Hi Yukihiro, Brian

Thank you very much for the help.
We were able to solve the vpp issue by setting cpu_mode to host-model
in /etc/nova/nova-cpu.conf.

All the interface came up in both packet generator and firewall VM vpp.

Packet generator VPP
vpp# show int addr
local0 (dn):
pg0 (up):
tap-0 (up):
192.168.10.200/24

Firewall VPP
vpp# show int addr
local0 (dn):
tap-0 (up):
192.168.10.100/24
tap-1 (up):
192.168.20.100/24

Traffic generator seems to sending traffic to the sink VM.

However the traffic is not received by the sink VM.

We tried to see if the Firewall VM interface received the traffic and forwarded 
to the sink.
However the traffic is not received by the interface facing towards packet 
generator interface.

ubuntu@vofwl01fwl3e18:~$ sudo tcpdump -i eth1
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes
^C
0 packets captured
0 packets received by filter
0 packets dropped by kernel


We were also unable to ping between packet generator vpp interfaces ips to 
firewall vpp interface ips.
root@vofwl01pgn3e18:~# vppctl
vpp# ping 192.168.10.100
unknown input `ping 192.168.10.100'
vpp#

We would be grateful if you are familiar with this issue and guide us to solve 
it.

Best Regards
Santosh Thapa Magar

Hi, 

I think you need to set the flag sse4_2 in vppctl.
I think one way to enable it is to set cpu_mode = host-model.
Therefore, it is recommended to set [cpumode = host-model] in 
/etc/nova/nova.conf, not [cpu_mode = host-passthrough].
