So it's been a little while and I've been trying some different approaches. I think the problem I am having is because I don't have the required kernel modules loaded. When I run lsmod I only see the following two modules loaded:
Module Size Used by nfsd 100940 11 exportfs 6723 1 nfsd The archlinux website says the following modules need to be running: kvm_intel 245760 0 kvmgt 28672 0 mdev 20480 2 kvmgt,vfio_mdev vfio 32768 3 kvmgt,vfio_mdev,vfio_iommu_type1 kvm 737280 2 kvmgt,kvm_intel irqbypass 16384 1 kvm Granted that I am running on a powerpc processor not an intel processor, the modules that I myself to need to load will be a little different from that. But I can't find those modules to load on my device. For example, I can't find a kvm.ko file on the device despite the fact that I was able to find the kvm directories I mentioned earlier. Did I have to compile those modules myself? In the kvm module directory there is C code and a makefile, but just running make doesn't work. Note that I'm using a Yocto Linux system that I myself didn't build. My coworker built the Linux system on SD card and was in the process of trying to figure out if kvm was actually enabled on the system or not before he left the company. I'm learning about the system as I go.
