But what if the hosts already existed before? Can I 1) delete host from engine gui 2) remove ovirt packages from host 3) verify also /var/lib/vdsm is removed 4) reboot host and verify all ok as a standalone server 5) add the host to the engine Will step 5) have problems because y host is sort-of-already-known by the engine before? Also, is it expected that if I set another network as mgmt one for a cluster, still I cannot remove the default ovirtmgmt network from that cluster? Thanks Gianluca
