RHEV- Error importing VMs

Description of problem:

I'm not able to import virtual machines from KVM (Virt-Manager) to Red Hat Virtualization.

Version-Release number of selected component (if applicable):

- RHEV 4.05
- KVM Host: Fedora 23
- RHEV-H: RHEL 7.3
- RHEV-M: RHEL 7.3

* HOST and MANAGER are running in the same hardware.

How reproducible:

Steps to Reproduce:

1. Log in to the proxy host and generate SSH keys for the vdsm user.

    # sudo -u vdsm ssh-keygen

2. Copy the vdsm user's public key to the KVM host.

    # sudo -u vdsm ssh-copy-id root.com

3. Log in to the KVM host to add it to the proxy host's known_hosts file.

    # sudo -u vdsm ssh root.com

4. Log in to the Administration Portal. In the Virtual Machines tab, click Import to open the Import Virtual Machine(s) window. 

5. Select the Data Center that contains the proxy host.

6. Select KVM (via Libvirt) from the Source drop-down list.

7. Enter the URI of the KVM host in the following format:

   qemu+ssh://root.com/system

8. Keep the Requires Authentication check box selected.

9. Enter root in the Username field.

10. Enter the Password of the KVM host's root user.

11. Select the Proxy Host from the drop-down list.

12. Click Load to generate a list of the virtual machines on the KVM host.
