I was able to get the Fedora rpms installed using https://copr.fedorainfracloud.org/coprs/nucleo/freerouter/

My hw.txt:

hwid emu

port 63000 64000

int eth0 eth - 127.0.0.1 22710 127.0.0.1 22709

!int eth1 eth 0000.0A00.02FE 127.0.0.1 22712 127.0.0.1 22711

!line tty1 127.0.0.1 21003 127.0.0.1 21003

tcp2vrf 2323 v1 23

tcp2vrf 2001 v1 22

tcp2vrf 9080 v1 9080

!tcp2vrf 8080 v1 80

/bin/p4dpdk.bin -- 127.0.0.1 0 9080 0 1 2   1 3 4

I have added the hugepages and also moved 2 interfaces into vfio-pci:

[ec2-user@ip-172-31-38-199 ~]$ dpdk-devbind.py -s

 

Network devices using DPDK-compatible driver

============================================

0000:00:06.0 'Elastic Network Adapter (ENA) ec20' drv=vfio-pci unused=ena

0000:00:07.0 'Elastic Network Adapter (ENA) ec20' drv=vfio-pci unused=ena

 

Network devices using kernel driver

===================================

0000:00:05.0 'Elastic Network Adapter (ENA) ec20' if=eth0 drv=ena unused=vfio-pci *Active*

 

No 'Baseband' devices detected

==============================

But sdn interface shows down:

[root@ip-172-31-38-199 ~]# telnet localhost 2323

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

The free-router service is starting without any errors:

Not sure where the problem could be? Also how can I debug if the dpdk process is having issues?
