Re: [Users] error when regestering a host with vdsm 4.9.6 in ovirt 3.1

I have built and installed the latest RPM ovirt-engine from the source on F16 and the latest RPM VDSM 4.9.6 on F17 because of nedeed dependancies. when I add a new host, installation always fails with this issue : Failed to install Host khamsin. Step: CreateConf; Details: Basic configuration failed to import default values. I tried to disable ssl in engine and vdsm but it is the same. I have searched more explications into vdsm and ovirt log but I have found anything I suppose vdsm to be the problem, the only way to build it with success is to install it on F17, which is a beta release... This makes me crazy! May anybody help me to find a clue for this issue?
