This error throws every time when I try to start the VM: 2017-07-31 16:51:07,297+02 ERROR [org.ovirt.engine.core.bll.RunVmCommand] (default task-239) [7848103c-98dc-45d1-b99a-4713e3b8e956] Error during ValidateFailure.: java.lang.NullPointerException at org.ovirt.engine.core.bll.scheduling.SchedulingManager.canSchedule(SchedulingManager.java:526) [bll.jar:] at org.ovirt.engine.core.bll.validator.RunVmValidator.canRunVm(RunVmValidator.java:157) [bll.jar:] at org.ovirt.engine.core.bll.RunVmCommand.validate(RunVmCommand.java:967) [bll.jar:] at org.ovirt.engine.core.bll.CommandBase.internalValidate(CommandBase.java:836) [bll.jar:] at org.ovirt.engine.core.bll.CommandBase.validateOnly(CommandBase.java:365) [bll.jar:] at org.ovirt.engine.core.bll.PrevalidatingMultipleActionsRunner.canRunActions(PrevalidatingMultipleActionsRunner.java:113) [bll.jar:] at org.ovirt.engine.core.bll.PrevalidatingMultipleActionsRunner.invokeCommands(PrevalidatingMultipleActionsRunner.java:99) [bll.jar:] at org.ovirt.engine.core.bll.PrevalidatingMultipleActionsRunner.execute(PrevalidatingMultipleActionsRunner.java:76) [bll.jar:] at org.ovirt.engine.core.bll.Backend.runMultipleActionsImpl(Backend.java:640) [bll.jar:] at org.ovirt.engine.core.bll.Backend.runMultipleActions(Backend.java:610) [bll.jar:] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [rt.jar:1.8.0_141] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) [rt.jar:1.8.0_141] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.8.0_141] at java.lang.reflect.Method.invoke(Method.java:498) [rt.jar:1.8.0_141] at org.jboss.as.ee.component.ManagedReferenceMethodInterceptor.processInvocation(ManagedReferenceMethodInterceptor.java:52) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:340) at org.jboss.invocation.InterceptorContext$Invocation.proceed(InterceptorContext.java:437) at org.jboss.as.weld.ejb.Jsr299BindingsInterceptor.delegateInterception(Jsr299BindingsInterceptor.java:70) [wildfly-weld-10.1.0.Final.jar:10.1.0.Final] at org.jboss.as.weld.ejb.Jsr299BindingsInterceptor.doMethodInterception(Jsr299BindingsInterceptor.java:80) [wildfly-weld-10.1.0.Final.jar:10.1.0.Final] at org.jboss.as.weld.ejb.Jsr299BindingsInterceptor.processInvocation(Jsr299BindingsInterceptor.java:93) [wildfly-weld-10.1.0.Final.jar:10.1.0.Final] at org.jboss.as.ee.component.interceptors.UserInterceptorFactory$1.processInvocation(UserInterceptorFactory.java:63) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:340) at org.jboss.invocation.InterceptorContext$Invocation.proceed(InterceptorContext.java:437) at org.ovirt.engine.core.bll.interceptors.CorrelationIdTrackerInterceptor.aroundInvoke(CorrelationIdTrackerInterceptor.java:13) [bll.jar:] at sun.reflect.GeneratedMethodAccessor95.invoke(Unknown Source) [:1.8.0_141] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.8.0_141] at java.lang.reflect.Method.invoke(Method.java:498) [rt.jar:1.8.0_141] at org.jboss.as.ee.component.ManagedReferenceLifecycleMethodInterceptor.processInvocation(ManagedReferenceLifecycleMethodInterceptor.java:89) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:340) at org.jboss.as.ejb3.component.invocationmetrics.ExecutionTimeInterceptor.processInvocation(ExecutionTimeInterceptor.java:43) [wildfly-ejb3-10.1.0.Final.jar:10.1.0.Final] at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:340) at org.jboss.invocation.InterceptorContext$Invocation.proceed(InterceptorContext.java:437) at org.jboss.weld.ejb.AbstractEJBRequestScopeActivationInterceptor.aroundInvoke(AbstractEJBRequestScopeActivationInterceptor.java:73) [weld-core-impl-2.3.5.Final.jar:2.3.5.Final] at org.jboss.as.weld.ejb.EjbRequestScopeActivationInterceptor.processInvocation(EjbRequestScopeActivationInterceptor.java:83) [wildfly-weld-10.1.0.Final.jar:10.1.0.Final] .... etc...
