Libvirt is open source software that is on KVM and many other hypervisors to provide
low-level virtualization capabilities that interface with KVM through a CLI called virsh. A list
of virsh commands can be found in the Table F-2 on page 517

Virsh is the main CLI for libvirt for managing virtual machines. A complete list of supported
virsh commands in KVM for IBM z with detailed descriptions is listed in KVM Virtual Server
Management, SC34-2752.
The Hypervisor Performance Manager (HPM) monitors virtual machines running on KVM
The HPM monitors virtual machines running on KVM to achieve goal-oriented
policy-based performance goals. For more information about HPM, see Getting Started
with KVM for IBM z Systems, SG24-8332.
Open vSwitch (OVS) is open source software that allows for network communication
between virtual machines that are hosted by a KVM hypervisor.

MacVtap is a device driver that is used to virtualize bridge networking and is based on the
mcvlan device driver.

QEMU is open source software that is a hardware emulator for virtual machines that run
on KVM. It also provides management and monitoring function for the KVM virtual
machines.

The installer is a series of windows to assist and guide the user through the installation
process. Each window has setting selections that can be made to customize the KVM
installation. For more information about KVM installation process, see Getting Started with
KVM for IBM z Systems, SG24-8332.
Nagios Remote Plugin Executor (NRPE) can be used with KVM for IBM z. NRPE is an
addon that allows you to run plug-ins on KVM for IBM z. You can monitor resources, such
as disk usage, CPU load, and memory usage. For more information about how to
Action
Creates a virtual server with the unique name specified in the
domain configuration .xml file.
Starts a defined virtual server. Using the --console option grants
initial access to the virtual server console and displays all
messages that are issued to the console.onsole.
Terminate a running virtual server, sending a shutdown signal to
the VM. This allows proper shutdown of an operating system of a
virtual machine (VM).
Immediately terminates a virtual server without any interaction with
the operating system running on a VM.
Deletes the definition of a virtual server from libvirt.
Without an option, this lists the running virtual servers. With the
--all option, this command lists all of the defined virtual servers.
Opens the libvirt internal definition of a VM and allows it to be
changed. These changes are not applied dynamically. Instead,
they become effective after a restart of the VM.
