Hi Satish,
Did your packet loss happen always or it only happened when heavy load?
AFAIK, if you do not tun anything, the vm tap can process about 50kpps before
the tap device start to drop packets.
If it happened in heavy load, couple of things you can try:
1) increase tap queue length,
[root@compute-33 ~]# ifconfig tap5af7f525-5f | grep -i drop
RX errors 0 dropped 0 overruns 0 frame 0
TX errors 0 dropped 2528788837 overruns 0 carrier 0 collisions 0
Noticed tap interface dropping TX packets and even after increasing
txqueue from 1000 to 1 nothing changed, stil
Folks,
I need some advice or suggestion to find out what is going on with my
network, we have notice high packet loss on openstack instance and not
sure what is going on, same time if i check on host machine and it has
zero packet loss.. this is what i did for test...
ping 8.8.8.8
