Number of VCPUs to set for an instance by default, must be an
integer, will be set to 1 if no specified.
-memory
- Amount of memory to allocate for an instance by default, can be
- either an integer or an integer followed by a unit (M for mebibytes
- and G for gibibytes are supported), will be set to 128M if not
- specified.
+maxmem
+ Maximum amount of memory to allocate for an instance by default, can
+ be either an integer or an integer followed by a unit (M for
+ mebibytes and G for gibibytes are supported), will be set to 128M if
+ not specified.

+ Minimum amount of memory to allocate for an instance by default, can
+ be either an integer or an integer followed by a unit (M for
+ mebibytes and G for gibibytes are supported), will be set to 128M if
+ not specified.
auto\_balance
Value of the auto\_balance flag for instances to use by default,
will be set to true if not specified.
+always\_failover
+ Default value for the ``always\_failover`` flag for instances; if
+ not set, ``False`` is used.
+
The ``-N (--nic-parameters)`` option allows you to set the default nic
parameters for the cluster. The parameter format is a comma-separated
network script it is interpreted as a routing table number or
name.
+The ``-D (--disk-parameters)`` option allows you to set the default disk
+template parameters at cluster level. The format used for this option is
+similar to the one use by the ``-H`` option: the disk template name
+must be specified first, followed by a colon and by a comma-separated
+list of key-value pairs. These parameters can only be specified at
+cluster and node group level; the cluster-level parameter are inherited
+by the node group at the moment of its creation, and can be further
+modified at node group level using the **gnt-group**(8) command.
+
+List of disk parameters available for the **drbd** template:
+
+resync-rate
+ Re-synchronization rate, expressed in KiB/s
+
+data-stripes
+ Number of stripes to use for data LVs
+
+meta-stripes
+ Number of stripes to use for meta LVs
+
+disk-barriers
+ What kind of barriers to **disable** for disks. It can either assume
+ the value "n", meaning no barrier disabled, or a non-empty string
+ containing a subset of the characters "bfd". "b" means disable disk
+ barriers, "f" means disable disk flushes, "d" disables disk drains
+
+meta-barriers
+ Boolean value indicating whether the meta barriers should be
+ disabled (True) or not (False).
+
+metavg
+ String containing the name of the default LVM volume group for DRBD
+ metadata. By default, it is set to ``xenvg``. It can be overridden
+ during the instance creation process by using the ``metavg`` key of
+ the ``--disk`` parameter.
+
+disk-custom
+ String containing additional parameters to be appended to the
+ arguments list of ``drbdsetup disk``.
+
+net-custom
+ String containing additional parameters to be appended to the
+ arguments list of ``drbdsetup net``.
+
+List of parameters available for the **plain** template:
+
+stripes
+ Number of stripes to use for new LVs
+
The option ``--maintain-node-health`` allows one to enable/disable
automatic maintenance actions on nodes. Currently these include
automatic shutdown of instances and deactivation of DRBD devices on
offline nodes; in the future it might be extended to automatic
-removal of unknown LVM volumes, etc.
+removal of unknown LVM volumes, etc. Note that this option is only
+useful if the use of ``ganeti-confd`` was enabled at compilation.
The ``--uid-pool`` option initializes the user-id pool. The
