June 30, 20242 yr Hello all, I have moved from my old hardware (Z420) to a Lenovo P510. However I have found out that my plan to use a Windows VM as my machine has failed! After checking System devices I found that there's "No IOMMU Groups Available" In my P510 's Bios, there's an option to Enable Device Guard, but it will sacrifice the ability to boot from USB, which will reject the whole Unraid system to boot, as my photo below: Is there any workaround for this? The case has 4 SATA bays, and I did a small mod to turn its DVD bay into another 2 3.5 bays, while having my SSD hanging over, total of 7 drives and it consumes all SATA ports, so far I have only 10% of total storage space free so reducing a drive is not a choice for now. Even I have thought of a choice to buy a PCI to M2 card to add a M2 to boot, I don't know if Unraid support this booting device? If yes then how? (and so far I have just replaced my USB this year, dann!) Thank you and have a good day friends Edited June 30, 20242 yr by tungndtt more details
July 1, 20242 yr Not sure what device guard has to do with virtualization? Did you look for virtualization and vt-d options in the BIOS? Usually they are two separate settings, and for iommu you need both enabled.
July 1, 20242 yr Author As screenshot, you can see on the right panel, enabling this Device Guard will make VT-d, IOMMU enable but Ethernet/USB boot disabled. You can see this Warning when I chose to enable it:
