Walkthrough

The change modifies warning detection logic in a test file by replacing a simple exclude-and-grep approach with a more comprehensive ignore strategy. An ignore_patterns string is introduced to filter out specific warnings related to qemuDomainObjTaintMsg and virQEMUCapsInit, which are then excluded using grep -Ev before checking for remaining warnings. The command is executed with shell mode enabled and its result determines test pass/fail status.
