I have a patch waiting in my working dir to cleanly disable vmxnet3-uio pmd. - If you don't bind vmxnet3 devices to uio, but forget to enable vmxnet3-usermap pmd (by specifiying -d librte_pmd_vmxnet3.so), then internal vmxnet3-uio pmd will try to initialise and crash. I did not look any deeper into this, the easiest way is to disable vmxnet3-uio pmd + apply the patch I will send in a few minutes, as a first workaround. Regards, -- David Marchand
