What is a Virtual Machine?
The definition that I give people on the VMware ICM course is as follows.
“From the user’s perspective, a virtual machine is a software platform that, like a physical computer, runs an operating system and applications.”
Great but what do we virtualise, do we virtualise the hardware, the operating system or the applications.
This is my opinion, I consider a virtual machine to be the virtualised hardware; I then take that virtual machine and then install the operating system and applications into that virtual machine as if it was a physical computer.
So VMware Virtual machines have multiple files and I consider that the .VMX file is the virtual machine as the file defines the configuration of the hardware.
In a Hyper-V VM the equivalent file is the .VMC
In both cases I’ll agree with the definition that a Virtual Machine is just a bunch of files.
