Created attachment 1340650 [details] engine logs Description of problem: Cluster can be created with empty 'Default network provided', which is causing host deploy process to fail with 'Failed to configure management network on the host' and NPE is shown in the logs. The cause of that is most probably that 'Default network provided' combo box is empty, so no value can be set into it Version-Release number of selected component (if applicable): master, Change-Id: I4b5338e4faa5e5dd36872a4772f86dca809a37bb How reproducible: 100% Steps to Reproduce: 1.
