Hi, everyone:
一. after i change ovn/ovn-[sn]b.ovsschema, how to apply the changes?
makefile compiles ovn/ovn-[sn]b.ovsschema to
ovn/lib/ovn-[s,n]b-idl.ovsidl, i can not find anyone use
ovn-[s,n]b-idl.ovsidl.
As the name suggests, *.ovsschema defines schema only. You still need to
write code which uses your new tables. It should be possible to fill
them with ovs-vsctl, but without something reading them, this would be
dead data.
二. lets take sb for example.
ovsdb-server --detach --monitor -vconsole:off
--log-file=/var/log/openvswitch/ovsdb-server-sb.log
--remote=punix:/run/openvswitch/ovnsb_db.sock
--pidfile=/run/openvswitch/ovnsb_db.pid
--remote=db:OVN_Southbound,SB_Global,connections --unixctl=ovnsb_db.ctl
--private-key=db:OVN_Southbound,SSL,private_key
--certificate=db:OVN_Southbound,SSL,certificate
--ca-cert=db:OVN_Southbound,SSL,ca_cert /var/lib/openvswitch/ovnsb_db.db
1. who launches the ovsdb-server process? and when?
Usually this happens from the init scripts. The real machinery is under
${PREFIX}/share/openvswitch/scripts.
2. how /var/lib/openvswitch/ovnsb_db.db is created？
You can use ovsdb-tool create, see INSTALL.md. ovn-ctl script called
from init scripts should handle this automatically.
3. 'ovn-sbctl set-connection ptp:6642' how this instruction
associates port 6642 with ovsdb-server (please tell the source code)
三. supported the new db is created, whether or not i need to code c
funtion like sbrec_idl_class in ovn/lib/ovn-sb-idl.c
This is basically a compiled schema definition. You should start at
ovn/utilities/ovn-sbctl.c
too many questions, please help me figure it out.
thanks very much
Just don't forget to consult the documentation, some of your questions
are already answered there ;-)

Hi,
Look at ovn/ovn-[sn]b.ovsschema. It's JSON. You'll also need to update
the documentation and the cksum; make explains how to do it.
Best,
Valentine
