What it does? It offer the possibility to manage a qemu-kvm domain via commandline.
Howto use it
Example, to get monitor's help:
kvm-admin monitor my_domain
To get the command printed:
kvm-admin show my_guest
Boot a guest:
kvm-admin boot my_guest
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 qemu-kvm domain configuration file are placed in the directory 'domains'. The format is taken 1:1 from the command line but separated by new line
To use an qemu-kvm option which doesn't have a parameter you have to use:
variable = enabled
Global configuration variabales which all qemu-kvm domains should effected, can write in 'config/kvm.cfg' file.
# have to set the path to qemu-kvm or name # the script generate-kvm-option does update the path qemu-kvm = kvm, qemu-kvm
daemonize = enabled localtime = enabled
Example output for a qemu-kvm domain:
# if name is not set it will use the filename as name 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,bridge=br0 # second network interface net = nic,[and other options] net = tap,bridge=br1

Please read the README for further information.
To run the kvm process under a unprivileged user.
Add an user 'kvm' and add this in to the qemu-kvm domain configuration file.
runas = kvm
For each qemu-kvm domain you can assign an individual user.
When all qemu-kvm domains 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 qemu-kvm domain configuration file can override it.
* extend the installer script * build a init script * build an installation routine * add possibility to automatic create and delete guest
The ordinary fixes :)
