![]() ![]() Have you ever wanted to know the details about CPU, memory, or other physical hardware? From time to time it is very handy to be able to gather some of these details from the VMware ESXi command line. Comparison of virtual machines - compares the features of several platform virtual machines.There are times with your virtual infrastructure running on top of VMware vSphere that you need to gather information about the physical servers you are running on.QEMU/Linux guest - describes the setup of a Gentoo Linux guest in QEMU using Gentoo bootable media. ![]() Virt-manager/QEMU_guest - QEMU creation of a guest (VM or container).Virt-manager - desktop user interface for management of virtual machines and containers through the libvirt library.Libvirt/QEMU_guest - covers libvirt and its creation of a virtual machine (VM) for use under the soft-emulation mode QEMU hypervisor Type-2, notably using virsh command.Libvirt/QEMU_networking - details the setup of Gentoo networking by Libvirt for use by guest containers and QEMU-based virtual machines.Libvirt - a virtualization management toolkit.QEMU/QEMU_front-ends - user interface application to the QEMU/libvirt API/library.User:Egberts/Drafts/QEMU - a generic, open source hardware emulator and virtualization suite.The running kernel supports hardware virtualization when "vmx" is visible in the output. User $ grep -color -E "vmx" /proc/cpuinfo To inspect hardware for virtualization support issue the following command: Next generation system container manager.ĭaemonless container engine for developing, managing, and running OCI Containers on linux. Virtualization system making use of the cgroups feature of the Linux kernel. Tool that facilitates building OCI imagesĬontainer virtualization environment which can establish development or runtime environments without modifying the environment of the base operating system. Wikipedia has more on virtualization this over at Libvirt#Supported Hypervisors. Incorporated into mainstream Linux repository in 2016 UML is a software-assist, Type-2 virtualization. The UML driver for libvirt allows use and management of paravirtualized guests built for User Mode Linux. Also can do Type-2 Virtualization which does not support Microsoft Windows as a guest OS Ĭross-platform virtualization software that allows users to run guest operating systems inside a Virtualbox host operating system.īhyve, the "BSD hypervisor" is a hypervisor/virtual machine manager available on FreeBSD, macOS, and Illumos. Type-1 Virtualization supports Microsoft Windows as a guest OS. Native, bare-metal, hypervisor that allows multiple distinct virtual machines (referred to as domains) to share a single physical machine. sells a variety of closed-source hypervisors. More frequently denoted as qemu and not qemu/tcg so often. QEMU is also broken out by its supported accelerators add-ons as well as its default software-emulation mode. There is a comparison table of virtualization software that can handle virtual machines and containers. This combination has been called "hybrid virtualization" CPU VT flag enables direct execution of binary code.īy mitigating some performance hit, guest drivers are deployed to replace the direct-PCI drivers and allow multiple guest to share the same host devices.Hardware-assisted virtualization provides virtual machines with high performance because the physical CPU is partly mapped directly to the virtual CPU (vCPU) machine codes within guest VM are directly executed on host CPU. (Pure) hardware-assisted (native) virtualization use of machine code translator ( qemu/tcg, ( VMware Workstation Hybrid hardware-assisted virtualization.(Pure) hardware-assisted ( native) virtualization.Software-assisted virtualization (also known as software-based emulation or software emulation).Type-2 hypervisor subcategories are broken down into: Type 1 hypervisors provide a higher level of performance as there is no overhead from the interaction of the hypervisor with the guest OS. Type-2 hypervisors are installed on top of an operating system.Type-1 hypervisors are installed directly on hardware.1.2.3 Hybrid hardware-assisted virtualization.1.2.2 (Pure) hardware-assisted (native) virtualization. ![]()
