SLES - autoyast installation with OVM

Following Oracles Documentation SLES should be supported by Oracle VM, but i didnt found SLES as Option while installing a new virtual server. During our project of moving to Oracle-VM, we wanted to use autoyast-installation of SLES. Our approach was to keep it as simple as possible to create new virtual machines. Cloning with OVM was not a real option, our Linux-Guys tend to prefer new installations rather than cloning. In OVM-Guest Boot-Order-Menue - this is what you get and what you can configure. Everything is clear? Nothing is clear, even the official documentation has not made us very happy with OVM.We want to add some more details here, because our SLES-Installations are performed with autoyast. And here is how we solved it: In Network-Boot-Path, you can type what ever you want, we have to modify the vm.cfg-File manually. Here is a sample file: 

vif = ['mac=00:xx:xx:xx:xx:xx,bridge=103ff836f1']
 OVM_simple_name = 'XXXXX'
 ...
 bootargs = ''
 uuid = '0004fb00-0006-0000-e2a0-b2a0266f7767'
 on_reboot = 'restart'
 cpu_weight = 27500
 memory = 8192
 cpu_cap = 0
 maxvcpus = 2
 OVM_high_availability = True
 ...
 OVM_os_type = 'Oracle Linux 7'
 ...
 OVM_domain_type = 'xen_pvm'

(some not important output removed here) In this file you can customize those 2 lines to install SLES with autoyast: 

bootargs='http://<server.domain>/<path_to_sles11sp4>/ install=http://<server.domain>/<path_to_sles11sp4>/' 
extra="install=http://<server.domain>/<path_to_sles11sp4>/ autoyast=http://<server.domain>/<path_to_sles11sp4/<autoyastfile.xml"



After modifying the vm.cfg directly, Start the VM - SuSE will come up magically! 
After successfull installation, it is required to stop the VM, to click something in 
VM-Configuration and then saving the configuration. Please notice that every change in the 
OVM-Webgui will delete the entrys from vm.cfg and will replace it with the default values.
