Job Aborted Failure: In Uio Create Address From Ip Address Link

Use MAC addresses to identify the correct interface in your script:

Add a custom udev rule:

lspci -vvs 02:00.0 | grep "Kernel driver" # Use actual PCI id If it shows a kernel driver (e.g., ixgbe ), unbind it and bind to UIO: Use MAC addresses to identify the correct interface

# For DPDK-style binding dpdk-devbind.py -b igb_uio 02:00.0 # Or manually echo 0000:02:00.0 > /sys/bus/pci/drivers/ixgbe/unbind echo 0000:02:00.0 > /sys/bus/pci/drivers/uio_pci_generic/bind Run these checks as the same user that executes the job: /sys/bus/pci/drivers/ixgbe/unbind echo 0000:02:00.0 &gt
