An engineering department is testing specialized hardware that must be accessible by one virtual machine. Which approach helps achieve near-native performance for the device?
Bridge the hardware through a software emulation layer for simpler management
Deploy high-availability clustering so the device is replicated across multiple nodes
Provision a dedicated device mapping so the guest operating system interacts with the hardware directly
Leverage a virtual bus driver in the hypervisor that presents a shared device to multiple guests
Direct device assignment, sometimes referred to by another name, grants close-to-bare-metal access to a single guest operating system, minimizing hypervisor overhead. Other approaches either employ extra abstraction layers, share the device more broadly, or distribute workloads across nodes. These methods do not provide a dedicated path for the specialized hardware and add latency that reduces performance benefits from the unique device features.
