fedora package: fix systemd ordering and deps. There is a chicken and egg issue where common OVS configuration uses a controller which is only accessible via the network. So starting OVS before network.target would break those configurations. However, the network doesn't come up after boot because OVS isn't started until after the network scripts tries to configure the ovs. This is partially fixed by commits: commit: 602453000e28ec1076c0482ce13c284765a84409 rhel: Automatically start openvswitch service before bringing an ovs interfa commit: 3214851c31538e8690e31f95702f8927a8c0838b rhel: Add OVSREQUIRES to automatically bring up OpenFlow interface dependencies But still there is the dependency issue between network.target and openvswitch which this patch fixes it. It provides two systemd service units. One to run at any time (openvswitch-nonetwork.service) which runs 'ovs-ctl start' and the other one (openvswith.service) to run after network.target which works as a frontend to the admin. The openvswitch-nonetwork.service is used internally by the 'ifup-ovs/ifdown-ovs' scripts when adding or removing ports to the bridge or when the openvswitch.service is enabled by the admin.

rhel: Improved Systemd Integration This commit builds upon some of the recent ovs-ctl changes to build a more integrated systemd setup. A new service (ovs-vswitchd) is added to track the ovs-vswitchd, and ovsdb-server service is reserved for the ovsdb-server daemon. The systemd scripts still use ovs-ctl to actually initialize the daemons.

Description=Open vSwitch Database Unit
rhel-systemd: Delay shutting down the services During testing it was found that systemd would consider the openvswitch service as a part of networking component, but the dependent services of ovs-vswitchd and ovsdb-server were not likewise considered. This leads to some strange race conditions, observed when using NFS over TCP, while shutting down systems.

rhel-systemd: Restart openvswitch service if a daemon crashes Currently if either ovsdb-server or ovs-vswitchd is crashing the daemon is not restarting leaving the system in faulty state. This patch will detect the daemon crash and will restart the openvswitch service. Here is a (bit to wide) table showing the behavior before and after the patch.

redhat: allow arbitrary user:group Under rpm based distributions, the only user:group that the rhel daemons run as is 'root:root'. This is fine as a default, but as part of a security procedure, users may want to run as an alternate uid/gid. This commit adds an OVS_USER_ID environment variable for systemd, which defaults to root:root, but can be overridden by changing the /etc/sysconfig/openvswitch environment file.
