Hypervisor State Parameters

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Using ``--hypervisor-state`` you can set hypervisor specific states as

pointed out in ``Ganeti Resource Model <design-resource-model.rst>``.

The format is: ``hypervisor:option=value``.

Currently we support the following hypervisor state values:

mem_total

  Total node memory, as discovered by this hypervisor

mem_node

  Memory used by, or reserved for, the node itself; note that some

  hypervisors can report this in an authoritative way, other not

mem_hv

  Memory used either by the hypervisor itself or lost due to instance

  allocation rounding; usually this cannot be precisely computed, but

  only roughly estimated

cpu_total

  Total node cpu (core) count; usually this can be discovered

  automatically

cpu_node

  Number of cores reserved for the node itself; this can either be

  discovered or set manually. Only used for estimating how many VCPUs

  are left for instances

Disk State Parameters

~~~~~~~~~~~~~~~~~~~~~

Using ``--disk-state`` you can set disk specific states as pointed out

in ``Ganeti Resource Model <design-resource-model.rst>``.

The format is: ``storage_type/identifier:option=value``. Where we

currently just support ``lvm`` as storage type. The identifier in this

case is the LVM volume group. By default this is ``xenvg``.

Currently we support the following hypervisor state values:

disk_total

  Total disk size (usually discovered automatically)

disk_reserved

  Reserved disk size; this is a lower limit on the free space, if such a

  limit is desired

disk_overhead

  Disk that is expected to be used by other volumes (set via

  ``reserved_lvs``); usually should be zero
