I'm wondering if anyone knows of a way to 'fix' these? EAL: Detected 8 lcore(s) EAL: Detected 1 NUMA nodes EAL: Detected static linkage of DPDK EAL: Selected IOVA mode 'VA' EAL: Probing VFIO support...

Reproduced by running testpmd with no arguments on Azure: - OS: Ubuntu 20.04 5.4.0-1048-azure - DPDK: 20.11.1 (LTS) - Networking: Azure Accelerated Networking (netvsc) OS setup is pretty minimal, nothing special other than DPDK is installed. I don't recall these errors happening while on bare metal - only on Azure. Thanks! Regards, Tyler
