netmap: Error: Unable to open netmap:eth0: Invalid argument in AWS

Hello, I installed netmap in AWS(Ubuntu 16.04) . When I run $ pke-gen -i eth0 , I got these error message:

065.096883 main [2855] interface is eth0

Is there any special settings when I use the virtual server in AWS, GCP, etc Thanks.

Hi, vmaffione.

Thank you for your explanation.

I use ip link set dev etho mtu 2000 to set MTU.

But when I run $ pkt-gen -i eth0 ,the terminal frozen in these messages.

065.096883 main [2855] interface is eth0
065.097475 main [2977] using default burst size: 512

065.097828 extract_ip_range [467] range is 10.1.0.1:1234 to 10.1.0.1:1234

Several minutes later, I lost the connection with my AWS.

And I got this message in dmesg.
