Re: [ovirt-users] Migrating to a Hosted Engine does not work as expected. Cluster name/id problem?

Cluster name/id problem? Hi Simone, thanks for the tips! Neither the ovirt or Red Hat docs mentioned (or quite possibly I missed it) exactly what I should expect from the working hosted engine, so I was a bit confused. Good to know 3.6 will bring those! The last attempt log is attached. I don't have all the logs from previous tries anymore, sorry =(

Again about the docs: I believe I will request a wiki editor account if you guys are accepting. I noted a few points of confusion where I had to do a lot of guess work - an example is the storage domain for the hosted engine, it took me quite a bit of guessing to find out it was a separate domain =D
