Unable to activate PCI devices

Hi team, I was trying to find a fix for enabling PCI devices when editing a guest and the input filter as well but so far I'm unable to test it with any VM that I try to run: "KCHVMHDEV0003E: No IOMMU groups found. Host PCI pass through needs IOMMU group to function correctly. Please enable Intel VT-d or AMD IOMMU in your BIOS, then verify the Kernel is compiled with IOMMU support. For Intel CPU, add 'intel_iommu=on' to GRUB_CMDLINE_LINUX parameter in /etc/default/grub file. For AMD CPU, add 'iommu=pt iommu=1'." Is this correct? Thanks, Samuel

Hi Samuel, Yeap, you need to enable enable IOMMU in the BIOS as described in the message below. Regards, Aline Manera On 03/11/2016 10:39 AM, Samuel Henrique De Oliveira Guimaraes wrote:

Is this correct?
