Subject: xenserver: Restart HA daemon after force-reload-kmod.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c002dde70329b5553b79f3f1ad6d60771f4179c0;p=openvswitch

xenserver: Restart HA daemon after force-reload-kmod.

Otherwise its heartbeats start failing after the reload and the XenServer
reboots after a minute or so.

Thanks to Justin Pettit for figuring out that this was HA-related.

Bug #5706.
