What Is Root Partition?
What's the root of all evil? Not that kind of evil but something that can cause much damage if you are not careful with it. Just ask doctor evil here, and he will tell you the answer, as he did suffer through the pain. The answer is simple: the root partition. The root partition is a type of partition within the Windows Hyper-V virtualization environment that is responsible for running the hypervisor. The root partition enables the execution of primary hypervisor software and manages the machine-level operations of the hypervisor and created virtual machines. The term "root" refers to its importance in relation to other partitions in your computer's operating system. All other partitions are considered sub-partitions or child partitions when compared with this one because they rely on them for their functionality. This means that if you wanted to get rid of your computer's root partition, you would also need to remove any sub-partitions you had created on top of it—which means getting rid of any virtual machines as well! You've seen it, you've heard about it—but you might not know precisely what it is. Today we're going to break down some key concepts about the root partition: what it does and why you need one. First off, the root partition primarily provides logically isolated space for the hypervisor. It requires computing, memory and storage capacity to store and execute the hypervisor. The root partition can access the host machine directly and provide functions such as interfacing with the host machine for device drivers, power management and the addition and removal of devices. The root partition works with the parent partition to create child partitions for all the virtual machines. The root partition is generally considered the parent partition; however, it is actually a logically distributed partition for hypervisor-specific operations.
