[ovirt-users] error starting vm - configure network

I have just installed ovirt AIO. I configure local datacenter, local storage. Created a new vm. Attached a cd. But when I want to "Run once", so I can install de OS, i get these events and the vm shuts immediately down: 2015-jun-04, 13:21 Failed to run VM debTest2 (User: admin@internal). 2015-jun-04, 13:21 Failed to run VM debTest2 on Host local_host. 2015-jun-04, 13:20 VM debTest2 is down with error. Exit message: XML error: listen network 'vdsm-ovirtmgmt' had no usable address. 2015-jun-04, 13:20 VM debTest2 was started by admin@internal (Host: local_host). I suppose I have to configure network. But don't know how to proceed. Thank you for your help. -- Gonzalo Amadio La simplicidad es la sofisticación suprema
