Hi Soeren,

Yes! That works perfectly. Did it myself several times.

Hi Vered,

Thanks for the quick answer, ok, understood

Then i could create a new Cluster in the same datacenter with newly installed hosts and then migrate the machines through shutting them down in the old cluster and then starting them in the new cluster, only thing i loose is the live migration

Hi Soeren,

oVirt Clusters support one host distribution (all hosts must be of the same distribution).
If the cluster is empty at one point, you can add a host of a different distribution than the cluster occupied before.
But there can't be two type of distributions at the same time in one cluster.

Vered

Dear all,

Would it be possible to switch from fedora 20 to centos 7.1 (as far as i
understood it has live merge support now) within one cluster, meaning


    * take out one compute host
    * Reinstall that compute host with Centos 7.1
    * Do a hosted-engine —deploy
    * Migrate VM to the CentOS 7.1 host
    * Take the next fedora host and reinstall

Any experiences, recommendations or remarks on that ?

Regards
Soeren
