Hi, today we have merged patches into master and ovirt-engine-3.6 branch, which eases configuration of WildFly overlay in development environment: 1. If you are using WildFly for development (preferred option), you should build engine using: make clean install-dev PREFIX=$HOME/ovirt-engine When the build is finished successfully, WildFly overlay configuration is created automatically in $HOME/ovirt-engine/etc/ovirt-engine/engine.conf.d/20-setup-jboss-overlay.conf There's no need to any manual configuration. 2. If you are using EAP6 for development, from now you should build engine using: make clean install-dev PREFIX=$HOME/ovirt-engine WILDFLY_OVERLAY_MODULES="" Using this option, WildFly overlay won't be configured, so you can use EAP6. More information about build options can be found at README.developer. Martin Perina
