Re: [ovirt-users] Importing Libvirt Kvm Vms to oVirt Status: Released in oVirt 4.2 using ssh - Failed to communicate with the external provider

Using the command line on the engine machine (as root) works fine. I don't use ssh key from the agent GUI but the authentication section (with root user and password), I think that it's a bug, I manage to migrate with TCP but I just want to let you know. is it possible to use ssh-key from the agent GUI? how can I get the key?
