slizz Posted November 27, 2016 Share Posted November 27, 2016 I have a Windows 10 install that is working well. I can RDP into it when assigning the VM to VNC. Once I assign my GPU (AMD RADEON 7970) it doesn't show up on a connected monitor and I can no longer RDP into the VM. It may not even be booting. I had a Windows 10 VM working fine with this GPU and pass through yesterday. I just decided to get rid of that VM and do a clean install because of some errors that I made. HVM and IOMMU are enabled. PCIe ACS override is on. The previous working VM I had was set up originally in unRaid 6.1. I am currently using version 6.2.4. Thanks for any insight. Quote Link to comment

1812 Posted November 28, 2016 Share Posted November 28, 2016 not an expert here: but since you have 2 devices in IOMMU group 12 (03:00.0 and 04:00.0) you might make sure you're also passing through the bridge (03:00.0) as well as the gpu (04:00.0) , since KVM wants the entire group.... or so i'm told.

slizz Posted November 28, 2016 Author Share Posted November 28, 2016 What do you mean pass through the bridge? I have br0 selected in the VMSettings as the default network bridge. Quote Link to comment

1812 Posted November 29, 2016 Share Posted November 29, 2016 What do you mean pass through the bridge? I have br0 selected in the VMSettings as the default network bridge. WAIT is that the onboard graphics (04:00.0)? if so IGNORE what i put before. It was late and I glanced at your post... instead when you assign this gpu: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti XT [Radeon HD 7970/8970 OEM / R9 280X] [1002:6798] then you need to assign through this audio at the same time: 01:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti HDMI Audio [Radeon HD 7870 XT / 7950/7970] [1002:aaa0] since both of those are in the same IOMMU group. unless you're doing that already? please post your xml. Quote Link to comment
thaddeussmith Posted November 29, 2016 Share Posted November 29, 2016 Check my recent thread for some ideas as well.. Lots of head banging before an obscure setting was suggested. http://lime-technology.com/forum/index.php?topic=54059.0 Quote Link to comment
SpaceInvaderOne Posted November 29, 2016 Share Posted November 29, 2016 I have a Windows 10 install that is working well. I can RDP into it when assigning the VM to VNC. Once I assign my GPU (AMD RADEON 7970) it doesn't show up on a connected monitor and I can no longer RDP into the VM. It may not even be booting.

PCIe ACS override is on. The previous working VM I had was set up originally in unRaid 6.1. I am currently using version 6.2.4. Thanks for any insight. Please try setting up a new windows 10 VM. But choose seabios for the bios type. ( In 6.19 the unRAID version in which you set up the vm which worked, by default windows VMS defaulted to seabios. From version 6.2 they default to ovmf.) I suspect that your GPU doesn't have an EFI bios ,which it would need to work with an ovmf VM hence the black screen. Quote Link to comment
slizz Posted December 2, 2016 Author Share Posted December 2, 2016 Well folks...turns out I'm just not very smart. I had assigned a static IP when accessing in VNC. When I changed to the GPU it changed the static connection back to DHCP which is why RDP was not working. I realized this after a restart of the VM while sitting at my TV which is connected to the GPU rather than doing it from the other room....Doh! Thanks for all of the help as always.
