50 <title>DESCRIPTION</title>
53 The <command>&dhpackage;</command> is used for managing the list
54 of available operating system flavours for the instances in the
60 <title>COMMANDS</title>
63 <command>list</command>
67 Gives the list of available/supported OS to use in the
68 instances. When creating the instance you can give the OS-name
73 <command>diagnose</command>
77 This command will help you see why an installed OS is not
78 available in the cluster. The <command>list</command> command
79 shows only the OS-es that the cluster sees available on all
80 nodes. It could be that some OS is missing from a node, or is
81 only partially installed, and this command will show the details
82 of all the OSes and the reasons they are or are not valid.
86 <command>modify</command>
87 <arg>-H <replaceable>HYPERVISOR</replaceable><arg>:<arg choice="plain" rep="repeat">option=<replaceable>value</replaceable></arg></arg></arg>
88 <arg choice="req"><replaceable>OS</replaceable></arg>
92 This command will allow you to modify OS parameters. At the moment
93 we just support per-os-hypervisor settings. You can run modify
94 <option>-H</option> with the same syntax as in
95 <command>gnt-cluster init</command> to override default hypervisor
96 parameters of the cluster for specified
97 <replaceable>OS</replaceable> argument.
101 Note: The <replaceable>OS</replaceable> doesn't have to exists.
102 This allows preseeding the settings for
103 <replaceable>OS</replaceable>es not yet known to
104 <command>gnt-os</command>.
