Hi,
When the DPDK UDP packets pass from guest machine to host using KVM SRIOV
the source IP address in the IP header of the UDP packet is changed.The
changed IP address is not configured in the host machine either.The
ifconfig output doesn't show this IP.How this IP address can change in the
host?what configurations do I need to check and how to prevent this IP
address change.
Regards,
Anupama

Are you really using KVM SRIOV or is it a virtio device with NAT?
