I am doing what you have there but on a much smaller budget than comfox
I picked up a Lenovo TS140 server, one of the E3 Xeon models, fitted 32GB ECC RAM to it. This model comes with a beefier power supply than the non-Xeon models so I could get away with a graphics card which requires the 6 pin extra line (again the lower TS140s don't have this extra cable in them) so I went with a Geforce GTX 950.
Got 3 x 3TB drives in for storage, a 512GB SSD for cache / VM duties. Whole thing runs really quietly as the E3 Xeons sip power when not under load.
Total price around £1000 I suppose but then there was a cashback deal on the server which gave me back 100 or so.
Runs VMs without any issue. I have a Win10 VM with GPU pass through for gaming. Currently getting OSX up and running. Also use various Windows Server VMs for development work and have 3 running at once (domain controller, SQL, other stuff) etc all without breaking into a sweat.
I also have dockers running for things like SAB, Plex, OpenVPN, nginx etc.

Thanks that helps quite a bit. I still have to use that plugin to re-attach if I swap but it doesn't happen often.
-
Is it possible to stop the VM complaining if there are some missing USB devices upon startup. I take my keyboard and plug it into a USB extension cable when I want to drive the VM with GPU passthrough physical and play games. But then when going back to do work on my Mac I switch the keyboard back again.
Now if I try to start that VM because I wish to RDP into it then it complains about the missing USB devices. I could go in and uncheck the boxes but that then removes my modified XML rom file entry for the graphics card.
Just feels like it could be a bit smoother and not worry if one of the USB devices is missing...
-
Okay I think I might finally have it working. After much hassle I managed to get another ROM dump from when the card was in slot 2, including by stopping/starting Vms. The second image was bigger than the first I took (134K vs 58K) and now setting that in the OVMF it works fine in the x16 slot.
-
Mmm same thing. Not getting a video signal from the card. Not sure I trust the ROM. have tried extracting again in slot 2 but now getting input/output error. Tried starting/stopping a bound VM as some others have suggested to then do an unbind but it stops being bound once the VM is shutdown and I still get input/output after that...
-
Okay many thanks for that. Tried it and the crashing has stopped!
However I am still not getting output on the card. Within Windows it shows up with an exclamation mark in device manager saying it has been stopped "Windows has stopped this device because it has reported problems. (Code 43)"
This was with my older seabios one though. Will try now with OVMF...
-
I am getting this as well but only when I pass through the GPU
-
So I tried setting the primary GPU in the bIOS to PCI and now unRAID recognises the card in slot 1.
However starting the VMs leads to unRAID hanging. I had originally set the primary graphics to IGP as I had read I needed to do that.
-
You are right, I was mistaken, it also says on the motherboard it is a 4x slot as well.
The BIOS was quite out of date and I have managed to update that now but no different, still not recognised in slot 1. Very frustrating.
-
Gone to previous seabios vm and slot 2 and all working fine...

Tried with a band new OVMF machine and now anytime I select the Nvidia card for passthrough the whole of unRAID hangs when I boot the VM ( I see the splash screen for Windows but then it hangs
-
I have a Geforce GTX 950 in a Lenovo TS140 running unRAID 6.2
It has a PCIEx16 (slot 1) and a PICEx8 (slot 2)
Now I know each should run just as fast but slot 1 would be better as it would lead to better air flow. The fans are very close to the bottom of the case in slot 2. However in slot 1 the card doesn't show up in unRAID. It is not listed in the list of System Devices. Move it to slot 2 it appears and I can select it for passthrough to a VM.
Any ideas why? My processor is a Xeon E3-1225 v3, it has on-board graphics and that s selected as the default graphics adapter in the BIOS I can confirm that when I boot the output is through on-board graphics and not the Geforce.

Okay it was pretty easy in the end. Set up a Windows VM, get it how I want it. Sysprep it with OOTB and shutdown. Then drop into SSH, make the image file read only, and run the following command:-
sudo qemu-img create -f qcow2 -b /var/lib/libvirt/images/myreadonlyimage.qcow2 /var/lib/libvirt/images/mynewvm.qcow2
then create a new VM XML pointing at the new file (I tend to use webvirtmgr in a docker for this)
-
Does anyone know how to create linked clones through the UI or through webvirtmgr (I have that installed in a Docker instance)
It should be possible to create a new VM which has a qcow2 disk based off a backing disk, i.e. the new disk only contains changes to the filesystem in the backing disk which remains "read only"
In VMWare world, this would be known as a linked clone and according to this chap is perfectly possible in KVM.

Just wondering if I need to jump into the terminal to achieve this, seems maybe I just do that to get the image file created and then create the VM and point to that image through the GUI?
-
Is there an easy way to change the mounted ISO in the virtual CD drive? all the examples seem to require command line but just wondering if there is an easier way?
I guess I can install VirtualClone drive or similar inside the VM (Windows) and use that to install software form the ISO but would be nice if there was a nice UI in unRAID to do it on the fly.

Download is working for me. I did however have an issue in creating the ISO image from the USB key. Not sure if this is a Sierra problem or not. In the end I have gone with a hybrid approach and created a blank file image using the instructions from danofun here:-

but then used the EFI folder provided by grid runner on his video example. Although I am obviously doing something wrong as I never get to the installer. get the Apple logo, then a loa of text, a reboot and then a no entry sign.
