August 1, 20169 yr Hi guys, Have a couple of VM's up and running, one which I've successfully added a GPU to (and old ATI card). I've now got another VM I'd like to add a GPU to. The card is an Nvidia GT 730 so it should work. When I assign the card and try and start the VM I'm getting the attached error. Any ideas? Thanks....
August 1, 20169 yr Please provide a diagnostics output so that we can better help you resolve the issue.
August 1, 20169 yr Author Thanks. I think this is the IOMMU group 1 issue so I may need to use ACS Override unless I can somehow figure out what other device is in that IOMMU group.
August 1, 20169 yr Author So if I'm looking at this correctly it looks like my Nvidia and ATI cards are clashing as they are in the same group. Hopefully it might just be a case of moving the ATI card to a different PCI slot. /sys/kernel/iommu_groups/1/devices/0000:00:01.0 /sys/kernel/iommu_groups/1/devices/0000:00:01.1 /sys/kernel/iommu_groups/1/devices/0000:01:00.0 /sys/kernel/iommu_groups/1/devices/0000:01:00.1 /sys/kernel/iommu_groups/1/devices/0000:02:00.0 /sys/kernel/iommu_groups/1/devices/0000:02:00.1 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller (rev 06) 00:01.1 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x8 Controller (rev 06) 01:00.0 VGA compatible controller: NVIDIA Corporation GK208 [GeForce GT 730] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GK208 HDMI/DP Audio Controller (rev a1) 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
