That's the correct way.

This looks like a bug - a guest cannot exist without at least one vcpu.

That only says your host has 2 cpus that the guest can utilize; it says
nothing about what type of cpu the guest will see.
You're mis-interpreting the data here. 'vpucinfo' info repeats these
four lines of data per VCPU.
So this is saying that the first vCPU, #0, is running running on host
CPU #2.
The total number of guest CPUs is shown by 'virsh dominfo'
The total number of host CPUs is shown by 'virsh nodeinfo'
