Fair question :) System information from 'Info' link in UNRAID: M/B: Supermicro - X8DT6 HVM: Enabled IOMMU: Enabled Cache: 256 kB, 1024 kB, 12288 kB Memory: 24 GB Multi-bit ECC (max. installable capacity 384 GB) Kernel: Linux 4.14.40-unRAID x86_64 OpenSSL: 1.0.2o Video Card info from System Devices: IOMMU group 14: [8086:244e] 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 90) [102b:0532] 01:03.0 VGA compatible controller: Matrox Electronics Systems Ltd.

Is there any other data that may be of use?

Hello! I'm running a trial of unraid 6.5.2, and am having some difficulty getting VMs to run when they're configured to leverage a dedicated GPU/Graphics Card (vs. VNC). While the VM runs fine via VNC, when using a GPU, it fails to start. The VM log has the following error/warning: qemu: hardware error: vfio: DMA mapping failed, unable to continue I've tried disabling SR-IOV, as well as enabling PCIe ACS Override with no luck. Any suggestions on what else to try? Is there any additional data that I should include here? Thanks in advance!
