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>info</command>
90 This command will list detailed information about each OS
91 available in the cluster, including its validity status, the
92 supported API versions, the supported parameters (if any) and
93 their documentations, etc.
97 <command>modify</command>
98 <arg>-H <replaceable>HYPERVISOR</replaceable><arg>:<arg choice="plain" rep="repeat">option=<replaceable>value</replaceable></arg></arg></arg>
99 <arg choice="req"><replaceable>OS</replaceable></arg>
103 This command will allow you to modify OS parameters. At the moment
104 we just support per-os-hypervisor settings. You can run modify
105 <option>-H</option> with the same syntax as in
106 <command>gnt-cluster init</command> to override default hypervisor
107 parameters of the cluster for specified
108 <replaceable>OS</replaceable> argument.
112 Note: The <replaceable>OS</replaceable> doesn't have to exists.
113 This allows preseeding the settings for
114 <replaceable>OS</replaceable>es not yet known to
115 <command>gnt-os</command>.
