[dpdk-users] cannot build l2fwd in dpdk 21.05 on window

[Phạm Thị Dân]

Hi,

I'm looking for help with my setup.

I successfully built DPDK 21.05 on Windows Server 2019 on VMware Workstation.
But when I build l2fwd, this error occurs:

EAL: Error - exiting with code: 1

Cause: No Ethernet ports - bye


I successfully installed NetUIO driver.

I tried to bind VMXNET3 devices to DPDK NetUIO driver following
instructions in dpdk-kmods-main/windows/netuio/README.

But, in Device Manager, this error occurs:

*"This device cannot start."*

Thanks

Which version exactly are you testing (commit hash and/or patches applied)?
Patches enabling vmxnet3 in DPDK and NetUIO are only being merged now.

Have you set up your system per <https://doc.dpdk.org/guides/windows_gsg>?
Please post full debug logs.

vmxnet3 PMD is not enabled in this commit.
You can enable it with trivial patch:

You didn't give a commit hash, but probably this has vmxnet3.
