[libvirt] ssh not working with libvirt

Hi, I am having issue while doing *ssh* to a virtual node through libvirt. The nodes's ip address is 192.168.82.1. When I am giving the command it is giving the following error message: *virsh# connect vbox+ssh://192.168.82.1/session* *Password:* *error: Failed to connect to the hypervisor* *error: End of ifle while reading data: sh: nc: command not found: Input/output error.* Can anyone tell me why am I facing this problem and how to resolve it. Thanks in advance.
