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. Table 1. Common vendor implementations of virtual machines Virtualization technique Examples of vendor implementations CPU binary translation VMware ESX Hosted-OS, application-layer abstraction Microsoft Virtual Server 2005 R2 VMware Server (formerly VMware GSX) Vendor URLs www.vmware.com www.microsoft.com/virtualserver www.vmware.com/products/server Hardware-assisted virtualization (full virtualization) Paravirtualization Hosted-OS, kernellayer abstraction Citrix XenServer Windows Server 2008 Hyper-V Citrix XenServer Red Hat Enterprise Linux SUSE Linux Enterprise Red Hat Kernel Virtual Machine www.citrix.com/Xenserver http://www.microsoft.com/windowsser ver2008/en/us/hyperv.aspx www.citrix.com/Xenserver www.redhat.com/rhel/ www.novell.com/linux/ www.redhat.com/promo/qumranet/ 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.4 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, 4 For more information about VMware ESXi, see the technology brief titled ―HP VMware ESXi management environment,‖ available at http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01570108/c01570108.pdf 5
