implementations continue to evolve, and they may use more than one technique; therefore, this
implementation list should be considered only as a sample of possibilities.

Integrated hypervisors in ProLiant servers
ProLiant iVirtualization integrates select third-party hypervisors onto ProLiant platforms allowing
customers to quickly set up and manage virtual machines. The first integrated versions available are
VMware ESXi and Citrix XenServer. HP expects to offer an integrated version of the Microsoft Hyper-V
Server hypervisor in late 2009.
The integrated hypervisor solution provides important technologies to administrators:
Easily deploy and manage virtual machines using familiar ProLiant server management tools
Move easily from stand-alone implementations to full enterprise versions of the hypervisor products
Manage virtual machines on a single physical server using a simple graphical user interface, the
ProLiant Virtual Console (currently available only with Citrix XenServer)
Use of familiar HP management tools
The integrated hypervisor solution models the virtual machine as an extension of the physical server,
allowing ProLiant customers to easily deploy and manage a virtual machine 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 the SNMP agents and uses Web-based
enterprise management WBEM providers instead.

When using the ProLiant-integrated VMware ESXi,
the WBEM providers in HP SIM are pre-installed along with VMware ESXi. This method of distributing
virtual machine technology removes time-consuming installation steps, simplifies host configuration,
