[ovirt-devel] cannot install host: VdsDeployBase, Error during deploy dialog: java.lang.NullPointerException

Hi, I have difficulties to install host. I do believe it fails due to this: 2015-06-24 08:29:26,729 ERROR [org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase] (VdsDeploy) [612066b7] Error during deploy dialog: java.lang.NullPointerException at org.ovirt.otopi.dialog.MachineDialogParser.cliEnvironmentGet(MachineDialogParser.java:236) [otopi.jar:] at org.ovirt.engine.core.bll.hostdeploy.VdsDeploy$43.call(VdsDeploy.java:579) [bll.jar:] at org.ovirt.engine.core.bll.hostdeploy.VdsDeploy$43.call(VdsDeploy.java:577) [bll.jar:] at org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase._nextCustomizationEntry(VdsDeployBase.java:202) [bll.jar:] at org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase._threadMain(VdsDeployBase.java:301) [bll.jar:] at org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase.access$200(VdsDeployBase.java:45) [bll.jar:] at org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase$7.run(VdsDeployBase.java:392) [bll.jar:] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.7.0_79] anyone met this?
