Subject: [PATCH] fedora package: fix systemd ordering and deps.
|
|
|
28fc1e |
|
|
|
28fc1e |
There is a chicken and egg issue where common OVS
|
|
|
28fc1e |
configuration uses a controller which is only accessible
|
|
|
28fc1e |
via the network. So starting OVS before network.target
|
|
|
28fc1e |
would break those configurations.
|
|
|
28fc1e |
|
|
|
28fc1e |
However, the network doesn't come up after boot because
|
|
|
28fc1e |
OVS isn't started until after the network scripts tries
|
|
|
28fc1e |
to configure the ovs.
|
|
|
28fc1e |
|
|
|
28fc1e |
This is partially fixed by commits:

|
|

rhel: Automatically start openvswitch service before bringing an ovs interfa
|
|
|
28fc1e |
|
|
|
28fc1e |
commit: 3214851c31538e8690e31f95702f8927a8c0838b
|
|
|
28fc1e |
rhel: Add OVSREQUIRES to automatically bring up OpenFlow interface dependencies
|
|
|
28fc1e |
|
|
|
28fc1e |
But still there is the dependency issue between network.target
|
|
|
28fc1e |
and openvswitch which this patch fixes it. It provides two systemd
|
|
|
28fc1e |
service units. One to run at any time (openvswitch-nonetwork.service)
|
|
|
28fc1e |
which runs 'ovs-ctl start' and the other one (openvswith.service) to
|
|
|
28fc1e |
run after network.target which works as a frontend to the admin.
|
|
|
28fc1e |
|
|
|
28fc1e |
The openvswitch-nonetwork.service is used internally by the
|
|
|
28fc1e |
'ifup-ovs/ifdown-ovs' scripts when adding or removing ports to
|
|
|
28fc1e |
the bridge or when the openvswitch.service is enabled by the admin.
