I have a Dell R805 with 2 AMD Opteron 2356. I have been trying to configure and install Pfsense. The system has 4 NICs and I am trying to pass 2. When I try and start up the VM i was getting IOMMU error about passing PCI. I checked in the BIOS and virtualization is turned on. I have add the command for the AMD IOMMU. Now I get this
root@pve1:~# dmesg | grep -e DMAR -e IOMMU
[ 1.014654] PCI-DMA: using GART IOMMU.
[ 1.014657] PCI-DMA: Reserving 64MB of IOMMU area in the AGP aperture
root@pve1:~#
When I try and start the VM I am still getting Error: cannot prepare PCI pass-through, IOMMU no present.
