January 3, 20179 yr Hello everyone, I've got a problem with my Unraid system. It says that IOMMU is disabled but the CPU supports VT-D and it is enabled in the bios. Does anyone know why this is?
January 3, 20179 yr Hello everyone, I've got a problem with my Unraid system. It says that IOMMU is disabled but the CPU supports VT-D and it is enabled in the bios. Does anyone know why this is? WAG, old BIOS?
January 3, 20179 yr Are you sure the BIOS setting for virtualization is turning on VT-d rather than just VT-x? I know my P5B doesn't support VT-d, and support for it was very rare (if ever) during the LGA775 era.
January 3, 20179 yr Author thanks for your quick reply. this old computer is my unraid test machine. To see how it all works before I reinstall my XPenology nas into an unraid version. but here is a screenshot of my bios. Vanderpool Technology should be the same as vt-d.
January 3, 20179 yr I'm pretty sure that Vanderpool was the old name for Intel® Virtualization Technology, but that's VT-x. You need Intel® Virtualization Technology for Directed I/O to get VT-d support.
January 3, 20179 yr The Q9450 supports VT-d, but the motherboard is the question/issue. Unfortunately the 2500k doesn't support VT-d.
