KVM & OpenVZ virtualization based IaaS open source cloud virtualization platforms: OpenNode, Proxmox VE

The evolution of cloud computing over the past few years is one of the major advances in the history of computing. OpenNode Virtualization Platform is an open source CentOS based server virtualization and management solution, and Proxmox VE is a tweaked Debian distribution with a custom optimized kernel. The two platforms are highly identical, but they are based on distinct Linux distributions, and there are minor differences. In this paper these two open-source IaaS systems are analyzed as KVM & OpenVZ based virtualization solutions.
