I'm pleased to announce the first release of 'virt-what', which is a simple shell script that detects if you are running inside a virtual machine, and prints some "facts" about that virtual machine. This is a frequently requested feature. Home page: http://et.redhat.com/~rjones/virt-what/ Source and RPMs: http://et.redhat.com/~rjones/virt-what/files/ So far we can detect: - Xen - QEMU and KVM (but not distinguish between them) - VMware - Microsoft VirtualPC I'm hoping that people who run or develop other virtualization technology will be able to contribute snippets to detect those. It's worth saying (before Dan Berrange says it anyway) that although people often think they need this sort of feature, in most cases using this script is the WRONG THING. If you need a specific virtualization feature, then add code to your application to detect that feature. eg. If you need to make Xen hypervisor calls, your application should try to open /proc/xen/privcmd. As Dan once put it: A shell script just printing out 'native', 'dom0' or 'domU' is too simplistic to be broadly useful to management applications. The concepts are also ill-defined, eg 'native' as a concept can be a baremetal kernel, or a fully-virtualized guest, or both. 'DomU' does not distinguish full or paravirt. The distinction of 'dom0' vs 'native' is irrelevant in non-Xen virtualization systems (eg KVM).
