Please, describe the problem here and provide additional information below (if applicable) …

We built the front end and the node according to this procedure.

[https://docs.opennebula.org/5.4/deployment/opennebula\_installation/frontend\_installation.html](https://docs.opennebula.org/5.4/deployment/opennebula_installation/frontend_installation.html)

then I downloaded the image from APPS.  
and launched it.

I think that the key exchange is in the correct state.

Please tell me how to do the right thing.  
Thank you

From the frontend, what is the output of

`sudo su - oneadmin -c 'onehost list'`

`sudo su - oneadmin -c 'onehost show 0'`

And on the worker node:

`sudo systemctl status libvirtd`

I don’t know why libvirt is trying to use the 16509 port - that should be commented out by default in `/etc/libvirt/libvirtd.conf` on test6. I imagine you have no problems creating a test VM from test6 manually with virt-install, as root?

```
virsh list --all
grep oneadmin /etc/libvirt/qemu.conf # opennebula modifies this file
yum -y install wget virt-install virt-viewer
wget https://download.cirros-cloud.net/0.4.0/cirros-0.4.0-i386-disk.img -P /tmp
chown oneadmin:oneadmin /tmp/cirros-0.4.0-i386-disk.img
virt-install --os-variant=virtio26 --name=cirros --ram=64 --vcpus=1 --disk /tmp/cirros-0.4.0-i386-disk.img,format=qcow2 --import --nonetworks

```

In another terminal, with $DISPLAY available:

```
virt-viewer cirros # just check if it starts fine
virsh destroy cirros
virsh undefine cirros
```

Than you for your help. I can create VM from test6 manually with virt-install,as root.

I’m unable to reproduce the problem, maybe a developer can comment.

If you google search for “‘localhost:16509’: Connection refused” there are few posts that clarify what may be happening. If you find a solution please describe it here.

</div>

Could this be your problem?  
see: [https://access.redhat.com/documentation/en-us/red\_hat\_enterprise\_linux/7/html/virtualization\_deployment\_and\_administration\_guide/sect-troubleshooting-common\_libvirt\_errors\_and\_troubleshooting#sect-Unable\_to\_connect\_to\_server\_at\_host16509\_Connection\_refused\_](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/sect-troubleshooting-common_libvirt_errors_and_troubleshooting#sect-Unable_to_connect_to_server_at_host16509_Connection_refused_)…\_error\_failed\_to\_connect\_to\_the\_hypervisor

```
 The libvirt daemon was started without the --listen option. Verify this by running this command:

# ps aux | grep libvirtd
root 10749 0.1 0.2 558276 18280 ? Ssl 23:21 0:00 /usr/sbin/libvirtd

The output does not contain the --listen option. 

```

Solution  
Start the daemon with the --listen option.  
To do this, modify the /etc/sysconfig/libvirtd file and uncomment the following line:

```
# LIBVIRTD_ARGS="--listen"

Then, restart the libvirtd service with this command:

# /bin/systemctl restart libvirtd.service
```

Thank you for your help.  
I configured LIBVIRTD\_ARGS="–listen". but  
I could not start libvirtd.

I gave up Centos7 version.

I tried ubuntu16 version. now I perfectry set up opennebula.  
I think ubuntu version better.

Maybe after wrong opennebula packages reinstallations you’ve lost /var/lib/one/.ssh/config file, which manages ssh connections while clonning VMs.

As it is, workaround you can create config file with the next content:

```auto
Host *
  StrictHostKeyChecking no

```

But much more better to restore native opennebula config content
