HP Integrity Virtual Machines

optimum 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—

Dynamic I/O sharing networking

Host (Integrity VM + platform OS)

• 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

capacity yet still can’t meet demand

Most reports put average utilization at approx 30%

Tremendous

app1 app2

Host (Integrity VM + platform OS) OS app1 app2 VM with unique: • Kernel parameters • Patch levels • Layered software OS app1app2 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
