[ovirt-users] Centos 7

[Koen Vanoppen]

Dear All,

We currently are running ovirt 3.5.1-1.el6 in production...
Our hypervisors are on centos 6.7 for the moment. But these will be changed
to centos 7.2 before we are going to upgrade the engine to centos 7 and
ovirt 4.
This is the plan:

   1. Migrate the current production server to centos 7 (of course NO data
   loss)
   2. Migrate the local engine DB to a external postgresDB
   3. Upgrade ovirt to the latest version (4.x)

Steps already tested and validated (on development):

   1. Update 3.5.1-1.el6 to latest 3.6 --> no issue
   2. Migrate the localdb to external db --> no issue
   3. Installed the same version on centos 7 (latest 3.6) --> no issue

And then the problems begin:
If I then connect the new install on centos 7 and run engine-setup, I get
the following output:

-== END OF CONFIGURATION ==--

          An existing DWH is configured to work with this engine.
          Its hostname is ovirtmgmt03dev.brusselsairport.aero.
          A positive answer to the following question will cause the
existing DWH to be permanently disconnected from the engine.
          A negative answer will stop Setup.
          Do you want to permanently disconnect this DWH from the engine?
(Yes, No) [No]: Yes

Does somebody has a idea to fix this?
Or is there already some guide to migrate your ovirtmgmt server on centos6
--> centos7 ?

Kind regards,
