What it does? It can do the following actions: show, boot, shutdown, status and monitor.
Howto use it
Example, to get monitor's help:
kvm-admin my_guest monitor help
To get the command printed:
kvm-admin my_guest show
Boot a guest:
kvm-admin my_guest boot
It's add a bridge to a given bridge from guest configuration file.
The bridge(s) have to exists. There can individual bridges on the system and each guest can assign to different bridge. No need to add many script files and scriptdown files. This is set automaticly.
Configuration File Format
The guest configuration file has to be placed in the directory 'domains'. The format is taken 1:1 from the command line.
To use an qemu-kvm option which doesn't have a parameter, have to use:
variable = enabled
Global configuration variabales, which all guest should effected, can write in 'config/kvm.cfg' file.
# have to set the path to qemu-kvm executable qemu-kvm = /usr/bin/kvm
daemonize = enabled localtime = enabled
name = my_guest smp = 2 m = 1024 # first drive drive = file:/path_to_image_or_lvm,[and other options] # second drive drive = file:/path_to_image_or_lvm,[and other options] cdrom = my_installer.iso daemonize = enabled localtime = enabled
Only one exception exists. This is only for the '-net tap' option. There have to add an option for the bridge.
An example for tap option when using '-net nic':
# first network interface net = nic,[and other options] net = tap,ifname=my_iface_one,bridge=br0 # second network interface net = nic,[and other options] net = tap,ifname=my_iface_two,bridge=br1

Please read the README for further information.
To run the kvm process under a unprivileged user.
Add an user 'kvm' for example and add this in the guest configuration file.
runas = kvm
For each guest can assign an individual user.
When all guests should run as the user 'kvm' then add this in the global configurations file 'config/kvm.cfg'
runas = kvm
When is set in 'config/kvm.cfg' the guest configuration file does override it, when there also is set.
runas = kvm_one
Then this process is running as user 'kvm_one'
* build a init script * build an installation routine * add possibility to automatic create and delete guest
The ordinary fixes :)
