I can successfully run the "kni" example program in DPDK (version 20.08) on RHEL 8 over KVM (with the PMD 'virtio').
Then I changed to run this "kni" on RHEL 8 over vmware (with the PMD 'vmxnet3').

If I started this "kni" to use 2 ports:

    ./kni -c 0x1f -n 4 -- -P -p 0x3 --config="(0,1,2),(1,3,4)"

It hanged (the console is also frozen) when initializing the 2nd port (initializing the 1st port is OK).



If it is started to use 1 port only:

./kni -c 0x07 -n 4 -- -P -p 0x1 --config="(0,1,2)"

It could start successfully but also hanged when I killed this program (using kill -9). Actually, I am not sure the VM hanged or not because all network interfaces were gone when the program "hanged" -- I was forced to log out since I connected to the VM by a SSH session.

The "kni" program runs perfectly when on RHEL 8 over KVM so no need to question about the environment settings and the above command line arguments. The only difference, I think, is the PMD. It is suspected that there may be some problems in the PMD 'vmxnet3'.

Anyone can successfully run DPDK (20.08) KNI application on RHEL 8 over vmware ?
