<p><font face="Liberation Serif">I installed and enabled nc on Xen

I am still getting two specific errors:</p>

<p>I am receiving the same error when I run virsh -c
<a class="moz-txt-link-abbreviated" href="mailto:xen+ssh://root@192.168.1.40">xen+ssh://root@192.168.1.40</a></p>
<p>Screen shot is attached for quick reference.</p>
<p>Is it something to do with firewall / ip tables on xen server or
libvirtd host?<br>

Yes, you need to install 'nc' on the *target* (Xen) machine.<br>
<br>
This is because libvirt's ssh transport uses nc:<br>
