<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">Are you running with containerized OVS (system vswitch_type=none) or OVS-DPDK on the host (system vswitch_type=ovs-dpdk)?<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">In either case, I would examine the logs from OVS to see if there are any errors being generated for the host that is exhibiting the failure.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">In addition, you can check your infrastructure data network configuration to ensure it is setup as you expected by reviewing the LLDP information for the host (system host-lldp-neighbor-list) or the graphical display on the dashboard.<o:p></o:p></p>

detail, in most times over night) the data-network from all VMs are broken down, no connection over data-network are available any more. the other worker is running fine without any problems. if i live migrate the VMs from one to another worker and back again,
the data-network is comming up and all is fine again. i do not find any logs that will explain this problem, any suggestions or hints for locking for?</span><o:p></o:p></p>
