Empirical research on Virtualization are Cloud computing relies on virtualization technologies to provide computer resource elasticity and scalability. Despite its benefits, virtualization technologies come with serious concerns in terms of security. Although existing work focuses on specific vulnerabilities and attack models related to virtualization, a systematic analysis of known vulnerabilities for different virtualization models, including hypervisor-based and container-based solutions is not present in the literature. With respect to the performance evaluation for the virtual machine monitor, a variety of guest OS and two well-known test tools are adopted in this study. PassMark PerformanceTest 7.0 (at http://www.passmark.com/download/pt_download.htm) is applied to the test of virtual machine performance for the Windows series guest OS like Windows XP, Windows 7, and Windows Server 2003, and UnixBench 5.1.3 (at http://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz) is employed for Linux series guest OS like Ubuntu

You can look at the following paper:https://www.cs.purdue.edu/homes/bb/cs590/papers/mehdi.pdf

It lists several basic references for virtualization.

Empirical research on Virtualization One technique for improving memory efficiency in virtualized systems is content-based page sharing (CBPS). In CBPS, duplicate blocks of memory (or ‘pages’) are collapsed into a single physical copy, with all duplicate virtual pages pointing back to the single physical page. This adjustment means that unneeded physical pages can be freed, lowering the memory footprint of the application or OS.
