HP Insight Control Virtual Machine Management 7.3 User Guide

2 Key concepts
Heterogeneous environment
A heterogeneous environment hosts virtualization layers, such as VMware ESX, Hyper-V, and so
on. Insight Control virtual machine management supports heterogeneity by providing a uniform
way to access and manage all the hypervisors. For information about the supported hypervisors,
see the HP Insight Management Support Matrix available at www.hp.com/go/insightcontrol/docs.
Virtual machine
A virtual machine is software running on a physical machine, which shares all the resources of the
host machine and has its own operating system.
Virtual machine host
A host machine is a system with a hypervisor installed on it to host virtual machines. A host machine
can have more than one virtual machine hosted on it.
Virtual machine guest
A virtual machine guest is a virtual machine running on a virtual machine host.
Handling prefailure alerts
Systems Insight Manager can detect certain prefailure alerts and generate corresponding events.
Insight Control virtual machine management uses VMotion for VMware ESX and Live Move capability
for Microsoft Hyper-V R2 servers as event handlers for these events, so that the virtual machine can
be moved to an alternate host before the system fails or is placed in maintenance mode.
The prefailure events handling feature is supported in the following virtual machines on shared
storage:
• VMware ESX, where the ESX host is enabled for VMotion.
• Microsoft Windows Server 2008 R2 Hyper-V, Microsoft Windows 2012 R2 Hyper-V, Microsoft,
and Windows Server 2012 Hyper-V, where the virtual machines are HA-enabled and powered
on.
NOTE: Xen does not support PFA.
