Simple CLI for manipulation VMs through libvirt-daemon

Tool Guide

This tool is supposed to be used as light-weight and easy utility for virtual machines (VM) manipulations.

VM Creation

Create a machine "asgard" with defaults mem, disk and cpu. Machine name must be unique across your host OS.

$ libvirter create asgard
asgard created

Create a machine "noatun" with 2 CPU, 3 Gb drive and 100 Mb of memory use

$ libvirter create -c 2 -m 100 -d 3 noatun
noatun created

Create a "hell" machine using predefined sizes use option -s (size):

$ libvirter create -s tiny hell
hell created

Create a QEMU machine "jotunheim" use option -t (type):

$ libvirter create -t qemu jotunheim
jotunheim created

Create a KVM machine with a random name:

$ libvirter create -t kvm
asdfadf created

VM Status

To get "asgard" machine status call:

$ libvirter status asgard
asgard is running

For a not running machine output will be:

asgard is stopped

If a VM does not exists you will receive following output and non-zero return code:

asgard not found

To get more information about a machine use option -a:

$ libvirter status -a asgard
name: asgard
state: running
type: qemu
cpu: 1
memory: 512 Mb
disk: 3 Gb
uptime: 1h 12m 13s

VM List (TBD)

To get VMs' list in a host OS call:

$ libvirter list
asgard
hell
noatun

Also, it's possible to provide a verbose list:

$ libvirter list -v
name	type	state	cpu	memory	disk	uptime
asgard	qemu	running	1	512	3	1h12m12s
noatun	kvm	stopped	2	1024	5	
hell	qemu	stopped	1	512	1

Note: Some other options can be disscussed later if needed.

VM Deletion

To delete "asgard" machine call:

$ libvirter delete asgard
asgard deleted

VM Starting

To start "asgard" machine call:

$ libvirter start asgard
asgard started

VM Stopping

To stop "asgard" machine call:

$ libvirter stop asgard
asgard stopped

VM Restarting

To restart "asgard" machine call:

$ libvirter restart asgard
asgard restarted
