I have an impression that terms "paravirtualization" and "full virtualization" are fuzzy nowadays. KVM, for example, reports steal time. Yet, KVM is considered to be full virtualization.

Many drivers, like virtio-blk, inevitably lead to conclusion that environment is virtualized, no matter what cpu says.
