Thanks Christian.
Sadly, I don't care to create and spin up KVM instances from a command
line, I prefer (as I presume most people do) to use virt-manager.
When I set dynamic_ownership = 0, I am unable to boot due to a
permission denied error:

So if I change it back to 1 and restart libvirtd I can start KVM instances, but
we're back to the original issue.
Is there some other setting necessary so virt-manager (running via my
normal user) doesn't try launching things as the libvirt-kvm user, which
is what I presume is the root of all this?

Or... also possible, am I just confused?
