@sudo87 what (if any) is the functional trade-off for this? |

Author
No functional trade-off, KVM never uses the CXF jar. This exclusion is scoped to plugins/hypervisor/kvm only. |

@nvazquez a [SL] Jenkins job has been kicked to build packages. It will be bundled with KVM, XenServer and VMware SystemVM templates. I'll keep you posted as I make progress. |

How Has This Been Tested?
Dependency tree check: confirms CXF is no longer resolved for the KVM plugin module:
mvn dependency:tree -pl plugins/hypervisors/kvm -Dincludes=org.apache.cxfoutput is empty after the fix
Build artifact check: confirms no CXF jars are copied into the agent's dependency bundle
ls plugins/hypervisors/kvm/target/dependencies | grep -i cxfno result
How did you try to break this feature and the system with this change?
