![]() Vendor: QEMU Model: QEMU DVD-ROM Rev: 0.9. If it's KVM the /proc/scsi/scsi and ethtool options show up as follows: SCSI $ cat /proc/scsi/scsi A 0 means it's a VM, a 1 means it's a physical system. If you're on Ubuntu/Debian there's the package open-vm-tools can be installed. $ sudo lshw -class systemĬapabilities: smbios-2.4 dmi-2.4 vsyscall64 vsyscall32Ĭapabilities: smbios-2.5 dmi-2.5 vsyscall32 This command produces the following output on vairous VM technology guests. Virtualization Technology: QEMU ls -1 /dev/disk/by-id/ If you don't have the rights to run dmidecode then you can use: On bare metal, this returns an identification of the computer or motherboard model. Microsoft VirtualPC dmidecode | egrep -i 'manufacturer|product' Qemu (emulated) dmidecode -s system-product-name Qemu with KVM dmidecode -s system-product-name VirtualBox dmidecode -s system-product-name VMware Workstation dmidecode -s system-product-name Others have added additional platforms that they're familiar with as well. ![]() I have tested on Vmware Workstation, VirtualBox, QEMU with KVM, standalone QEMU with Ubuntu as the guest OS. I'm mostly interested in Linux, but if it also works for other unices that's nice. What's the easiest way of determining what virtualization technology this system may be a guest of? I'd appreciate if proposals mentioned which technologies (including bare hardware) can be conclusively detected and which can be conclusively eliminated. Ideally, it would be something like lshw: an easily-installable (if not preinstalled) command that does the poking around and prints out relevant information. So I have to convey instructions like “copy-paste this command” and not “poke around /proc somewhere”. More precisely, I'm helping someone diagnose the issue, I'm not sitting at the helm. This isn't a hostile environment: I'm not trying to work against a VM that is trying to disguise itself, I'm diagnosing a flaky server that I know little about. ![]() I want to determine what kind of virtualization technology it runs on, if any (VMWare, VirtualBox, KVM, OpenVZ, Xen, ). These latter features may be used to override decisions made by apt-get's conflict resolution system.I have command line access to a Linux machine which may or may not be virtualized. Similarly a plus sign can be used to designate a package to install. If a hyphen is appended to the package name (with no intervening space), the identified package will be removed if it is installed. The /etc/apt/sources.list file is used to locate the desired packages. All packages required by the package(s) specified for installation will also be retrieved and installed. Each package is a package name, not a fully qualified filename. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.Īpt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.Īpt-get install is followed by one or more packages desired for installation or upgrading. ![]() More information about install using apt-getĪdvanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. ![]()
