What is the difference between a virtual machine and a virtual switch in Hyper-V?
A virtual machine (VM) in Hyper-V refers to a software-based emulation of a physical computer, allowing users to run an operating system and applications in an isolated environment on a host system. Each VM has its own operating system, network interfaces, and associated storage. This segregation enables users to test software, run different operating systems, or host applications without affecting the host server’s primary operations.
In contrast, a virtual switch is a component of Hyper-V that facilitates communication between VMs and the external network or between VMs themselves. Just as physical switches connect multiple devices in a network, virtual switches allow VMs to communicate with each other and with the external world. Hyper-V supports different types of virtual switches—external, internal, and private—each tailored for specific networking scenarios and requirements.
How can I optimize performance for my Hyper-V virtual machines?
