Hi, WildFly 8 is currently required for oVirt master and 3.6, ONLY following versions should be used (as it's declared in ovirt-engine.spec.in): ovirt-engine-wildfly-8.2.1-1.el7.x86_64.rpm ovirt-engine-wildfly-overlay-8.0.4-1.el7.noarch.rpm Please assure that you have installed those versions on your development machines. Please be aware that there are also newer WildFly 10 packages on ovirt-master-snapshot-static repositories: ovirt-engine-wildfly-10.0.0-0.3.el7.x86_64.rpm ovirt-engine-wildfly-overlay-10.0.0-1.el7.noarch.rpm These packages should be used only to test patches that migrates WildFly to version 10 for oVirt 4 and SHOULD NOT BE USED OTHERWISE. So if you accidentally installed those packages, please downgrade to WildFly 8. Thanks Martin Perina
