 We now have to re-configure the VMs boot-sequence to 'local-boot'. To do this, follow the steps below:
-* stop the VM by stopping its server object - Datacentre -> Server -> Select + Stop

 * The stop hook now halts the VM by sending a ACPI-Shutdown Signal to the VMs KVM monitor socket. Since in this stage there is now ACPI service running on the VM the stop action will "force-stop" the VM. This will result in a warning via an error event which can be ignored.

 === Install the 'openqrm-local-vm-client' ===
 Now it is recommended to install the 'openqrm-local-vm-client' on the fresh installed system. For local-installed Virtual Machines (e.g. kvm(local VM), xen(local VM), lxc(local VM), openvz(local VM) which have access to the openQRM network the 'openqrm-local-vm-client' activates the plugin-client-boot-services to allow further management functionality (e.g. application deployment with Puppet, system statistics with Collectd etc). Monitoring and openQRM actions are still running on behalf of the VM Host.
 The 'openqrm-local-vm-client' also automatically makes sure that the 'acpi-support/acpid' package is installed to enable the reboot/restart functionalities of KVM via the VM monitor socket. To install the 'openqrm-local-vm-client' on VM, follow the steps below:

	In this view you can use the 'clone' or 'snap' action to clone or snapshot existing, installed KVM LVM Volumes. The 'clone' action creates a new logical volume and copies the content of the origin over. Snapshotting is using the "copy-on-write" mechanism of LVM which is much more efficient. Actually, a deployed snapshot of a KVM LVM Volume just stores the changes compared to its origin. That means that creating snapshots e.g. per user allows to 'just' store the data which is different per user.

 === Create a new KVM Virtual Machine ===
 Use openQRM's Server Wizard to add a new KVM Virtual Machine. This Wizard works in the same way for physical systems, KVM VMs, Xen VMs, Citrix XenServer VMs, VMware VMs, LXC VMs and openVZ VMs.
-Go to Datacenter -> Server -> Add a new Server
+Go to '''Datacenter -> Server -> Add a new Server'''
 Please give a name for the new server. Easiest is to use the 'generate name' button. Also provide a useful description.
+[[File:Csm 28-openqrm-kvm 8c5381275c.png|none|thumb|390x390px|Provide a name and description]]
 In the Resource-Selection please click on 'new resource'. A resource in openQRM is a logical generic object which is mapped to a physical system or Virtual Machine of any type.
+[[File:Csm 29-openqrm-kvm 6b6f96943a.png|none|thumb|390x390px|Click 'New Resource']]
 On the next page find a selection of different resource types to create. Please choose 'KVM (localboot) Virtual Machine'
+[[File:Csm 30-openqrm-kvm b974b8c45b.png|none|thumb|390x390px|Choose 'KVM (localboot) Virtual Machine']]
 This forwards to the KVM Host selection. Please select the openQRM server for the Virtualization Host of the VM to create
+[[File:Csm 31-openqrm-kvm 3571dd52f4.png|none|thumb|390x390px|Select the openQRM server]]
 On the KVM Virtual Machine Overview please click on 'Add local VM'
+[[File:Csm 32-openqrm-kvm bd73a87977.png|none|thumb|390x390px|Click on 'Add local VM']]
 In the VM add form provide a name for the new VM. Again the easiest is to use the 'generate name' button. There are lots of different parameters which can be configured. Anyway you can go with most of the default selection. Please just make sure the first network card of the VM is connected to the previously created bridge 'br0'
+[[File:Csm 33-openqrm-kvm 2443e46725.png|none|thumb|390x390px|Leave configurations as default]]
-Further down the VM add form please configure the boot sequence of the VM. Select 'iso' and open the Filepicker by clicking on the 'Browse' button. This will open a small new window listing the filesystem of the Virtualization Host. Navigate to '/linuxcoe' and select the previously created LinuxCOE automatic-installation iso iamge. Please notice that the name of the iso image may be different in your setup.
