neba Posted May 21, 2023 Share Posted May 21, 2023 I have unraid 6.11.5 installed on Maximus III Formula (Intel P55 chipset), CPU Intel® Core™ i7 870 and NVIDIA GeForce GTX 960. Under System Information - IOMMU:Disabled. When i want to install VM under Graphics Card: I have only Virtual. Is the problem only with the m/b (bios), not sure if the m/b supports IOMMU or something else. Quote Link to comment

Squid Posted May 21, 2023 Share Posted May 21, 2023 54 minutes ago, neba said: not sure if the m/b supports IOMMU or something else You need to enable both Virtualization support (VT-x) and IOMMU / Vandendool / VT-d in the BIOS. VT-x is usually easy to find. VT-d is likely buried within various sub-menus in the BIOS Quote Link to comment

Solution Jumbo_Erdnuesse Posted May 22, 2023 Solution Share Posted May 22, 2023 (edited) Your system does not support IOMMU. It was in the cpus from AMD since the Athlon Processor ermerged. Intel only had that feature in their Xeon processors. For consumers IOMMU was available from Intel since 2011. The Core I7 2600 has IOMMU the Core I7 2600K did not support it. Not all mainboards had options in their BIOS to turn that on. Since the Core 4000 series it became part of all Intel platform chipsets and cpus.

neba Posted May 22, 2023 Author Share Posted May 22, 2023 (edited) What do you think of 9th generation Intel Core Processor (i7 9700K or i5 9400) and m/b with z390 chipset? Edited May 22, 2023 by neba Quote Link to comment

According to Intel Ark the i7-9700K CPU supports VT-x and VT-d and the Z390 chipset supports VT-d. Quote Link to comment
