Now I have done it.

I was adding a new cluster and storage domain to my ovirt enviroment.

At the end of the day I was sucsesful in doing so. Had some issues but after carefully reading the manuals got it working just fine.

So now I have added a new CLUSTER002 with it's own datastorage DATA_2_DOMAIN.

Then I started changing the existing default cluster name to CLUSTER001 and changing the network from VM to VM_ROMULUS and also changed the DATA_DOMAIN to DATA_1_DOMAIN.

Apparently this is a bad idea as I can see all my VM's but can't start them because my ovirt enviroment tell's me the following : Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details.

And then nothing.

So for now I 'm exporting importing the VM to my new DATA_2_DOMAIN from DATA_1_DOMAIN, which seems to work, to be able to start my VM as I need it realy quickly but how am I going to fix my optimistic changes ?

Kind regards.
