A Survey of Virtualization Technologies With Performance Testing

Virtualization has rapidly become a go-to technology for increasing efficiency in the data center. With virtualization technologies providing tremendous flexibility, even disparate architectures may be deployed on a single machine without interference. Awareness of limitations and requirements of physical hosts to be used for virtualization is important. This paper reviews the present virtualization methods, virtual computing software, and provides a brief analysis of the performance issues inherent to each. In the end we present testing results of KVM-QEMU on two current Multi-Core CPU Architectures and System Configurations. Keywords-Virtual Computing, Isolation, Security
