When using file-backed memory, the ``nova-compute`` service will now fail
|
|
to start if the amount of reserved memory configured using ``[DEFAULT]
|
|
reserved_host_memory_mb`` is equal to or greater than the total amount of
|
|
memory configured using ``[libvirt] file_backed_memory``. Where reserved
|
|
memory is less than the total amount of memory configured, a warning will
|
|
be raised. This warning will become an error in a future release.
|
|
|
|
The former combination is invalid as it would suggest reserved memory is
|
|
greater than total memory available, while the latter is considered
|
|
incorrect behavior as reserving of file-backed memory can and should be
|
|
achieved by reducing the filespace allocated as memory by modifying
|
|
``[libvirt] file_backed_memory``.
