imvirt - I'm virtualized?

Description

This little perl script tries to detect if it is called from within a virtualization container. This is detected by looking for wellknown boot messages, directories and reading DMI (Desktop Management Interface) data.

The following containers are detected:

Virtual PC/Virtual Server
VirtualBox
VMware
QEMU/KVM (experimental)
Xen (para and non-para virtualized)
OpenVZ/Virtuozzo
UML
any HVM providing CPUID 0x40000000 detection

The tool will print exactly one line. The result has the following meaning:

Line	Detected container
HVM: <signature>	signature of an unknown hypervisor*
VirtualBox	VirtualBox
Virtual Machine	Microsoft Virtual PC/Virtual Server
VMware	VMware Virtual Platform
VMware (Express\|ESX Server\|GSX Server\|Workstation)	VMware Virtual Platform*
OpenVZ	OpenVZ/Virtuosso*
Physical	This is a physical machine or a not detected container.
QEMU	QEMU/KVM (based)
UML	User Mode Linux*
Xen	Xen hypervisor
Xen 3.x (PV\|HVM)	Xen hypervisor*

*) available since imvirt 0.3
