Thu Oct 10 10:45:32 UTC 2019
Adding a wrapper to ovs-sim called ovn-sim, which re-introduces the
primitives for OVN in the simulator that were lost as part of
the ovn-org/ovn split.
Also resurrected the man page used to document ovn-sim usage.
Lastly, there were some leftover ovs-sim references that were
not proper. This patch renames these to ovn-sim.
All in all, this change is nothing but porting over the
OVN sections of ovs-sim from OVS version 2.12 (pre-split).

+Synopsis

+
+``ovn-sim`` [*option*]... [*script*]...
+
+Description
+===========
+
+``ovn-sim`` is a wrapper script that adds ovn related commands on
+top of ``ovs-sim``.
+
+``ovs-sim`` provides a convenient environment for running one or more Open
+vSwitch instances and related software in a sandboxed simulation environment.
+
+To use ``ovn-sim``, first build Open vSwitch, then invoke it directly from the
+build directory, e.g.::
+
+ git clone https://github.com/openvswitch/ovs.git
+ cd ovs
+ ./boot.sh && ./configure && make
+ cd ..
+ git clone https://github.com/ovn-org/ovn.git
+ cd ovn
+ ./boot.sh && ./configure --with-ovs-source=${PWD}/../ovs
+ make
+ utilities/ovn-sim
+
+See documentation on ``ovs-sim`` for info on simulator, including the
+parameters you can use.
+
+OVN Commands
+------------
+
+These commands interact with OVN, the Open Virtual Network.
+
+``ovn_start`` [*options*]
+ Creates and initializes the central OVN databases (both
+ ``ovn-sb(5)`` and ``ovn-nb(5)``) and starts an instance of
+ ``ovsdb-server`` for each one. Also starts an instance of
+ ``ovn-northd``.
+
+ The following options are available:
+
+ ``--nbdb-model`` *model*
+ Uses the given database model for the northbound database.
+ The *model* may be ``standalone`` (the default), ``backup``,
+ or ``clustered``.
+
+ ``--nbdb-servers`` *n*
+ For a clustered northbound database, the number of servers in
+ the cluster. The default is 3.
+
+ ``--sbdb-model`` *model*
+ Uses the given database model for the southbound database.
+ The *model* may be ``standalone`` (the default), ``backup``,
+ or ``clustered``.
+
+ ``--sbdb-servers`` *n*
+ For a clustered southbound database, the number of servers in
+ the cluster. The default is 3.
+
+``ovn_attach`` *network* *bridge* *ip* [*masklen*]
+ First, this command attaches bridge to interconnection network
+ network, just like ``net_attach`` *network* *bridge*. Second, it
+ configures (simulated) IP address *ip* (with network mask length
+ *masklen*, which defaults to 24) on *bridge*. Finally, it
+ configures the Open vSwitch database to work with OVN and starts
+ ``ovn-controller``.
+
+Examples
+========
+
+Simulating hypervisors, starting ovn controller (via ovn_attach) and
+adding a logical port on each one of them::
+
+ ovn_start
+ ovn-nbctl ls-add lsw0
+ net_add n1
+ for i in 0 1; do
+ sim_add hv$i
+ as hv$i
+ ovs-vsctl add-br br-phys
+ ovn_attach n1 br-phys 192.168.0.`expr $i + 1`
+ ovs-vsctl add-port br-int vif$i -- \
+ set Interface vif$i external-ids:iface-id=lp$i
+ ovn-nbctl lsp-add lsw0 lp$i
+ ovn-nbctl lsp-set-addresses lp$i f0:00:00:00:00:0$i
+ done
+
+Here’s a primitive OVN "scale test" (adjust the scale by changing
+``n`` in the first line)::
+
+ n=200; export n
+ ovn_start --sbdb-model=clustered
+ net_add n1
+ ovn-nbctl ls-add br0
+ for i in `seq $n`; do
+ (sim_add hv$i
+ as hv$i
+ ovs-vsctl add-br br-phys
+ y=$(expr $i / 256)
+ x=$(expr $i % 256)
+ ovn_attach n1 br-phys 192.168.$y.$x
+ ovs-vsctl add-port br-int vif$i -- \
+ set Interface vif$i external-ids:iface-id=lp$i) &
+ case $i in
+ *50|*00) echo $i; wait ;;
+ esac
+ done
+ wait
+ for i in `seq $n`; do
+ yy=$(printf %02x $(expr $i / 256))
+ xx=$(printf %02x $(expr $i % 256))
+ ovn-nbctl lsp-add br0 lp$i
+ ovn-nbctl lsp-set-addresses lp$i f0:00:00:00:$yy:$xx
+ done
+
+When the scale test has finished initializing, you can watch the
+logical ports come up with a command like this::
+
+ watch 'for i in `seq $n`; do \
+ if test `ovn-nbctl lsp-get-up lp$i` != up; then echo $i; fi; done'

-Synopsis
-========
-
-``ovs-sim`` [*option*]... [*script*]...
-
-Description
-===========
-
-``ovs-sim`` provides a convenient environment for running one or more Open
-vSwitch instances and related software in a sandboxed simulation environment.
-
-To use ``ovs-sim``, first build Open vSwitch, then invoke it directly from the
-build directory, e.g.::
-
- git clone https://github.com/openvswitch/ovs.git
- cd ovs
- ./configure
- make
- utilities/ovs-sim
-
-When invoked in the most ordinary way as shown above, ovs-sim does the
-following:
-
-1. Creates a directory ``sandbox`` as a subdirectory of the current
- directory (first destroying such a directory if it already exists)
- and makes it the current directory.
-
-2. Installs all of the Open vSwitch manpages into a ``man``
- subdirectory of sandbox and adjusts the ``MANPATH`` environment
- variable so that ``man`` and other manpage viewers can find them.
-
-3. Creates a simulated Open vSwitch named ``main`` and sets it up as the
- default target for OVS commands, as if the following ``ovs-sim``
- commands had been run::
-
- sim_add main
- as main
-
- See `Commands`_, below, for an explanation.
-
-4. Runs any scripts specified on the command line (see `Options`_,
- below). The scripts can use arbitrary Bash syntax, plus the
- additional commands described under `Commands`_, below.
-
-5. If no scripts were specified, or if ``-i`` or ``--interactive`` was
- specified, invokes an interactive Bash subshell. The user can use
- arbitrary Bash commands, plus the additional commands described under
- `Commands`_, below.
-
-``ovs-sim`` and the sandbox environment that it creates does not require
-superuser or other special privileges. Generally, it should not be run with
-such privileges.
-
-Options
-=======
-
-.. program: ovs-sim
-
-*script*
- Runs *script*, which should be a Bash script, within a subshell
- after initializing. If multiple script arguments are given, then
- they are run in the order given. If any script exits with a
- nonzero exit code, then ``ovs-sim`` exits immediately with the
- same exit code.
-
-``-i`` or ``--interactive``
- By default, if any script is specified, ``ovs-sim`` exits as soon as the
- scripts finish executing. With this option, or if no scripts are specified,
- ``ovs-sim`` instead starts an interactive Bash session.
-
-Commands
-========
-
-Scripts and interactive usage may use the following commands
-implemented by ``ovs-sim``. They are implemented as Bash shell functions
-exported to subshells.
-
-Basic Commands
---------------
-
-These are the basic commands for working with sandboxed Open vSwitch
-instances.
-
-``sim_add`` *sandbox*
- Starts a new simulated Open vSwitch instance named *sandbox*.
- Files related to the instance, such as logs, databases, sockets,
- and pidfiles, are created in a subdirectory also named
- *sandbox*. Afterward, the ``as`` command (see below) can be used
- to run Open vSwitch utilities in the context of the new sandbox.
-
- The new sandbox starts out without any bridges. Use ``ovs-vsctl``
- in the context of the new sandbox to create a bridge, e.g.::
-
- sim_add hv0 # Create sandbox hv0.
- as hv0 # Set hv0 as default sandbox.
- ovs-vsctl add-br br0 # Add bridge br0 inside hv0.
-
- The Open vSwitch instances that ``sim_add`` creates enable
- ``dummy`` devices. This means that bridges and interfaces can be
- created with type ``dummy`` to indicate that they should be
- totally simulated, without any reference to system entities. In
- fact, ``ovs-sim`` also configures Open vSwitch so that the default
- system type of bridges and interfaces are replaced by dummy
- devices. Other types of devices, however, retain their usual
- functions, which means that, e.g., vxlan tunnels still act as
- tunnels (refer to the documentation).
-
-``as`` *sandbox*
- Sets sandbox as the default simulation target for Open vSwitch
- commands (e.g. ``ovs-vsctl``, ``ovs-ofctl``, ``ovs-appctl``).
-
- This command updates the beginning of the shell prompt to indicate
- the new default target.
-
-``as`` *sandbox* *command* *arg*...
- Runs the given command with *sandbox* as the simulation target,
- e.g. ``as hv0 ovs-vsctl add-br br0`` runs ``ovs-vsctl add-br
- br0`` within sandbox ``hv0``. The default target is unchanged.
-
-Interconnection Network Commands
---------------------------------
-
-When multiple sandboxed Open vSwitch instances exist, one will
-inevitably want to connect them together. These commands allow for
-that. Conceptually, an interconnection network is a switch that
-``ovs-sim`` makes it easy to plug into other switches in other
-sandboxed Open vSwitch instances. Interconnection networks are
-implemented as bridges in the ``main`` switch that ``ovs-sim`` creates
-by default, so to use interconnection networks please avoid working
-with ``main`` directly.
-
-``net_add`` *network*
- Creates a new interconnection network named *network*.
-
-``net_attach`` *network* *bridge*
- Adds a new port to *bridge* in the default sandbox (as set with
- ``as``) and plugs it into interconnection network *network*, which
- must already have been created by a previous invocation of
- ``net_add``. The default sandbox must not be ``main``.
-
-OVN Commands
-------------
-
-These commands interact with OVN, the Open Virtual Network.
-
-``ovn_start`` [*options*]
- Creates and initializes the central OVN databases (both
- ``ovn-sb(5)`` and ``ovn-nb(5)``) and starts an instance of
- ``ovsdb-server`` for each one. Also starts an instance of
- ``ovn-northd``.
-
- The following options are available:
-
- ``--nbdb-model`` *model*
- Uses the given database model for the northbound database.
- The *model* may be ``standalone`` (the default), ``backup``,
- or ``clustered``.
-
- ``--nbdb-servers`` *n*
- For a clustered northbound database, the number of servers in
- the cluster. The default is 3.
-
- ``--sbdb-model`` *model*
- Uses the given database model for the southbound database.
- The *model* may be ``standalone`` (the default), ``backup``,
- or ``clustered``.
-
- ``--sbdb-servers`` *n*
- For a clustered southbound database, the number of servers in
- the cluster. The default is 3.
-
-``ovn_attach`` *network* *bridge* *ip* [*masklen*]
- First, this command attaches bridge to interconnection network
- network, just like ``net_attach`` *network* *bridge*. Second, it
- configures (simulated) IP address *ip* (with network mask length
- *masklen*, which defaults to 24) on *bridge*. Finally, it
- configures the Open vSwitch database to work with OVN and starts
- ``ovn-controller``.
-
-Examples
-========
-
-The following creates a pair of Open vSwitch instances ``hv0`` and
-``hv1``, adds a port named ``vif0`` or ``vif1``, respectively, to each
-one, and then connects the two through an interconnection network
-``n1``::
-
- net_add n1
- for i in 0 1; do
- sim_add hv$i
- as hv$i ovs-vsctl add-br br0 -- add-port br0 vif$i
- as hv$i net_attach n1 br0
- done
-
-Here’s an extended version that also starts OVN::
-
- ovn_start
- ovn-nbctl ls-add lsw0
- net_add n1
- for i in 0 1; do
- sim_add hv$i
- as hv$i
- ovs-vsctl add-br br-phys
- ovn_attach n1 br-phys 192.168.0.`expr $i + 1`
- ovs-vsctl add-port br-int vif$i -- set Interface vif$i external-ids:iface-id=lp$i
- ovn-nbctl lsp-add lsw0 lp$i
- ovn-nbctl lsp-set-addresses lp$i f0:00:00:00:00:0$i
- done
-
-Here’s a primitive OVN "scale test" (adjust the scale by changing
-``n`` in the first line::
-
- n=200; export n
- ovn_start --sbdb-model=clustered
- net_add n1
- ovn-nbctl ls-add br0
- for i in `seq $n`; do
- (sim_add hv$i
- as hv$i
- ovs-vsctl add-br br-phys
- y=$(expr $i / 256)
- x=$(expr $i % 256)
- ovn_attach n1 br-phys 192.168.$y.$x
- ovs-vsctl add-port br-int vif$i -- set Interface vif$i external-ids:iface-id=lp$i) &
- case $i in
- *50|*00) echo $i; wait ;;
- esac
- done
- wait
- for i in `seq $n`; do
- yy=$(printf %02x $(expr $i / 256))
- xx=$(printf $02x $(expr $i % 256))
- ovn-nbctl lsp-add br0 lp$i
- ovn-nbctl lsp-set-addresses lp$i f0:00:00:00:$yy:$xx
- done
-
-When the scale test has finished initializing, you can watch the
-logical ports come up with a command like this::
-
- watch 'for i in `seq $n`; do if test `ovn-nbctl lsp-get-up lp$i` != up; then echo $i; fi; done'
