty is not the way to get help.

Please do make efforts to read the thread not just give up after 1st post is 5 years old You have (sorry) posted only an incomplete section of your groupings (I suspect you have more than 2 controllers!). The principles are laid out here clearly in thread. Make sure you have separate groupings, make sure your unRAID USB is NOT on a controller you decide to pass. Then stub ALL the items in that group (Sorry if this isn't a spoonfeed answer but I'm not running unRAID now, so not sure of latest method but it IS in the thread) and then reboot server and in the VM template you will have those stubbed items appear as passable PCI devices. Pass all the bits and then you should be golden.

Good idea.. then at least you WOULD be the right thread and wouldnt need to post again (PS edit would have sufficed rather than another post)
