7 Topic: Managing VMs 16. Mai How do you manage and monitor Integrity Virtual Machines? Command Line Interface Create, modify, delete VMs, console access, and VM status Integrity VM Manager (vmmgr) Visualize resources assigned to VMs Configuration management of VMs Key features Graphical view of virtual to physical network & storage VM configuration including create, modify CPU entitlements, delete, reset, stop, & boot View all VMs in a host, including utilization information Available from HP-UX host System Management Homepage & seamless integration with VSE manager 16.

10 Integrity VM Manager Storage Visualization 16. Mai Servers Storage Network Software Challenge: Enterprises have unused server capacity yet still can t meet demand Tremendous amount of unutilized capacity Server Average Utilization Utilization at an actual HP customer Servers Most reports put average utilization at approx 30% Yet these systems are unable to handle the load 16.

11 Easy portability of VMs for fast offline deployment and migration app1 app2 VM with unique: Kernel parameters Patch levels Layered software VMs can be stopped on one server and then started up on another with no changes app1 app2 Host (Integrity VM + platform ) app1app2 Host (Integrity VM + platform ) Development system (ex. rx2600-2) QA system (ex. rx ) Recommended setup Symbolic links on each system to VM-accessed disks, physical disk shared between hosts NFS mount to same disk for storage of VM specific runtime info, such as EFI settings, kernel launch options, and IPMI events Movement within the same subnet so IP address can be maintained 16. Mai What can run Where? Host-level utilities and system management tools can be run on the Integrity VM host. These include Utility pricing: Instant Capacity, PPU Monitoring: Diagnostics, Glance, SPIs/agents High-availability software: Auto Port Aggregators, etc. Workload Management: gwlm Platform functions: PCI OL*, Cell OL* (when available) Other, end-user applications cannot be run on the Integrity VM host. Virtual Machines run off-the-shelf operating systems No special release required No patches required Guest Toolkit may be installed providing VM utilities 16. Mai
