Hi everyone,
I'm using Openstack Train and Openvswitch for ML2 driver and GRE for tunnel type. I tested our network performance between two VMs and suffer packet loss as below.
VM1: IP: 10.20.1.206
VM2: IP: 10.20.1.154
VM3: IP: 10.20.1.72
Using iperf3 to testing performance between VM1 and VM2.
Run iperf3 client and server on both VMs.
On VM2: iperf3 -t 10000 -b 130M -l 442 -P 6 -u -c 10.20.1.206
On VM1: iperf3 -t 10000 -b 130M -l 442 -P 6 -u -c 10.20.1.154
Using VM3 ping into VM1, then the packet is lost and the latency is quite high.
ping -i 0.1 10.20.1.206

Does any one get this issue ?
Please help me. Thanks
