System-Wide Performance Analysis For Virtualization, Deron Eugene Jensen

Dissertations and Theses

With the current trend in cloud computing and virtualization, more organizations are moving their systems from a physical host to a virtual server.

Although this can significantly reduce hardware, power, and administration costs, it can increase the cost of analyzing performance problems. With virtualization, there is an initial performance overhead, and as more virtual machines are added to a physical host the interference increases between various guest machines. When this interference occurs, a virtualized guest application may not perform as expected. There is little or no information to the virtual OS about the interference, and the current performance tools in …
