Short answer: No, you cannot run virtual ARM using KVM on physical x86.

Long answer: You typically need qemu emulator build specifically for the hardware of which you are trying to run the image from as a lot of the time the kernel isn't generic enough for a different board. Last I checked there was no specific qemu r-pi emulator, but there may be one now.

I hardly ever use VMs these days, I use a custom build kernel (for 4KB pages), and use containers instead if I only need to test/configure the userspace part.

I am trying to do so on a x86_64 Centos 7 host.  Is there not a way to
run Centos ARM on this architecture within a virtual machine?  I
skipped the relevant parts of the how to in order to get KVM working.
For example, I skipped installing AAVMF and used qemu-system-arm
instead.
