<p class="MsoNormal"><span lang="EN-CA">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></span></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">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></span></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">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></span></p>

do not know in 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?<o:p></o:p></span></p>
