Job Aborted Failure In Uio Create Address From Ip Address Link [ PRO | SECRETS ]

The application tries to map an IP address that does not exist on any active link (interface). This can happen if:

sudo systemctl restart networking

Or, on some distributions:

sudo service networking restart

To understand the failure, we must decompose the error message: The application tries to map an IP address

The Core Issue: The application requested access to a network interface (identified by IP) via the UIO driver, but the kernel or driver rejected the mapping request.

UIO stands for Userspace I/O. It is a Linux kernel framework that allows device drivers to be written mostly in user space, rather than inside the kernel. UIO is commonly used for network interfaces, custom FPGA cards, and high-speed data acquisition devices. A failure in UIO means the user-space driver could not communicate properly with the hardware or kernel module. To understand the failure, we must decompose the

The UIO driver (e.g., uio_pci_generic or a vendor-specific module) is not loaded or not bound to the correct network device. Without a proper UIO binding, the user-space application cannot "create an address" from the IP/link because it cannot access the device memory.

Ensure the IP address referenced in the job configuration actually exists on an active interface. ranked by likelihood:

ip addr show

The network interface you’re targeting is not bound to a UIO-compatible driver (like igb_uio, vfio-pci, or uio_pci_generic).

Symptom:
lspci -k shows the NIC using a kernel driver like ixgbe, igb, or e1000e instead of a UIO driver.
