Yes, the number of VCPUs certainly matters to most tenants. But I doubt there
is much value in including this information into any measurment, as the
measurement does not guarantee the tenant that the host actually executes the
VCPU. The best proof for the existence of any given VCPU is the fact that it
executes code.
