Subject: xenserver: Restart ovs-xapi-sync on kmod reload.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f40af195a5b399a6a6cd8d6e91f0c7c2b6e3efc6;p=openvswitch

xenserver: Restart ovs-xapi-sync on kmod reload.

Some users never restart OVS, they just reload the kernel module on
each new version. Since ovs-xapi-sync is a daemon, a restart is
required to use the new code.  Therefore, without this patch, users
could unwittingly use stale versions of ovs-xapi-sync.

Bug #9919.
