What is the error code it failed with?
There is no dependency between ESXi and DPDK versions as such. But depending
your VM settings, it may pop up some issues related to memory assigned to VM.
When you use NIC in Hypervisor and feed packets to VM via Vmxnet3, the guest OS
can use Vmxnet3-pmd
There were two line items on the 2.2 roadmap: Xen Driver and Hyper-V Driver.
Can you provide some more details?
Thanks,

For tuning ESXi and vSwitch for latency sensitive workloads, I remember the
following paper published by VMware:
https://www.vmware.com/files/pdf/techpaper/VMW-Tuning-Latency-Sensitive-Workloads.pdf
that you can try out.
The overall latency in setup (vmware and dpdk-vm using vmxnet3) remains
That's correct. If you're using dpdk packaged vmxnet3 pmd, you should be able
to bind it to igb_uio in Guest OS and start l2fwd/ l3fwd app in VM.
On the ESXi part, your vmxnet3 device must be connected to one of the vSwitches
with Uplink port, so you don't need to configure anything else, I
You can pass uio device to docker container with below command line, or you can
mount the volume /dev to container to allow all devices.
docker run -it --rm --privileged --device=/dev/uio0:/dev/uio0
--device=/dev/uio1:/dev/uio1 -v /mnt:/mnt fedora20-dpdk-2 /bin/bash

Just curious - I didn't understand the usage model here. In the Amazon EC2
instance (a VM,) do you want to run a DPDK application? Where do you intend to
run OVS?
As far I remember, OVS has a datapath in Host kernel and you won't be given
Host access by AWS. And I'm not sure if Amazon

Hi Aziz,
Yes, you're right DPDK VMXNET3-PMD in /lib/librte_pmd_vmxnet3 does not support
mbuf chaining today. But it's a standalone bsd driver just like any other pmd
in that directory, it does not need vmxnet3-usermap.ko module.

It really depends on the devices offered in the VM. If direct device assignment
is not provided to a VM or if the node hypervisor doesn't have an optimized
para-virtual interface to a VM, I don't see any benefit using DPDK in VMs.

I think if he's using OTP framework, it has some interfacing for other
languages as well, but not sure how efficient it's. In order to keep up with
the performance, it's better to evaluate those interfaces first.

We should not compare Vmxnet3-PMD with ixgbe-PMD performance as Vmxnet3 device
