QEMU offers fast virtualization by emulating hardware memory maps with specific side effects, allowing for efficient guest OS operation. This even includes virtio-net drivers enhancing network traffic without raw bare-metal support. Originally part of QEMU's development, it has since evolved into an integral feature.

QEMU Virtualization: Emulating hardware memory maps for efficient guest operation.
Virtio-Net Integration: Virtio-net drivers enable optimized network traffic with side effects, despite lack of direct hardware support.
Evolutionary Development: QEMU's virtio implementation grew from initial design to a key virtualization feature.
Guest OS Interaction: The guest system interacts with the simulated memory, mimicking effects as if run on real hardware.
