Cross posting to dpdk-dev. What kernel version are you running in the guest? there was previously an issue with the DPDK vhost-library and 3.19 I think. It might be worth to test OVS head of master with DPDK 2.1, or DPDK 2.2-rc3. > > We try QEMU 2.3.1, QEMU 2.2.1 and QEMU 2.1.3 on host8, but no effect. > Now we use DPDK2.0, OVS2.4. > > [root at host8 ~]# coredumpctl gdb 5295 > ???????????PID: 5295 (ovs-vswitchd) > ??????????
