This workshop, the first of its kind to deal exclusively with virtual machine security, will tackle the important research topics in virtualization security. Virtualization has seen an explosion in growth in deployment, implementations, and applications. Virtualization holds unique properties that make it attractive for security including isolation, compartmentalization, live state capture, and replay. Virtualization has been used to study malicious software as well as to prevent malicious software infection. In addition, virtualization itself is now the subject of attack. This workshop aims to bring together leading researchers in the fields of virtualization and security to present the latest work on these topics.
