Walkthrough

A single configuration file for libvirt virtual network testing is updated to add an explicit line disabling s390-virtio architecture support under the basic_os/variants section of the iface_rom_disable_pxe_boot test configuration. This is a test infrastructure modification with no changes to code logic or public declarations.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~2 minutes

This is a minimal, single-line addition to a test configuration file with clear intent and no logic implications.

8-8: LGTM! Appropriate architecture exclusion.

The exclusion of s390-virtio is correct, as s390x architecture doesn't use ROM/BIOS concepts that this test validates. The placement ensures the entire test is skipped on s390x systems.
