1 OpenNebula - Feature #2395 Provide windows guest contextualization scripts 10/21/ :31 AM - Tino Vázquez Status: Closed Start date: 10/21/2013 Priority: Normal Due date: Assignee: % Done: 0% Category: Context Estimated time: 0.00 hour Target version: Release 4.8 Resolution: fixed Pull request: Description Provide means to contextualize (at least networking) Windows based virtual machines. The best way would be to base the contextualization scripts on [1]. Comments in the users list by Martin Alfke -- We only assign IP address, hostname and enable RDP Hostname is set as contextualisation variable: HOSTNAME = $name (We use the VM name as fqdn). We now only miss setting the DNS according to contextualisation (we need to split the variable into an array).
