+during boot. The following commands can be used:
+ % bcdedit /set LOADOPTIONS DISABLE_INTEGRITY_CHECKS
+ % bcdedit /set TESTSIGNING ON
+ % bcdedit /set nointegritychecks ON
+
+Note: you may have to restart the machine for the settings to take effect.
+
+03> In the Virtual Switch Manager configuration you can enable the Open vSwitch
+Extension on an existing switch or create a new switch. If you are using an
+existing switch, make sure to enable the "Allow Management OS" option for VXLAN
+to work (covered later).
+
+The command to create a new switch named 'OVS-Extended-Switch' using a physical
+NIC named 'Ethernet 1' is:
+ % New-VMSwitch "OVS-Extended-Switch" -AllowManagementOS $true \
+ -NetAdapterName "Ethernet 1"
+
+Note: you can obtain the list of physical NICs on the host using
+'Get-NetAdapter' command.
+
+04> In the properties of any switch, you should should now see "Open
+vSwitch Extension" under 'Extensions'. Click the check box to enable the
+extension. An alternative way to do the same is to run the following command:
+ % Enable-VMSwitchExtension "Open vSwitch Extension" OVS-Extended-Switch
+
+Note: If you enabled the extension using the command line, a delay of a few
+seconds has been observed for the change to be reflected in the UI. This is
+not a bug in Open vSwitch.
+
+Steps to run the user processes & configure ports
+-------------------------------------------------
+The following steps assume that you have installed the Open vSwitch
+utilities in the local machine via 'make install'.
+
+01> Create the database.
+ % ovsdb-tool create C:\openvswitch\etc\openvswitch\conf.db \
+ C:\openvswitch\usr\share\openvswitch\vswitch.ovsschema
+
+02> Start the ovsdb-server and initialize the database.
+ % ovsdb-server -vfile:info --remote=punix:db.sock --log-file --pidfile \
+ --detach
+ % ovs-vsctl --no-wait init
+
+ If you would like to terminate the started ovsdb-server, run:
+ % ovs-appctl -t ovsdb-server exit
+
+ (Note that the logfile is created at C:/openvswitch/var/log/openvswitch/)
+
+03> Start ovs-vswitchd.
+ % ovs-vswitchd -vfile:info --log-file --pidfile --detach
+
+ If you would like to terminate the started ovs-vswitchd, run:
+ % ovs-appctl exit
+
+ (Note that the logfile is created at C:/openvswitch/var/log/openvswitch/)
+
+04> Create integration bridge & pif bridge
+ % ovs-vsctl add-br br-int
+ % ovs-vsctl add-br br-pif
+
+NOTE: There's a known bug that running the ovs-vsctl command does not
+terminate. This is generally solved by having ovs-vswitchd running. If
+you face the issue despite that, hit Ctrl-C to terminate ovs-vsctl and
+check the output to see if your command succeeded.
+
+NOTE: There's a known bug that the ports added to OVSDB via ovs-vsctl don't
+get to the kernel datapath immediately, ie. they don't show up in the output of
+"ovs-dpctl show" even though they show up in output of "ovs-vsctl show".
+In order to workaround this issue, restart ovs-vswitchd. (You can terminate
+ovs-vswitchd by running 'ovs-appctl exit'.)
+
+05> Dump the ports in the kernel datapath
+ % ovs-dpctl show
+
+* Sample output is as follows:
+
+ % ovs-dpctl show
+ system@ovs-system:
+ lookups: hit:0 missed:0 lost:0
+ flows: 0
+ port 2: br-pif (internal) <<< internal port on 'br-pif' bridge
+ port 1: br-int (internal) <<< internal port on 'br-int' bridge
+
+06> Dump the ports in the OVSDB
+ % ovs-vsctl show
+
+* Sample output is as follows:
+ % ovs-vsctl show
+ a56ec7b5-5b1f-49ec-a795-79f6eb63228b
+ Bridge br-pif
+ Port br-pif
+ Interface br-pif
+ type: internal
+ Bridge br-int
+ Port br-int
+ Interface br-int
+ type: internal
+
+07> Add the physical NIC and the internal port to br-pif.
+
+In OVS for Hyper-V, we use the name of the adapter on top of which the Hyper-V
+virtual switch was created, as a special name to refer to the physical NICs
+connected to the Hyper-V switch. I.e. let us suppose we created the Hyper-V
+virtual switch on top of the adapter named 'Ethernet0'. In OVS for Hyper-V, we
+use that name('Ethernet0') as a special name to refer to that adapter.
+
+Note: Currently, we assume that the Hyper-V switch on which OVS extension is
+enabled has a single physical NIC connected to it.
+
+Internal port is the virtual adapter created on the Hyper-V switch using the
+'AllowManagementOS' setting. This has already been setup while creating the
+switch using the instructions above. In OVS for Hyper-V, we use a the name of
+that specific adapter as a special name to refer to that adapter. By default it
+is created under the following rule "vEthernet (<name of the switch>)".
+
+As a whole example, if we issue the following in a powershell console:
+PS C:\package\binaries> Get-NetAdapter | select Name,MacAddress,InterfaceDescription
+
+Name MacAddress InterfaceDescription
+---- ---------- --------------------
+Ethernet1 00-0C-29-94-05-65 Intel(R) PRO/1000 MT Network Connection
+vEthernet (external) 00-0C-29-94-05-5B Hyper-V Virtual Ethernet Adapter #2
+Ethernet0 00-0C-29-94-05-5B Intel(R) PRO/1000 MT Network Connection #2
+
+PS C:\package\binaries> Get-VMSwitch
+
+Name SwitchType NetAdapterInterfaceDescription
+---- ---------- ------------------------------
+external External Intel(R) PRO/1000 MT Network Connection #2
+
+
+We can see that we have a switch(external) created upon adapter name 'Ethernet0'
+with an internal port under name 'vEthernet (external)'. Thus resulting into the
+following ovs-vsctl commands
+
+ % ovs-vsctl add-port br-pif Ethernet0
+ % ovs-vsctl add-port br-pif "vEthernet (external)"
+
+* Dumping the ports should show the additional ports that were just added.
+ Sample output shows up as follows:
+
+ % ovs-dpctl show
+ system@ovs-system:
+ lookups: hit:0 missed:0 lost:0
+ flows: 0
+ port 4: vEthernet (external) (internal) <<< 'AllowManagementOS'
+ adapter on
+ Hyper-V switch
+ port 2: br-pif (internal)
+ port 1: br-int (internal)
+ port 3: Ethernet0 <<< Physical NIC
+
+ % ovs-vsctl show
+ a56ec7b5-5b1f-49ec-a795-79f6eb63228b
+ Bridge br-pif
+ Port "vEthernet (external)"
+ Interface "vEthernet (external)"
+ Port br-pif
+ Interface br-pif
+ type: internal
+ Port "Ethernet0"
+ Interface "Ethernet0"
+ Bridge br-int
+ Port br-int
+ Interface br-int
+ type: internal
+
+08> Add the VIFs to br-int
+
+Adding VIFs to openvswitch is a two step procedure. The first step is to
+assign a 'OVS port name' which is a unique name across all VIFs on this
+Hyper-V. The next step is to add the VIF to the ovsdb using its 'OVS port
+name' as key.
+
+08a> Assign a unique 'OVS port name' to the VIF
+
+Note that the VIF needs to have been disconnected from the Hyper-V switch
+before assigning a 'OVS port name' to it. In the example below, we assign a
+'OVS port name' called 'ovs-port-a' to a VIF on a VM by name 'VM1'. By using
+index 0 for '$vnic', the first VIF of the VM is being addressed. After
+assigning the name 'ovs-port-a', the VIF is connected back to the Hyper-V
+switch with name 'OVS-HV-Switch', which is assumed to be the Hyper-V switch
+with OVS extension enabled.
+
+ Eg:
+ % import-module .\datapath-windows\misc\OVS.psm1
+ % $vnic = Get-VMNetworkAdapter <Name of the VM>
+ % Disconnect-VMNetworkAdapter -VMNetworkAdapter $vnic[0]
+ % $vnic[0] | Set-VMNetworkAdapterOVSPort -OVSPortName ovs-port-a
+ % Connect-VMNetworkAdapter -VMNetworkAdapter $vnic[0] \
+ -SwitchName OVS-Extended-Switch
+
+08b> Add the VIFs to br-int in ovsdb
+
+ Eg:
+ % ovs-vsctl add-port br-int ovs-port-a
+
+09> Verify the status
+ % ovs-dpctl show
+ system@ovs-system:
+ lookups: hit:0 missed:0 lost:0

+
+ % ovs-vsctl show
+ 4cd86499-74df-48bd-a64d-8d115b12a9f2

+
+Steps to configure patch ports and switch VLAN tagging
+------------------------------------------------------
+The Windows Open vSwitch implementation support VLAN tagging in the switch.
+Switch VLAN tagging along with patch ports between 'br-int' and 'br-pif' is
+used to configure VLAN tagging functionality between two VMs on different
+Hyper-Vs. The following examples demonstrate how it can be done:
+
+01> Add a patch port from br-int to br-pif
+ % ovs-vsctl add-port br-int patch-to-pif
+ % ovs-vsctl set interface patch-to-pif type=patch \
+ options:peer=patch-to-int
+
+02> Add a patch port from br-pif to br-int
+ % ovs-vsctl add-port br-pif patch-to-int
+ % ovs-vsctl set interface patch-to-int type=patch \
+ options:peer=patch-to-pif
+
+03> Re-Add the VIF ports with the VLAN tag
+ % ovs-vsctl add-port br-int ovs-port-a tag=900
+ % ovs-vsctl add-port br-int ovs-port-b tag=900
+
+Steps to add tunnels
+--------------------------
+The Windows Open vSwitch implementation support VXLAN and STT tunnels. To add
+tunnels, the following steps serve as examples.
+
+Note that, any patch ports created between br-int and br-pif MUST be beleted
+prior to adding tunnels.
+
+01> Add the tunnel port between 172.168.201.101 <-> 172.168.201.102
+ % ovs-vsctl add-port br-int tun-1
+ % ovs-vsctl set Interface tun-1 type=port-type
+ % ovs-vsctl set Interface tun-1 options:local_ip=172.168.201.101
+ % ovs-vsctl set Interface tun-1 options:remote_ip=172.168.201.102
+ % ovs-vsctl set Interface tun-1 options:in_key=flow
+ % ovs-vsctl set Interface tun-1 options:out_key=flow
+
+02> Add the tunnel port between 172.168.201.101 <-> 172.168.201.105
+ % ovs-vsctl add-port br-int tun-2
+ % ovs-vsctl set Interface tun-2 type=port-type
+ % ovs-vsctl set Interface tun-2 options:local_ip=172.168.201.102
+ % ovs-vsctl set Interface tun-2 options:remote_ip=172.168.201.105
+ % ovs-vsctl set Interface tun-2 options:in_key=flow
+ % ovs-vsctl set Interface tun-2 options:out_key=flow
+
+ Where port-type is the string stt or vxlan
