I have installed the ubuntu supplied version.

But KVM/Qemu is not being invoked. After a fresh boot on bare metal, these are
the results I get in a root TTY. 

I have seen mention of vfio-pci using device specific resets though.

So I will try to completely take it out of my test.

I'm not sure about pci config access, since I don't know how to verify this.
Any instructions would be appreciated.
