The &dhpackage; is used for managing the list of available operating system flavours for the instances in the ganeti cluster. list Gives the list of available/supported OS to use in the instances. When creating the instance you can give the OS-name as an option. diagnose This command will help you see why an installed OS is not available in the cluster. The list command shows only the OS-es that the cluster sees available on all nodes. It could be that some OS is missing from a node, or is only partially installed, and this command will show the details of all the OSes and the reasons they are or are not valid. modify -H HYPERVISOR:option=value OS This command will allow you to modify OS parameters. At the moment we just support per-os-hypervisor settings. You can run modify -H with the same syntax as in gnt-cluster init to override default hypervisor parameters of the cluster for specified OS argument. Note: The OS doesn't have to exists. This allows preseeding the settings for OSes not yet known to gnt-os. &footer;
