I am trying to passthrough a graphics card to a KVM guest but have been unsuccessful.
The graphics cards has been attached and it does appear that the guest is aware of the card, I can see the kernel module has been loaded when I do lsmod.
Also I did notice that both the host and guest are loading the kernel modules for the graphics card. I have attempted to disable the host from loading the driver via the blacklist in /etc/modprobe.d but to no avail.
System specs are as below: - Centos 6.5 - i5-4460 CPU - H97M-D3H Motherboard - 2x Gigabyte 5450 PCI-E Graphics Card
I have enabled VT-x/VT-d and enabled iommu by adding "intel_iommu=on" the grub config file. Additionally, I have enable allow_unsafe_assigned_interrupts=1.
I understand there are later versions of the kernel that does a better job of passing through graphics card using vfio-pci. However, I would prefer using the upstream kernel that comes with CentOS at this stage.
If anyone can point me in the right direction, that'll be greatly appreciated. Thank you.
