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

Hello there, I'm following https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt/ guide in order to import VMS from Libvirt to oVirt using ssh. URL: "qemu+ssh://host1.example.org/system" and get the following error: Failed to communicate with the external provider, see log for additional details. *oVirt agent log:* *- Failed to retrieve VMs information from external server qemu+ssh://XXX.XXX.XXX.XXX/system* *- VDSM XXX command GetVmsNamesFromExternalProviderVDS failed: Cannot recv data: Host key verification failed.: Connection reset by peer* *remote host sshd DEBUG log:* *Feb 7 16:38:29 XXX sshd[110005]: Connection from XXX.XXX.XXX.147 port 48148 on XXX.XXX.XXX.123 port 22* *Feb 7 16:38:29 XXX sshd[110005]: debug1: Client protocol version 2.0;
