January 14, 20206 yr Hi everyone, I am about a day old to using unraid, and I have to say I have been delighted with how I have been able to get things started, although I am not especially technical. I have been able to create a Windows VM and I have been happy with it, but I want to start hardware passing through and I saw that I needed to enable IOMMU. So I went into the Bios and confirmed that SVM was enabled, but when I went back to info it is still indicating as below that IOMMU is disabled. This is my config and I was wondering if there was anything really obvious that would show that the hardware in incompatible with IOMMU. Model: Custom M/B: ASRock X570M Pro4 Version - s/n: BIOS: American Megatrends Inc. Version P1.50. Dated: 07/15/2019 CPU: AMD Ryzen 7 3700X 8-Core @ 3600 MHz HVM: Enabled IOMMU: Disabled Cache: 512 KiB, 4096 KiB, 32768 KiB Memory: 16 GiB DDR4 (max. installable capacity 128 GiB) ( Ballistix Sport LT Gray 16GB (2 x 8GB) DDR4-3200 UDIMM) Kernel: Linux 4.19.94-Unraid x86_64 Again I am not especially technical so I apologise in advance if I have asked anything stupid.
January 14, 20206 yr SVM just enables the virtualization features of the CPU itself. You're looking for an IOMMU option probably buried somewhere within Advanced in the BIOS
January 15, 20206 yr Author Solution Just a quick follow up. Found it in the end. Just in case anyone else wants to know and they own a ASRock Mobo Advanced --> AMD CBS --> NBIO --> there should be an Option for IOMMU.
