instance. If no such parameters are specified, the values are |
| 128 | 129 |
inherited from the cluster. Possible parameters are: |

denote the unit, otherwise the value is taken in mebibites |

The possible hypervisor options are as follows: |

|
|

|
|
| 156 | 153 |
boot\_order |

Valid for the Xen HVM and KVM hypervisors. |

The ``-O`` (``--os-parameters``) option allows customisation of the OS |
|
| 412 |
parameters. The actual parameter names and values depends on the OS |
|
| 413 |
being used, but the syntax is the same key=value. For example, setting |
|
| 414 |
a hypothetical ``dhcp`` parameter to yes can be achieved by:: |
|
| 415 |
|
|
| 416 |
gnt-instance add -O dhcp=yes ... |

The ``--iallocator`` option specifies the instance allocator plugin |
| 415 | 420 |
to use. If you pass in this option the allocator will select nodes |
| 416 | 421 |
for this instance automatically, so you don't need to pass them |

| 862 | 868 |
least one of the arguments, otherwise the command complains. |

The ``-H`` option specifies hypervisor options in the form of
|
|
| 865 |
name=value[,...]. For details which options can be specified, see
|
|
| 866 |
the **add** command. |
|
| 870 |
The ``-H``, ``-B`` and ``-O`` options specifies hypervisor, backend
|
|
| 871 |
and OS parameter options in the form of name=value[,...]. For details
|
|
| 872 |
which options can be specified, see the **add** command.

The ``-t`` option will change the disk template of the instance. |

Currently only conversions between the plain and drbd disk templates |

The ``--select-os`` option switches to an interactive OS reinstall. |
| 913 | 919 |
The user is prompted to select the OS template from the list of |
| 914 |
available OS templates. OS parameters can be overridden using |
|
| 915 |
``-O``.

(more documentation for this option under the **add** command).

| 916 | 922 |
|
| 917 | 923 |
Since this is a potentially dangerous command, the user will be |
| 918 | 924 |
required to confirm this action, unless the ``-f`` flag is passed. |
