old setup Ubuntu (scroll down to Fedora)
After hours of searching I decide to make a post.
I followed this video.
My problem is when I start qemu-system-x86_64 with my settings I get this error: Could not initialize SDL(No available video device) - exiting
My Setup:
new Ubuntu 17.10 setup
CPU: Ryzen 1700
Motherboard: Asus crosshair vi hero
GPU 1: Radeon HD 7950
GPU 2: Radeon HD 6850
gpus connected to one monitor
/etc/default/grub:
…
GRUB_CMDLINE_LINUX_DEFAULT=“amd_iommu=on vfio-pci.ids=1002:6739,1002:aa88 modprobe.blacklist=radeon”
…
vfio-pci.ids not working this why I use modprobe.blacklist=radeon but now I can only control the pc via SSH.
/etc/modules:
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
