 OpenStack Nova provides a cloud computing fabric controller, supporting a wide
 variety of virtualization technologies, including KVM, Xen, LXC, VMware, and

+Custom Scheduler filters
+------------------------
 
-To learn how to deploy OpenStack Salt, consult the documentation available
-online at:
+If you have a custom filter, that needs to be included in the scheduler, then you can include it like so:
 
-    https://wiki.openstack.org/wiki/OpenStackSalt
+.. code-block:: yaml
 
-In the unfortunate event that bugs are discovered, they should be reported to
-the appropriate bug tracker. If you obtained the software from a 3rd party
-operating system vendor, it is often wise to use their own bug tracker for
-reporting problems. In all other cases use the master OpenStack bug tracker,
-available at:
+  nova:
+    controller:
+      scheduler_custom_filters:
+      - my_custom_driver.nova.scheduler.filters.my_custom_filter.MyCustomFilter
 
-    http://bugs.launchpad.net/openstack-salt
+      # Then add your custom filter on the end (make sure to include all other ones that you need as well)
+      scheduler_default_filters: "DifferentHostFilter,RetryFilter,AvailabilityZoneFilter,RamFilter,CoreFilter,DiskFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,PciPassthroughFilter,MyCustomFilter"
 
-Developers wishing to work on the OpenStack Salt project should always base
-their work on the latest formulas code, available from the master GIT
-repository at:
+Hardware Trip/Unmap Support
+---------------------------
 
-    https://git.openstack.org/cgit/openstack/salt-formula-nova
+To enable TRIM support for ephemeral images (thru nova managed images), libvirt has this option.
 
-Developers should also join the discussion on the IRC list, at:

+  nova:
+    compute:
+      libvirt:
+        hw_disk_discard: unmap
+
+In order to actually utilize this feature, the following metadata must be set on the image as well, so the SCSI unmap is supported.

+
+  glance image-update --property hw_scsi_model=virtio-scsi <image>

+#    x:+name
+#      where name is a string which is matched against source file name,
+#      e.g., "remote", "qemu", or "util/json", the optional "+" prefix
+#      tells libvirt to log stack trace for each message matching name,

+#    1: DEBUG
+#    2: INFO
+#    3: WARNING
+#    4: ERROR
+#
+# Multiple filter can be defined in a single @filters, they just need to be
+# separated by spaces.
+#
+# e.g. to only get warning or errors from the remote layer and only errors
+# from the event layer:
+#log_filters="3:remote 4:event"
+
+# Logging outputs:
+# An output is one of the places to save logging information
+# The format for an output can be:
+#    x:stderr
+#      output goes to stderr
+#    x:syslog:name
+#      use syslog for the output and use the given name as the ident
+#    x:file:file_path

+#    3: WARNING
+#    4: ERROR

+# Multiple output can be defined, they just need to be separated by spaces.

+# any response before the connection is considered broken.  In other
+# words, the connection is automatically closed approximately after
+# keepalive_interval * (keepalive_count + 1) seconds since the last
+# message received from the client.  If keepalive_interval is set to
+# -1, libvirtd will never send keepalive requests; however clients
+# can still send them and the deamon will send responses.  When

+
+#
+# From nova.conf
+#
+
+#
+# When using metrics to weight the suitability of a host, you can use this
+# option
+# to change how the calculated weight influences the weight assigned to a host
+# as
+# follows:
+#
+# * >1.0: increases the effect of the metric on overall weight
+# * 1.0: no change to the calculated weight
+# * >0.0,<1.0: reduces the effect of the metric on overall weight
+# * 0.0: the metric value is ignored, and the value of the
+#   'weight_of_unavailable' option is returned instead
+# * >-1.0,<0.0: the effect is reduced and reversed
+# * -1.0: the effect is reversed
+# * <-1.0: the effect is increased proportionally and reversed
+#
+# This option is only used by the FilterScheduler and its subclasses; if you use
+# a different scheduler, this option has no effect.

+# of the metric to be weighed, and 'ratio' is the relative weight for that
+# metric.
+#
+# Note that if the ratio is set to 0, the metric value is ignored, and instead
+# the weight will be set to the value of the 'weight_of_unavailable' option.
+#
+# As an example, let's consider the case where this option is set to:
+#
+#     ``name1=1.0, name2=-1.3``
+#
+# The final weight will be:

+# Configuration options for metrics

+# Options under this group allow to adjust how values assigned to metrics are
+# calculated.
+
+#
+# From nova.conf
+#
+
+#
+# When using metrics to weight the suitability of a host, you can use this
+# option
+# to change how the calculated weight influences the weight assigned to a host
+# as
+# follows:
+#
+# * >1.0: increases the effect of the metric on overall weight
+# * 1.0: no change to the calculated weight
+# * >0.0,<1.0: reduces the effect of the metric on overall weight
+# * 0.0: the metric value is ignored, and the value of the
+#   'weight_of_unavailable' option is returned instead
+# * >-1.0,<0.0: the effect is reduced and reversed
+# * -1.0: the effect is reversed
+# * <-1.0: the effect is increased proportionally and reversed
+#
+# This option is only used by the FilterScheduler and its subclasses; if you use
+# a different scheduler, this option has no effect.
+#
+# Possible values:
+#
+# * An integer or float value, where the value corresponds to the multipler
+#   ratio for this weigher.
+#
+# Related options:
+#
+# * weight_of_unavailable
+#  (floating point value)
+#weight_multiplier=1.0
+
+#
+# This setting specifies the metrics to be weighed and the relative ratios for
+# each metric. This should be a single string value, consisting of a series of
+# one or more 'name=ratio' pairs, separated by commas, where 'name' is the name
+# of the metric to be weighed, and 'ratio' is the relative weight for that
+# metric.
+#
+# Note that if the ratio is set to 0, the metric value is ignored, and instead
+# the weight will be set to the value of the 'weight_of_unavailable' option.
+#
+# As an example, let's consider the case where this option is set to:
+#
+#     ``name1=1.0, name2=-1.3``
+#
+# The final weight will be:
+#
+#     ``(name1.value * 1.0) + (name2.value * -1.3)``
+#
+# This option is only used by the FilterScheduler and its subclasses; if you use
+# a different scheduler, this option has no effect.
+#
+# Possible values:
+#
+# * A list of zero or more key/value pairs separated by commas, where the key is
+#   a string representing the name of a metric and the value is a numeric weight
+#   for that metric. If any value is set to 0, the value is ignored and the

+#
+# This option is only used by the FilterScheduler and its subclasses; if you use

+# Keepalive protocol:
+# This allows qemu driver to detect broken connections to remote
+# libvirtd during peer-to-peer migration.  A keepalive message is
+# sent to the daemon after keepalive_interval seconds of inactivity
+# to check if the daemon is still responding; keepalive_count is a
+# maximum number of keepalive messages that are allowed to be sent
+# to the daemon without getting any response before the connection
+# is considered broken.  In other words, the connection is
+# automatically closed approximately after
+# keepalive_interval * (keepalive_count + 1) seconds since the last
+# message received from the daemon.  If keepalive_interval is set to
+# -1, qemu driver will not send keepalive requests during
+# peer-to-peer migration; however, the remote libvirtd can still
+# send them and source libvirtd will send responses.  When
+# keepalive_count is set to 0, connections will be automatically
