Hi, The fact is if you follow instruction from install.linux you manually start the kernel module and the deamon and everything works, but it doesnt install the module to be loaded at boot nor the init.d scripts.
>From my humble point of vue, as a newbye in linux and OVS it is a big lack in the installation instructions. (and the <http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=INST ALL.Linux;hb=HEAD> Building and Installing Open vSwitch link in the documentation page is broken 404) Im still looking for a /etc/init.d script to start the ovsdb server for Debian Please correct me if Im wrong, but it seems that after havin follow instruction in install.linux we still have to : - Install the modules : o Copy the openvswitch_mod.ko or openvswitch.ko from ./datapath/linux to /lib/modules/<kernel version folder/ o Run depmod o Add the module name (without .ko) to the /etc/modules file - Set the init script for ovsdb in the /etc/init.d folder o => Im still looking for this script - Set the init script for the openvswitch daemon in the /etc/init.d folder o The script is located in ./<linux distribution> folder (for RedHat I guess its ./rhel/etc_init.d_openvswitch and for debian ./debian/openvswitch-switch.init) (Also the names are not uniform among distributions ) Am I correct ? If you have some clue about a init.d script for the ovsdb daemon it would be greatly appreciated.
