October 13, 20169 yr Hello! I'm only day 6 or so of my trial version, and have already upgraded to a VT-d system so that I can run VMs. I'm basically following the advice from Linus' Tech Tips Gaming NAS video. The plugins and dockers, while a real finicky pain in the arse to setup, seem to work well enough. However, VMs are not working at all. Win10: Assigned keyboard and mouse flash when the VM starts, monitor has no signal. Win7: Same as Win10, but I can install the operating system and run it for a while. (2nd time I tried this, the keyboard didn't respond for some reason). However, when I shutdown the VM via the Win7 shutdown button, it freezes on the shutdown screen and will only reboot into system recovery. Even if I load the drivers to point Sys Rec to the Win7 VM and run repair, it will still only reboot into Sys Rec. VM settings http://i.imgur.com/fhXEg7v.png Here's my config:

October 14, 20169 yr Author One discrete card = ATI HD7850. I had to enable PCIe ACS to get Win7 to show up at all.
October 14, 20169 yr You're going to have much more success overall with Windows 10 vs Windows 7 especially when passing through devices. Since you say that Windows 7 gives you a screen output, I tend to think that your 7850 supports UEFI boot (some cards do not). I'd recommend sticking with Windows 10 create a new Windows VM template, and toggle the advanced view button in the top right corner. You can then set the BIOS to SeaBIOS instead of OVMF/UEFI. You can also set the machine type under advanced view, recommend leaving that at the default which should be i440FX-2.7 If you wanted to stick with OVMF, you can also supply the rom to the GPU in order to possibly alleviate the black screen, however what I suggested above is just easier to do. Update with your success or failure, if failure I'd try the rom option which has details in both the Wiki and also in posts here in the forum.
October 16, 20169 yr Author Thank you for the help! Notably, I am only provided i440fx-2.5, not 2.7. By default, I was using the Win10 template, adding 3 cores, 8GB RAM (min=max), GPU passthrough, USB keyboard and mouse passthrough, and (inconsistantly) on-board audio card passthrough. From there, I followed each step in the wiki for getting past the black screen. After each failure, I removed the VM+Disks. I finally received video output and could safely restart the OS after changing the machine type to Q35-2.5 (latest) and BIOS to seaBIOS. I'll use this (VM1) for a bit and report back if that was all that was required. EDIT-Failed again. After successfully installing Win10 and device drivers, I started Ninite in the background for basic programs and RTEs. Win10 UAC was set to the next to lowest setting. Near the end of the install, the screen flickered to black and then blacked out completely. The only way to stop the VM was a Force Stop. It rebooted back into Win10 just fine and sat idle at the login screen for a few minutes. I logged in and started surfing the net when the screen went black in exactly the same fashion. The behavior is repeatable. Guess I'll go back to adjusting VM settings. I'm leaving this (VM2) for future debugging if necessary. EDIT2 - A new hope. It seems the only setting I need to get the display to work with Win10 is the BIOS set to seaBIOS. Strangely, each time I've installed Win10 I've had to go through the "Get going fast" screen, where you can customize privacy settings, twice before setting up the user account. So, here we have VM3. I installed device drivers and started in on individual program installers instead of Ninite. At some point, the screen flashed to black but within a few seconds came back up in a higher resolution! I wonder if this is what was going on before, but something prevented it from coming back after the automated change of resolution?
October 16, 20169 yr Sounds like this is progressing somewhat, so that's good to hear. I'd recommend trying the 6.3RC as you may have better luck with newer kernel/qemu. This would also give you the 2.7 i440fx, however I doubt that within itself will resolve much in regards to your situation.
October 17, 20169 yr I've been battling with VMs too. I got a number of suggestions, but the one that made a difference was limiting the VM to a single thread on my CPU. For you, just 1 core. I'm curious if that works for you, because I might start a new thread for that issue. Here's the discussion I had for my system. There might be a few good ideas for you there: https://lime-technology.com/forum/index.php?topic=52613.0
October 30, 20169 yr Author Per: https://www.tapatalk.com/topic/18593-unraid/50842-gpu-ovmf-compatibility-check ...my GPU doesn't support UEFI/OVMF bios. My latest attempts at creating Win10 VM4-VM6, with seaBIOS and varying the machine type and run time installations, ended with a blue screen and "VIDEO_TDR_FAILURE" report. That's the end of the journey for me. I'm going back to running Windows as the primary operating system and will run any systems within it. Thanks for the help, everyone. Sorry there's no happy ending this time.
