How to determine Linux guest VM virtualization technology

Originally published at: https://www.cyberciti.biz/faq/linux-determine-virtualization-technology-command/

I have a cloud-based virtual machine running Ubuntu and CentOS Linux server. It may or may not be virtualized. How do I determine what kind of virtualization technology (VMWARE/ KVM/ XEN/ VirtualBox/ Container/ lxc/Hyper-V etc.) a Linux guest system running on? How do I find out the virtualization type of a CentOS 7 Linux VPS?

Tu peux utiliser cette commande :

# dmidecode -s system-manufacturer
    VMware, Inc.
# dmidecode -s system-product-name
   VMware Virtual Platform

Thanks I will add those two commands soon too.
