[ovs-discuss] changing path for startup

[Rajasekaran, Monica]

Thanks Ben!

Do you know what might cause this message ? Type 16 is for statistics right ?

2016-06-23T00:41:55Z|00025|ofp_msgs|WARN|unknown OpenFlow message (version 1, type 16, stat 12)

It happens after my OVS is connected to the controller. Also sends out a bad response after this.

Thanks,
Monica

INSTALL.md says:

    By default all files are installed under /usr/local.  Open vSwitch also
    expects to find its database in /usr/local/etc/openvswitch by default.
    If you want to install all files into, e.g., /usr and /var instead of
    /usr/local and /usr/local/var and expect to use /etc/openvswitch as the default
    database directory, add options as shown here:

          `% ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc`
