Use virt-what to Get VPS Virtualization Technology

VPS has a variety of virtualization technologies. Common VPS virtualization architectures are VMWare, Hyper-v, OpenVZ, Xen, and KVM. We can use the "virt-what" tool to judge and refer to our own VPS virtualization architecture. Now Lets take a look those popular main Cloud Vendor's Virtualization technology. virt-what is a shell script which can be used to detect if the program is running in a virtual machine. Virt-what supports a very large number of different hypervisor types, including common open source hypervisors (KVM, Xen, QEMU, VirtualBox), mainframe systems like IBM Systemz, LPAR, z/VM, hardware partitioning schemes like Hitachi Virtage, proprietary hypervisors like VMWare, Microsoft Hyper-V and much more.. 

It supports following virtualization platforms:
VMware、Hyper-V、VirtualPC、VirtualBox、OpenVZ / Virtuozzo、Linux-VServer、UML、IBM PowerVM Lx86 Linux/x86 emulator、Hitachi Virtualization Manager (HVM) Virtage logical 、partitioning、IBM SystemZ、Parallels、Xen、QEMU/KVM


Here are some running examples:

The program prints out a list of facts about the virtual machine, derived from heuristics. One fact is printed per line.

# virt-what xen xen-domU

# virt-what kvm

# virt-what (nothing printed ⇒ baremetal)

Method 1: Compile it from code

1. Download tool

wget https://people.redhat.com/~rjones/virt-what/files/virt-what-1.20.tar.gz

2. Installation

tar zxf virt-what-1.20.tar.gz   #untar the download file
cd virt-what-1.11               #enter the directory
./configure                     #configure it using default settings
make && make install            #compile and get executable file

3. View

virt-what

Method 2: Download it and Run

Mostly, it has been installed in to your VPS. If not, you can use 'yum install virt-what -y' or 'apt-get install virt-what' to get it installed.
