Issues encountered during experiments with physical computers

Hi,did you run these code on real computer instead of virtual machine?

I'm learning dpdk on virtual machine and real computer using intel NIC.

Up to now,i run a program which can parse ARP and ICMP packets and send reply on a virtual machine,and ping it on another virtual machine successfully.When i use two real computer connected by RJ45 cable ,i have binding the NIC interface with igb_uio driver and run the code successfully ,but i fail to ping the ip address define in the program from another computer.

can you help me ,you are a good man

Hey!

I have not ran the DPDK examples I made on real hardware. All of my development and testing was done inside a virtual machine.

What example are you running when the ping stops replying? Is the behavior any different inside of the virtual machine you're running the example?

thank you for your reply

i run the example in https://github.com/betacat-code/dpdk-learning/blob/main/simple-app/ping/ping.c, and ping it from another machine(The IP address with the same subnet as IP address in ping.c has been configured.)

the program run successfully on real hardware same as inside the virtual machine ,no error.It just cannot be pinged.

i decide to find another example to learning. do you know any examples run successfully on hardware?and are there some good forums for DPDK that can help me？

thank you very much
