This page describes how the '''stoney conductor Lean Provisioning''' works.

## Step II: Set the '''Virtual Machine Data''':
##: Set the '''Virtual Machine Pool''': <font color="green">vm-template-virtual-machine-pool-01</font>
##: Set the '''Virtual Machine Node''': <font color="green">foss-cloud-node-01.tombstonestepping-stone.ch</font>##: Display the '''Virtual Machine Name''': <font color="green">kvm-0001.tombstonestepping-stone.ch</font> (read only, created by the vm-manager)
##: Set the '''Virtual Machine Description''': <font color="green">Gentoo Linux 2013.0 Template</font>
##: Display the '''Virtual Machine Operating System''': <font color="green">Linux</font> (read only, taken from the virtual machine profile)
# Install the '''Virtual Machine Template''' with the chosen operating system.
#: The administrator can now install the operating system on the virtual machine template.
#: As the last step, the administrator executes the sysprep script in the virtual machine template (this makes sure, that virtual machine template is in a sane state and is shut down).
#: The administrator releases the freshly installed virtual machine template in the vm-manager: <font color="green">ready for use</font>
# Create the '''Persistent Virtual Machine''':
#: Choose the '''Persistent Virtual Machine Pool''': <font color="green">persistent-virtual-machine-pool-01</font>
#: Choose the '''Virtual Machine Node''': <font color="green">foss-cloud-node-02.tombstonestepping-stone.ch</font> (this choice depends on the Persistent Virtual Machine Pool)#: Display the '''Persistent Virtual Machine Name''': <font color="green">kvm-0002.tombstonestepping-stone.ch</font> (read only, created by the vm-manager)
#: Set the '''Virtual Machine Description''': <font color="green">Django Server for Customers</font>
#: Set the '''Persistent Virtual Machine Type''': <font color="green">Server</font>
#: Choose the '''Software Stack''': <font color="green">Django (Version 1)</font> or <font color="green">Django (Version 2)</font> (display this field only if one or more software stacks relevant for the chosen operating system, type and version exist, otherwise disable (grey listing))
#: Choose the '''Persistent Virtual Machine Environment''': <font color="green">Test</font>, <font color="green">Development</font> or <font color="green">Production</font> (display this field only if one or more environments exist for the chosen software stack, otherwise disable (grey listing))
#: Choose the '''Reseller''': for example <font color="green">stepping stone GmbH</font> (preselect the reseller of the currently logged-in user)
#: Choose the '''Customer''': for example <font color="green">stepping stone GmbH</font> (preselect the customer of the currently logged-in user)

== Notizen Releasing a virtual machine template ==The user must release the virtual machine template:* Unterscheidung zwischen einmaliger Installation und wiederkehrend? Ist für uns interessant, wenn wir Sachen automatisch aufsetzen wollen, jedoch nicht monatlich verrechnen können.This is done by setting the attribute <code>sstVirtualMachineMode</code> from '''first installation''' to '''ready for use'''
Possible values for the <code>sstVirtualMachineMode</code> attribute are:* Installation durch Puppet (kein Maintenance)'''do not use''': Einmalige Kostenvirtual machines can not be created from this virtual machine template. Meaning an undefined state and the administrator must look into the situation.* Installation durch Puppet (mit Mainteenance)'''maintenance mode''': Keine einmaligen Kostenvirtual machines can not be created from this virtual machine template. This mode is used to update the virtual machine template.* '''first installation''': virtual machines can not be created from this virtual machine template, dafür wiederkehrende Kostenthis is the default mode after a fresh virtual machine template creation.* '''ready for use''': the administrator can not start this virtual machine. If he wants to start the virtual machine template,he must set the mode to '''maintenance mode'''.If the <code>sstVirtualMachineMode</code> attribute does not exist, this must have the same meaning as '''do not use'''. To achieve a '''self healing''' effect, the [[VM-Manager]] must set <code>sstVirtualMachineMode</code> to '''do not use'''.

== Notes / Questions ==
Do we make a difference between the first installation and the recurring updates (maintenance)? This question is interesting for providers who want to install a virtual machine automatically, but do not want to be in charge of the recurring updates.
Possible options are:* Installation through Puppet (no maintenance): initial set up fee, no recurring costs.* Installation through Puppet (with maintenance): no initial set up fee, with recurring costs. = Links = [[Category:stoney conductor]][[Category:Lean Provisioning]]
