#Reprint#Tips for using VPS/Using virt

Regarding the use of VPS, especially Linux system VPS are connected through SSH and managed using commands. Snail actually didn’t know much about the use of VPS at the beginning, so he learned it step by step. Sometimes when I see a better script or a more useful function, Snail will basically write an article to record it, mainly so that he can use it when he needs it in the future. Today I reprinted a relatively easy-to-use technique, which is to quickly detect which virtualization method the Linux system VPS uses. At present, the VPS virtualization technologies we often see include KVM, OpenVZ, XEN, Hyper-V, VMware, etc. (You may also need to compare common KVM/OpenVZ/Xen/Hyper-V/VMware virtualization technologies for oversales). General merchants They will all mark what virtualization architecture they use, but there are also a few merchants who don't. In the future, we can quickly understand the actual virtualization technology used by the VPS we purchased through the method introduced below. The method used below in this article is reproduced from @老leftblog.

1. Install virt-what

Installing virt-what is very simple. It can be solved with a short command. You only need to choose the corresponding command according to your own system.

#CentOS system yum install virt-what -y #Debian/Ubuntu system apt install virt-what -y

2. Execute detection command

virt-what#View the version number of virtual technology command virt-what --version

3. Effect demonstration

Snail specially found two VPSs with different systems and different architectures on hand for testing and demonstration. The renderings are as follows:
