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.

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
# virt-what
# 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
