Summary


Many changes have occurred in operating system and computer hardware technology since the Compatible Time Share System was developed in the early 1960s. The CTSS operating system formed the foundation for time-sharing systems that are prevalent today. In many ways, Integrity Virtual Machines take the fundamental ideas developed decades ago on the CTSS and provide a virtualized platform for running multiple operating systems simultaneously on the same hardware. Just as the CTSS allowed a single hardware platform to be used by multiple users at the same time, Integrity Virtual Machines allows a single hardware platform to host multiple operating systems. The result is dramatically higher system utilization and greater workload isolation. Additionally, VMs using Integrity Virtual Machines can more easily be migrated from one hardware platform to another without modification because the resources are virtualized.

This chapter began with an architectural overview of Integrity Virtual Machines and the most common terminology the software uses. Then an example scenario was discussed that demonstrated the administration of Integrity Virtual Machines. The example showed the power and flexibility in creating virtual machines that are capable of sharing CPU, networking, and storage resources.

Integrity Virtual Machines fulfills a crucial role in HP's Virtual Server Environment. The ability to run workloads in isolated environments with the flexibility to migrate VMs from one hardware platform to another is extremely powerful. When combined with the full suite of products in HP's Virtual Server Environment such Global Workload Manager, the end result is a highly available virtualized computing platform that results in a high degree of resource sharing and utilization.
