VPS Hosting providers at home and abroad are mostly based on Xen, OpenVZ, KVM, Hyper-V, VMware five virtualization technologies.One, Xen official website: http://xen.org/Developed by the University of Cambridge, Xen is a hardware-based, fully segmented, resource-only resource that can be allocated on a physical basis, making it difficult to sell over. Can be divided into XEN-PV (semi-virtualized), and XEN-H
