SR-IOV Technology Architecture: Hypervisor, Adapter, and Virtual Machines #305451 (License: Personal Use)

This diagram depicts the layered architecture of Single Root I/O Virtualization (SR-IOV), where an SR-IOV-capable PCIe adapter sits between the physical device (e.g., server) and the hypervisor, allowing virtual machines to bypass the hypervisor for direct hardware access. The three virtual machines each receive dedicated virtual functions (VFs) from the physical function (PF) on the adapter, reducing CPU overhead and improving network/storage performance. The dashed boxes represent logical partitioning of resources under the hypervisor’s control.

Used in enterprise virtualization documentation, cloud infrastructure guides, or technical whitepapers explaining hardware-assisted virtualization; targets IT architects, DevOps engineers, and system administrators seeking performance optimization in VM environments.
