Hi,

We run pacemaker+corosync cluster on OpenSuSE 13.1 QEMU guests. Nodes use
OpenVSwitch bridge interface for communication.

Frequently, one node gets disconnected from cib. This is the message seen
in corosync logs,

Nov 25 08:36:07 [3760] sysmon-secondary        cib:    debug:
qb_ipcs_dispatch_connection_request:      HUP conn (3760-5529-13)
Nov 25 08:36:07 [3760] sysmon-secondary        cib:    debug:
qb_ipcs_disconnect:       qb_ipcs_disconnect(3760-5529-13) state:2
Nov 25 08:36:07 [3760] sysmon-secondary        cib:     info:
crm_client_destroy:       Destroying 0 events
Nov 25 08:36:07 [3760] sysmon-secondary        cib:    debug:
qb_rb_close:      Free'ing ringbuffer:
/dev/shm/qb-cib_ro-response-3760-5529-13-header
Nov 25 08:36:07 [3760] sysmon-secondary        cib:    debug:
qb_rb_close:      Free'ing ringbuffer:
/dev/shm/qb-cib_ro-event-3760-5529-13-header
Nov 25 08:36:07 [3760] sysmon-secondary        cib:    debug:
qb_rb_close:      Free'ing ringbuffer:
/dev/shm/qb-cib_ro-request-3760-5529-13-header

We also have corosync+pacemaker on OpenSuSE 13.1 dedicated servers and we
didn't face any problems there.

There should be some settings in openvswitch to run corosync+pacemaker
cluster.

Can you pls help fix the issue?
