1.1 About HP Integrity Virtual Machines
Integrity Virtual Machines is a soft partitioning and virtualization technology that provides
operating system isolation, with sub-CPU allocation granularity and shared I/O. Integrity VM
can be installed on an Integrity server or hardware partition (nPartition) running HP-UX. The
Integrity VM environment consists of two types of components:
• VM Host
• Virtual machines (also called guests)
The VM Host virtualizes physical processors, memory, and I/O devices, allowing you to allocate
them as virtual resources to each virtual machine.
Virtual machines are abstractions of real, physical machines. The guest operating system runs
on the virtual machine just as it would run on a physical Integrity server, with no special
modification. Integrity VM provides a small guest software package that aids in local management
of the guest's virtual machine.
