What is Microsoft Hyper-V Virtual Machine Bus (VMBus) Windows Driver?
The Microsoft Hyper-V Virtual Machine Bus (VMBus) driver is a component of the Hyper-V virtualization platform, which facilitates communication between the Hyper-V host (the physical server running Hyper-V) and the virtual machines (VMs) that are running on it. VMBus provides a high-speed data transport channel that allows the guest operating systems (inside virtual machines) to communicate efficiently with the Hyper-V host and other VMs.
The VMBus driver is installed automatically when you enable Hyper-V on the host machine. It enables efficient I/O operations (such as network, storage, and other system resources) between the virtual machines and the Hyper-V host, improving the overall performance of the virtualized environment. The VMBus driver also supports various integration services, like time synchronization, shutdown integration, and heartbeat between the VM and host.
