Parameter details

-----------------

Some parameters are not straight forward, so we describe them in details

here.

.. _rapi-ipolicy:

``ipolicy``

+++++++++++

The instance policy specification is a dict with the following fields:

.. pyassert::

  constants.IPOLICY_ALL_KEYS == set([constants.ISPECS_MIN,

                                     constants.ISPECS_MAX,

                                     constants.ISPECS_STD,

                                     constants.IPOLICY_DTS,

                                     constants.IPOLICY_VCPU_RATIO])

.. pyassert::

  (set(constants.ISPECS_PARAMETER_TYPES.keys()) ==

   set([constants.ISPEC_MEM_SIZE,

        constants.ISPEC_DISK_SIZE,

        constants.ISPEC_DISK_COUNT,

        constants.ISPEC_CPU_COUNT,

        constants.ISPEC_NIC_COUNT]))

.. |ispec-min| replace:: :pyeval:`constants.ISPECS_MIN`

.. |ispec-max| replace:: :pyeval:`constants.ISPECS_MAX`

.. |ispec-std| replace:: :pyeval:`constants.ISPECS_STD`

|ispec-min|, |ispec-max|, |ispec-std|

  A sub- `dict` with the following fields, which sets the limit and standard

  values of the instances:

  :pyeval:`constants.ISPEC_MEM_SIZE`

    The size in MiB of the memory used

  :pyeval:`constants.ISPEC_DISK_SIZE`

    The size in MiB of the disk used

  :pyeval:`constants.ISPEC_DISK_COUNT`

    The numbers of disks used

  :pyeval:`constants.ISPEC_CPU_COUNT`

    The numbers of cpus used

  :pyeval:`constants.ISPEC_NIC_COUNT`

    The numbers of nics used

:pyeval:`constants.IPOLICY_DTS`

  A `list` of disk templates allowed for instances using this policy

:pyeval:`constants.IPOLICY_VCPU_RATIO`

  Maximum ratio of virtual to physical CPUs (`float`)

     "Cluster-wide :ref:`instance policy <rapi-ipolicy>` specs"),

    ("ipolicy", None, ht.TMaybeDict,
