I've been struggling with this for nearly 2 hours before I realized that
I was running a virtualbox vm in headless mode. Was trying to create a
qemu-kvm vm and it kept failing with symptoms similar to those reported
here.
What would be good is getting qemu-kvm to at least check if another
hypervisor is currently running, then allude that fact to the moronic
end-user and save the sucker from wasting 2 hours on a Saturday
afternoon chasing his tail!
This is the error I was getting:
