– Complete software isolation

– Dynamic CPU migration

– Sub-socket granularity (PA-8800)

– Multiple OS images

– Dynamic resource allocation

– Share (%) granularity

– 1 OS image


HP Integrity Virtual Machinesoptimum utilization across multiple OS

• 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

• OS fault and security isolation

• Supports all (current and future) HP Integrity servers

• Designed for multi OS—HP-UX 11i in first release, Win2003 Server in 2H 2006Linux: 2007

Dynamic I/O sharing networking


• Virtual machine’s I/O packets directed to I/O cards by the Integrity VM Host

• Virtual LAN may be defined without a physical NIC for guest-to-guest communication

• I/O card can be dedicated to a virtual machine for performance isolation

Topic:

Managing VMs


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

Challenge: Enterprises have unused server capacity yet still can’t meet demand

Most reports put average utilization at approx 30%

Tremendous amount of unutilized capacity

Yet these systems are unable to handle the load

OS

VM with unique:• Kernel parameters• Patch levels• Layered software

OSapp1app2

VMs can be stopped on one server and then

started up on another with no

changes

Development system(ex. rx2600-2)

QA system(ex. rx8620-32)

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


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 OS 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 OS required• No patches required• Guest Toolkit may be installed providing VM utilities
