[ovirt-users] Remove default cluster

Hello, I finished upgrading a 3.5.1 DC that contained some CentOS 6.6 hosts. For that, I added a second cluster in which I progressively moved my upgraded hosts into CentOS 7. Now my old cluster is empty, and the new one contains my CentOS 7 hosts. I'd like to get rid of the old empty cluster, but when trying to delete it, oVirt explains that some template are still used in this cluster. Actually, I have only the default blank template and another custom one. Once the custom one has easily been moved, I have no way to move the blank one because every action is greyd out. I guess no one will tell me to play with psql... :) -- Nicolas ECARNOT
