What is a Hypervisor !
A hypervisor, also known as a virtual machine monitor (VMM), is software that allows multiple operating systems to run on a single physical computer simultaneously. It does this by creating and managing virtual machines (VMs), which are isolated environments that 'mimic' the hardware of a real computer. VMware , Virtual box are some of the most popular hypervisors.
Our dear friend Viru is on a journey to understand the hypervisor. Let's see what he discovers. -->
Both Intel and AMD have integrated virtualization support into their modern CPUs.
Intel introduced VT-x technology, previously codenamed Vanderpool , on November 13, 2005, within the Pentium 4 series. The CPU flag indicating VT-x capability is "VMX," which stands for Virtual Machine Extension.
AMD developed its initial generation of virtualization extensions under the codename Pacifica These extensions were initially released as AMD Secure Virtual Machine (SVM) and later rebranded under the trademark AMD Virtualization, abbreviated as AMD-V.
Here are some examples of popular hypervisors:
VMware ESXi: A widely-used enterprise-level hypervisor that provides robust virtualization capabilities for data centers.
Microsoft Hyper-V: Included with Windows Server, this hypervisor is used for running multiple virtual machines on Windows systems.
Oracle VM VirtualBox: A free and open-source hypervisor that allows you to run multiple operating systems on a single physical machine. It's popular for desktop virtualization.
KVM (Kernel-based Virtual Machine): A Linux-based open-source hypervisor that's built into the Linux kernel, making it highly efficient for running virtual machines on Linux hosts.
Xen: An open-source hypervisor that provides a robust and flexible platform for virtualization, used in various cloud services like AWS.
Citrix Hypervisor (formerly XenServer): Based on the Xen hypervisor, it's designed for server virtualization and is popular in enterprise environments.
Parallels Desktop: A hypervisor for macOS that allows users to run Windows, Linux, and other operating systems on their Mac computers.
QEMU: A generic and open-source machine emulator and virtualizer that, when used with KVM, can provide a robust virtualization solution.
