Hello Richard / Shahar, I installed and enabled nc on Xen Server host. Now the " ...... sh: nc: command not found: Input/output error" is gone. Communication is established. However I am still getting two specific errors: VDSM ovirt_engine command failed: End of file while reading data: : Input/Output error & Failed to retrieve VMs Information from the external server xen+ssh://root@192.168.1.40 I am receiving the same error when I run virsh -c xen+ssh://root@192.168.1.40 Screen shot is attached for quick reference. Is it something to do with firewall / ip tables on xen server or libvirtd host? -- Thanks & Regards, Anantha Raghava Do not print this e-mail unless required. Save Paper & trees.

Yes, you need to install 'nc' on the *target* (Xen) machine.
This is because libvirt's ssh transport uses nc: https://libvirt.org/guide/html/Application_Development_Guide-Architecture-Tr... <https://libvirt.org/guide/html/Application_Development_Guide-Architecture-Transports.html>
