![]() ![]() I used the code below on a machine running under KVM. The easiest way to check if the OS is running on a virtual machine is to check for the presence of the hypervisor cpu flag in /proc/cpuinfo. The top command displays Linux processes and has a column that details how the processes are utilizing available/allocated CPU. VMware Workstation, VMware Player, VirtualBox, Parallels Desktop for Mac and QEMU are examples of type-2 hypervisors. For more details, you can check the cpuinfo file. These hypervisors abstract the guest operating systems from the host operating system. A guest operating system runs as a process on the host. It uses the Linux kernel’s virtualization capabilities to provide virtualization at the hardware level, allowing it to run multiple guest operating systems simultaneously. Type-2 hypervisors run on a conventional operating system just as other computer programs do. Kvm is a type-2 hypervisor for Linux that enables the creation of virtual machines on a Linux host. KVM, Citrix XenServer, Microsoft Hyper-V and VMware ESX/ESXi are some exmaples of Type-1 hypervisors. Type-1 hypervisors run directly on the host’s hardware to control the hardware and to manage guest operating systems. Type-1: native or bare-metal hypervisors.A hypervisor is a piece of computer software, firmware or hardware that creates and runs virtual machines. Not sure if there is a one tool that can print all the information, but the tools I mentioned are installed by default and in Linux/Unix we usually have one tool for one thing (see Unix Philosophy).Objective: Determine if OS is running on a virtual machine.īefore we start, let’s look at some basic stuff. df -h: mounted filesystem with size and free space./proc/cpuinfo (file): detailed CPU information.cat /proc/cpuinfo vendorid : IBM/S390 processors : 1. But KVM brings more benefits compared to other virtualisation technologies. Issue the following command to find out whether you can operate your Linux instance as a hypervisor. Since KVM is part of Linux, it installs natively, enabling straightforward user experience and smooth integration. Static hostname: vtrefny-Standard-PC-Q35-ICH9-2009 The main benefit of the KVM hypervisor is its native availability on Linux. Information about operating systems other than Linux. I'm not using Windows, so I'm not sure what can systeminfo do, but here are few commands based on screenshots I googled.īasic system information: hostnamectl $ hostnamectl The goal of the Hypervisor Tuning Guide (HTG) is to provide cloud operators. +sssssssssssssssssyyyssss+- Memory: 10264MiB / 32061MiB ssssssssssshdmNNNNmyNMMMMhssssss/ CPU: Intel i7-8700K (12) 4.700GHz +sssssssssdmydMMMMMMMMddddyssssssss+ Terminal: tilix sssssssshNMMMyhhyyyyhdNMMMNhssssssss/ Icons: Yaru +sssshhhyNMMNyssssssssssssyNMMMysssssss+ WM Theme: Adwaita OssyNMMMNyMMhsssssssssssssshmmmhssssssso WM: Mutter ![]() OssyNMMMNyMMhsssssssssssssshmmmhssssssso DE: GNOME +sssshhhyNMMNyssssssssssssyNMMMysssssss+ Resolution: 2560x1440 sssssssshNMMMyhhyyyyhmNMMMNhssssssss/ Packages: 3626 (dpkg), 15 (snap) +ssssssssshmydMMMMMMMNddddyssssssss+ Uptime: 7 hours, 20 mins ssssssssssshdmmNNmmyNMMMMhssssss/ Kernel: 5.4.0-52-generic +ssssssssssssssssssyyssss+- OS: Ubuntu 20.04.1 LTS x86_64 ![]()
