commit 71edbb0d7de06458bb1be345e13841ad4e7c2bb9 Author: Huan Xie <[email protected]> Date: Wed Dec 7 02:13:19 2016 +0000 Support ovsdb-client monitor with remote connection When using XenServer as hypervisor, we found we cannot set ovs agent which runs in compute node with "minimize_polling=True". Because once set it True, the ovs agent will monitor the local ovsdb, but we want it monitor ovsdb in Dom0. This patch is to add support for ovsdb-client to monitor remote connection.
