2 Agenda Introduction to Virtualization What is HP? OpenS on HP Q & A Configuration (How to configure OpenS as a guest?) Installation of OpenS September 18, 2009

3 Introduction to Virtualization

4 Virtualization 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 VAX M Security Kernel ( Karger et al in IEEE Transactions on Software Engineering 1991 ) Xen, HP for Itanium hardware September 18,

5 Virtualization Advantages of virtual machines Hardware Consolidation Run operating systems where the physical hardware is unavailable Emulate more machines than are physically available Timeshare lightly loaded systems on one host Flexibility Easier to create new machines, backup machines, etc. Software testing using clean installs of operating systems and software Debug problems (suspend and resume the problem machine) Easy migration of virtual machines (shutdown needed or not) September 18,

6 What is Integrity /HP? app1 app2 app1 app1 OpenS guest OS Virtual Machine () 1 HPUX guest OS 2 Windows guest OS 3 Guest OR Virtual Machine () Integrity / HP Hardware HP-UX Memory I/O Physical Node / Host Machine (Integrity Server or npar or blade) September 18,

7 HP Integrity Virtual Machines () Optimum utilization across multiple OS app1 app2 Open S app1 Windows HP Integrity Host app1 Memory Processors HP Integrity hardware app2 HP-UX 11i v3 I/O Runs on any HP Integrity: server, npartition, or blade Up to 20 s per core Virtual machines with shared processors and shared I/O Dynamic resource allocation built in OS fault and security isolation Designed for heterogeneous guests (OpenS, HPUX, Linux and Windows) September 18,

8 Virtual CPUs

9 Dynamic CPU allocation Virtual Machine 1 Virtual Machine 2 Virtual Machine 3 app1 app2 app3 app4 OS app1 OS app2 app1 app2 app3 app4 OS Example: guaranteed 80% CPU allocation Host (Integrity + platform OS) Virtual machines automatically benefit from instant capacity on host Instant Capacity September 18,

10 Virtual CPU s are created with one or more vcpus A single can have as many vcpus as physical cores Maximum of 8 virtual CPUs per Up to 20 vcpus per physical core Changing the number of vcpus in a requires a reboot of the September 18,

11 Virtual CPU Resource guarantee Maximum processing power A resource guarantee (an entitlement ) Entitlements can be set in range of 5% to 100% Entitlements in 1% increments If a is not using its entitlement, other s can use it September 18,

12 Virtual CPU Scheduling Integrity schedules vcpus Scheduling is according to, and guaranteeing a s entitlement Integrity distributes remaining cycles September 18,

13 Sharing of Physical Resources

14 Dynamic I/O Sharing Virtual Server 1 Virtual Server 2 Virtual Server 3 Virtual server s I/O packets directed to I/O cards by Integrity Host (Integrity + platform OS) I/O card can be dedicated to a virtual machine for performance isolation September 18,

15 Dynamic Network Sharing Virtual Machine 1 Virtual Machine 2 Virtual Machine 3 app1 OS Virtual Switch app1 OS app2 Virtual Switch Host (Integrity + platform OS) Logical port either physical (lan) port, or APA port app1 OS app2 Virtual Switch Virtual machine s network packets directed to physical NIC by the Integrity Host Virtual NIC may be defined without a logical port for guest-to-guest communication NIC can be isolated to a virtual machine September 18,

16 Storage Virtualization DVD virtualized on host by: -Physical DVD -File Disk virtualized on host by: - Physical disk - File - Logical volume - SAN Host (Integrity + platform OS) SAN September 18,

17 Guest Migrations

18 Offline virtual machine migration app1 app2 with unique: Kernel Parameters Patch levels Layered software s is stopped on one server and then started up on another app1 app2 OS OS app1app2 OS Host (Integrity + platform OS) SAN Host (Integrity + platform OS) September 18,

19 What is Online Migration? Linux HP-UX OpenS Online (Guest) Migration is a new Integrity feature enabling a running, its OS and its applications to be moved to a different Host system without service interruption. While the is moved from one Host to another Host, the guest OS and all its applications will remain active without an OS reboot or application restart. September 18,

20 Online virtual machine migration continues to operate on source server while migration begins is briefly suspended as final resident memory image transfers continues operation on target server after transfer completes app1 app2 app1 app2 OS app1app2 OS OS with unique: Kernel Parameters Patch levels Layered software SAN Host (Integrity + platform OS) Host (Integrity + platform OS) September 18,
