Virtualization Part 3 -CPU Virtualization - shashank Jain - Medium
In the previous blog https://medium.com/@jain.sm/virtualization-part-2-memory-virtualization-79b1c804e160 we talked of memory virtualization. In this blog we touch upon CPU virtualization Before we take a peek at CPU virtualization it would be interesting to understand how the protection rings are built into x86 architecture. These rings allow the cpu to protect memory and control privileges as to what code executes at what privilege level. The x86 architecture has a concept of protection rin...

Virtualization Part 2 — Memory Virtualization - shashank Jain - Medium
In the first part we covered basics around virtualization (https://medium.com/@jain.sm/virtualization-basics-dad2f20067e6) In this blog we cover memory virtualization . One of the critical challenges with virtualization is how to virtualize the memory. The guest OS should have the same behaviour as the non virtualized OS. This means that the OS should probably be at least made to feel so that it controls the memory. In case of virtualization the direct access to the physical memory cannot be ...

Virtualization Basics - shashank Jain - Medium
In this series we look at the various aspects of Virtualization and in particular the OS virtualization. We start with a high level introduction to virtualization and then deep dive in further series. The intent here is to understand what a virtual machine means and what is happening under the hoods. With virtual machines, multiple OSes will share the same hardware resources with virtualized representation of each of the resource available to the VM. So a VM can continue to do block operation...
