power consumption, footprint requirements, and improve resource utilization. This technology brief describes how HP is using virtual machine technology and expanding into other areas of server . These include ProLiant iVirtualization, HP Virtual Connect, logical servers, and HP Insight Dynamics - - Compaq DL360 | Server virtualization technologies for x86-based HP BladeSystem a - Page 3
Figure 1. HP technologies for machine abstraction include Virtual Connect, integrated hypervisors, and integrated management. Software-layer abstraction: virtual machines In a virtual machine environment, a software layer abstracts the physical server hardware and creates one or more virtual machine - Compaq DL360 | Server virtualization technologies for x86-based HP BladeSystem a - Page 4
guest OS is modified to include paravirtualized I/O drivers. The modified guest OS makes calls directly to the virtualized I/O services and other privileged operations, rather than having the hypervisor layer trap and translate all privileged instructions. As a result of the guest OS modification - Compaq DL360 | Server virtualization technologies for x86-based HP BladeSystem a - Page 5
in the same way they deploy and manage a physical server. ProLiant iVirtualization leverages customers' familiar ProLiant server management tools so that any of the hypervisor versions can be managed using HP Systems Insight Manager (HP SIM). For example, in its ESXi hypervisor, VMware removed - Compaq DL360 | Server virtualization technologies for x86-based HP BladeSystem a - Page 6
drivers. HP partnerships with virtual machine solutions suppliers give administrators confidence that they will be deploying their virtual machines on the industry's broadest portfolio of servers, storage, software, and services designed to support machine abstraction.

Unlike a binary translation approach, the hypervisor does not need to trap and translate all privileged layer instructions between the guest OS and the actual server hardware. Instead, the modified guest OS makes calls directly to the virtualized I/O services they support - Compaq DL360 | Server virtualization technologies for x86-based HP BladeSystem a - Page 19
Hosted OS, kernel-layer abstraction Kernel-layer abstraction refers to a technique in which the abstraction technology is built directly into the OS kernel rather than having a separate hypervisor layer.
