I had a previous Datacenter and Cluster with a Host in it which I have removed completelly from oVirt Engine. In order to remove I did the following steps: - Removed all Virtual Machines on the top of the Host - Put the only Local Datastore in Maintenence mode (It didn't allow to remove it for some reason. Said I had to remove the Datacenter instead) - As the Datastore couldn't be remove so the Host. I then removed the Datacenter and it removed everything. Then I created a new Cluster and tried to add the same Host with the same hostname in it and I am getting the message: "Cannot add Host. The Host name is already in use, please choose a unique name and try again." It seems that something was left lost in the Database which still beleives that host exists in oVirt Engine. How can I clean that up and add it again as I am not willing to change its name. Thanks Fernand --------------3A9AA83C242C9D0BB163DB52 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> </head> <body bgcolor="#FFFFFF" text="#000000"> <font face="arial, helvetica, sans-serif">Hello.<br> <br> I had a previous Datacenter and Cluster with a Host in it which I have removed completelly from oVirt Engine.
