The document discusses virtualization concepts written by S.P. Siddique Ibrahim of Kumaraguru College of Technology. It describes para-virtualization where the guest operating system is recompiled before installation to act as an interface for the hardware, which somewhat increases performance by minimizing overhead compared to other virtualization methods.

20. Para Virtualization
• Here the guest OS is recompiled before
installation.
• It act as interface of hardware
• This type somewhat increase the performance
• Minimize the overhead
