Paravirtualization

In hardware-assisted full virtualization, guest operating systems issue calls directly to the hardware. In paravirtualization, guest operating systems communicate with the hypervisor (KVM/QEMU) with an API (Virtio). This API defines paravirtual devices including Ethernet cards, disk I/O subsytems, and VGA interfaces with SPICE drivers.

For an overview of VirtIO, see: https://www.cs.cmu.edu/~412/lectures/Virtio_2015-10-14.pdf
