Hi Steven
Shared memory is setup correctly. I am seeing following errors. System
on which there is no crash it doesn't support 1G hugepages. So I have
to use 2M hugepages with following config for VPP.
(1) host
vpp# show error
CountNode Reason
vpp# show
Ravi,
I supposed you already checked the obvious that the vhost connection is
established and shared memory has at least 1 region in show vhost. For traffic
issue, use show error to see why packets are dropping. trace add
vhost-user-input and show trace to see if vhost is getting the packet.
Hi Ravi,
Sorry for diluting your topic. From your stack trace and show interface output
I thought you are using OCTEONTx.

Ravi,
I only have an SSE machine (Ivy Bridge) and DPDK is using ring mempool as far
as I can tell from gdb. You are using AVX2 which I don't have one to try it to
see whether Octeontx mempool is the default mempool for AVX2. What do you put
in dpdk in the host startup.conf? What is the output
Damjan, Steven,
Kindly let me know if anything I have messed up?
I have compiled VPP on x86_64 and done everything as suggested by Steven.
Thanks.

I am not intentional using it. I am running VPP on a x86 Ubuntu server.

Steven,
I managed to get Tx/Rx rings setup with 1GB hugepages. However, when I
assign an IP address to both vhost-user/virtio interfaces and initiate
a ping VPP crashes.
Any other mechanism available to test Tx/Rx path between Vhost and
Virtio? Details below.
***On host***

Ravi,
In order to use dpdk virtio_user, you need 1GB huge page.

Ravi,
Do this
1. Run VPP native vhost-user in the host. Turn on debug "debug vhost-user on".
2. Bring up the container with the vdev virtio_user commands that you have as
before
3. show vhost-user in the host and verify that it has a shared memory region.
If not, the connection has a problem.
Hi Steven,
Thanks for your help. I am using vhost-user client (VPP in container)
and vhost-user server (VPP in host). I thought it should work.
create vhost socket /var/run/vpp/sock3.sock server (On host)
create vhost socket /var/run/usvhost1 (On container)
Can you please point me to a
Ravi,
VPP only supports vhost-user in the device mode. In your example, the host, in
device mode, and the container also in device mode do not make a happy couple.
You need one of them, either the host or container, running in driver mode
using the dpdk vdev virtio_user command in
Hi Steven
Though crash is not happening anymore, there is still an issue with Rx
and Tx. To eliminate whether it is testpmd or vpp, I decided to run
(1) VPP vhost-user server on host-x
(2) Run VPP in a container on host-x and vhost-user client port
connecting to vhost-user server.
Still doesn't
show interface and look for the counter and count columns for the corresponding
interface.

i have tested following scenarios and it basically is not clear why

Ravi,
I've proved my point -- there is a problem in the way that you invoke testpmd.
The shared memory region that it passes to the device is not accessible from
the device. I don't know what the correct options are that you need to use.
This is really a question for dpdk.

Hi Steven,
Thank you for your help, I removed sock1.sock and sock2.sock,

Hi Steven,
I am testing both memif and vhost-virtio, unfortunately memif is not

something is wrong. Below is the link
Ravi,
First and foremost, get rid of the feature-mask option. I don't know what
0x4040 does for you. If that does not help, try testing it with dpdk based
vhost-user instead of VPP native vhost-user to make sure that they can work
well with each other first. To use dpdk vhost-user, add a
Steve,
Thanks for inputs on debugs and gdb. I am using gdb on my development
system to debug the issue. I would like to have reliable core
generation on the system on which I don't have access to install gdb.
I installed corekeeper and it still doesn't generate core. I am
running vpp inside a VM
Ravi,
I install corekeeper and the core file is kept in /var/crash. But why not use
gdb to attach to the VPP process?
To turn on VPP vhost-user debug, type "debug vhost-user on" at the VPP prompt.

Hello,
I have a VM(16.04.4 Ubuntu x86_64) with 2 cores and 4G RAM. I have
installed VPP successfully on it. Later I have created vhost-user
interfaces via
create vhost socket /var/run/vpp/sock1.sock server
create vhost socket /var/run/vpp/sock2.sock server
set interface state
