Both say I am doing the right thing and that IOMMU should be working and I do not see my processor or mother board specifically on the supported hardware list. my machine is custom built: Processor (CPU) AMD Athlon 5350 Quad Core APU (2.05GHz/AM1) & Radeon™ HD8400 Motherboard ASUS® AM1M-A: (M-ATX, DDR3, USB 3.0, 6Gb/s)
Hi Robin, Qubes does a hardware test to determine if the IOMMU works. According to Wikipedia's "List of IOMMU-supporting hardware" page, https://en.wikipedia.org/wiki/List_of_IOMMU-supporting_hardware there are some ASUS motherboards that do not work correctly with IOMMU support. You may be unlucky.
There was a bug in earlier versions of Qubes that didn't report AMD IOMMU correctly. Thought it was fixed in 4.0.1, but try ignoring the warning and proceeding with the install. If it has trouble creating sys-net later on, the warning may be accurate. If you can get it installed enough to get to dom0, run qubes-hcl-report and note the last 5 yes/no lines.
