Hi I am trying to decode the core dump, however, I am not familiar with the command to run the debug, can you please provide the steps?
the linux version is CentOS7 (3.10.0-514.el7.x86_64), and we currently try to run the OVS+DPDK as a VMware guest. the expected topology would be connect another two nodes with this OVS+DPDK vm.
