April 12, Agenda What is virtualization? What is HPVM? Configuring and starting an OpenVMS Guest

April 12, Virtualization in General Virtual machines run in software that emulates computer hardware −Host machine – hardware running the virtual machine software −Host operating system – operating system running the virtual machine software −Hypervisor – slimmed down host operating system that virtualizes the physical hardware −Guest system – operating system Examples of Virtual Machines −Simh, Charron VAX for VAX hardware −Personal Alpha for Alpha hardware −Virtual PC, Boot camp, VMWare, Hyper-V for x86/x64 hardware, HPVM for Itanium hardware

April 12, Virtualization in General Advantages of virtual machines −Run operating systems where the physical hardware is unavailable −Easier to create new machines, backup machines, etc. −Software testing using “clean” installs of operating systems and software −Emulate more machines than are physically available −Timeshare lightly loaded systems on one host −Debug problems (suspend and resume the problem machine) −Easy migration of virtual machines (shutdown needed or not)

April 12, HPVM history Started with 1 engineer in 2000 Added 2 engineers in 2002 Team organized in end of 2003 November 2005 – first boot of OpenVMS as a guest HP goal - allow HPVM guests to migrate from one host to another without rebooting

April 12, What is Integrity VM? VM 3 VM 2 Virtual Machine (VM) 1 I/O Memory Hardware Integrity VM Host Windows guest OSLinux guest OS OpenVMS guest OS app1app2app1 Terms and Acronyms:  VM Host or Host  VM  Guest OS  Guest  Physical Node: a single server or nPar

April 12, Sub CPU virtual machines with shared I/O Runs on a server or within an nPar Dynamic resource allocation built in Resource guarantees as low as 5% CPU granularity Resource guarantees as high as 100% of 4 CPU’s OS fault and security isolation Supports all (current and future) HP Integrity servers Designed for multi OS −HP-UX 11i v2/v3 guests −Windows 2003 guests −Linux guests −OpenVMS guests in future Integrated with VSE HP Integrity Virtual Machines Optimum utilization across multiple OS HP-UX 11i v3 app1app2 VM Host Memory Hardware I/O Windows app1 Linux (Suse) HP-UX 11i v2 app1app2 app1 Linux (Redhat)OpenVMS app1

April 12, Dynamic I/O and Network Sharing Host (Integrity VM + platform OS) Virtual server’s I/O packets directed to I/O cards by the Platform Manager Virtual Server 1 Virtual Server 2Virtual Server 3 I/O card can be dedicated to a virtual machine for performance isolation

April 12, Dynamic I/O and Network Sharing Host (Integrity VM + platform OS) Virtual machine’s network packets directed to physical NIC by the Integrity VM Host NIC can be isolated to a virtual machine Virtual Machine 2 app1app2 OS Virtual Machine 3 Virtual Machine 1 OS app1 Virtual NIC may be defined without a logical port for guest-to-guest communication Virtual Switch OS app1 app2 Logical port – either physical (lan) port, or APA port

April 12, I/O Virtualization and Integrity VM Host (Integrity VM + platform OS) SAN DVD virtualized on host by: -Physical DVD -File Disk virtualized on host by: - Physical disk - File - Logical volume - SAN

April 12, ServiceGuard – clustering in the host Host A Host B VM host (SG node) VM host (SG node) OpenVMS guest

April 12, HP-UX 11i v3 host AVIO for “other” guests OpenVMS guest On-Line guest migration More and bigger Enhanced performance Integrity VM futures, sooner or later

April 12, Configuring an OpenVMS Guest Configuring by Virtual Machine Manager - an HP SIM plug-in Configuring by HP-UX commands
