Re: [vpp-dev] VPP Vnet crash with vhost-user interface

Ravi, I don't think you can declare (2) works fine yet. Please bring up the dpdk vhost-user interfaces and try to send some traffic between them to exercise the shared memory region from dpdk virtio-user which may be "questionable". VirtualFunctionEthernet4/10/4 1down Virtua

Hi all, I'm just checking in to see if anyone made progress on syslog? I've tried to look at the code and submit a patch myself to no avail. Thanks. On Sun, Apr 8, 2018 at 11:44 PM, Matus Fabian -X (matfabia - PANTHEON TECHNOLOGIES@Cisco) wrote: > Deterministic NAT is dedicated to CGN so no lo

Re: [vpp-dev] VPP Vnet crash with vhost-user interface

Hi Steven, I am testing both memif and vhost-virtio, unfortunately memif is not working as well. I posted question to the list, let me know if something is wrong. Below is the link https://lists.fd.io/g/vpp-dev/topic/q_on_memif_between_vpp/20371922?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,

Re: [vpp-dev] VPP Vnet crash with vhost-user interface

Hi Steve, Thank you for your inputs, I added feature-mask to see if it helps in setting up queues correctly, it didn't so I will remove it. I have tried following combination (1) VPP->vhost-user (on host) and DPDK/testpmd->virtio-user (in a container) -- VPP crashes (2) DPDK/testpmd->vhost-user

Re: [vpp-dev] VPP Vnet crash with vhost-user interface

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 vd

Re: [vpp-dev] VPP Vnet crash with vhost-user interface

I am not sure what is wrong with the setup or a bug in vpp, vpp crashes with vhost<-->virtio communication. (1) Vhost-interfaces are created and attached to bridge-domain as follows create vhost socket /var/run/vpp/sock1.sock server feature-mask 0x4040 create vhost socket /var/run/vpp/sock2.s

Re: [vpp-dev] VCL and LD Preload

Ville, VCL is still under development and in the experimental phase. There are a number of known issues and it has yet to be tuned for performance (connections per second, throughput, or latency) or scale. LDP was an early means of comparison testing the host stack .vs. the linux kernel, but

Dear Folks, I have a problem with vpp stateful mode.
