Ben,
Yes, thanks, I can now connect to google.ca through VPP in Azure!
Ok, in that case, do you recommend I open a separate thread for the VPP/NAT
discussion?
Thanks,
Chris

Ben,
I am still seeing some odd behaviour when trying to route traffic to the
Internet though (again from Azure). I've added a default route through
FailsafeEthernet2 and this is what I get when trying to connect to
www.google.ca on port 80 with netcat on a box on my 10.4.2.0/24 subnet:

Ben,
Yes, for instance, if I ping a new destination from a new source 10 times, I
will get 8 responses because the first 2 packets are dropped. Once the ARP
entries are in, the pings start going through:
ping -c 10 10.4.2.7
PING 10.4.2.7 (10.4.2.7) 56(84) bytes of data.
64 bytes from 10.4.2.7:

Ben,
I've done some testing and am now happy to report that my interfaces are
receiving and forwarding traffic! This is a great milestone - thanks!
I did, however, run into the ARP issues you mentioned. The first time I try to
hit a destination IP I notice the following:

Ben,
Here is the output you requested - I haven't really tested things yet, but the
devices seem to attach and the hardware says it's up! I think you were right
about running with LD_LIBRARY_PATH in the same runtime environment! There are
still some concerning error messages, but not sure that

Ben,
I tried what you suggested but it didn't work for me (yet) :-(. In order to
get the *glue* libraries to build I had to go into vpp/build/external/packages
and run 'make dpdk-install'. Then I set LD_LIBRARY_PATH (was previously unset)
and I issued the following commands:

Do you have LD_LIBRARY_PATH exported so that the DPDK can find the
librte_pmd_mlx[45]_glue.so.* library?
Eg. from the the vpp

Ben,
I'm glad you got it to work - thanks for the info!
Interestingly, I had already modified those 4 lines in dpdk.mk from 'n' to 'y'
and I still get the "EAL: Driver cannot attach the device" errors when starting
VPP.

Any pointers as to exactly how I would configure VPP to use the RDMA drivers?
What would I put in the vdev line in the VPP startup.conf?
Also, do you know if this is expected to work on Azure?
Thanks,
Chris

Thanks for your reply and for looping in Damjan.
I have had a fair bit of success initializing DPDK directly on this same box on
the same adapters. Both of the following testpmd commands work for me and the
interfaces are attached to properly:
sudo ./testpmd -l 0-3 -n 4
