[dpdk-dev] "Incompatible UPT version” error when running DPDK on VMWare with VMXNET3 interface ,ESXI Version 6.5/6.7

[Puneet singh <Puneet.singh@truringsoftek.com>]

Hi Everyone,


We're trying to run DPDK test-pmd app in a guest machine running Red Hat 7.5. The host is ESXi version 6.5/6.7.

I'm building dpdk on the guest machine , I've tried both DPDK versions 18.08 and 17.11. We have created three interfaces on esxi for connection to our guest. One management port and two data ports. We're binding these two data ports to DPDK. The ports are all VMXNET3 interfaces.

I am using test-pmd application, it worked only when I start the app for first time. We are getting following error when I restart the application ,tried using the uio_pci_generic and igb_uio driver, same issue with both the driver.

Whenever I reboot the VM ,test-pmd works fine for first time ,if i restart the test-pmd it always giving following error.
