Installing KVM (Debian) on VMware

KVM Full Name (kernel-based virtual machine) is an open source system virtualization module that is integrated into the major distributions of Linux since Linux 2.6.20. It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM has become one of the mainstream VMM in academia today. KVM Virtualization requires hardware support (such as Intel VT Technology or AMD V technology). is hardware-based full virtualization. The early days of Xen were software-based simulations of para-virtualization, and the new version was full virtualization based on hardware support. But Xen itself has its own process scheduler, storage Management module, etc., so the code is rather large. The widely circulated business system virtualization software VMware ESX series is a software-based simulation of the full-virtualization. I.
