Adding a new compute libvirt resource results in an error if testing the connection to the hypervisor:

Warning!
Error making a connection to libvirt URI qemu+ssh://root@coshv1.localdomain/system: Call to virConnectOpen failed: Cannot find 'ssh' in path: No such file or directory

Full trace
Fog::Errors::Error
Error making a connection to libvirt URI qemu+ssh://root@coshv1.localdomain/system: Call to virConnectOpen failed: Cannot find 'ssh' in path: No such file or directory

The ssh key exchange with the hypervisor works fine for the foreman user from the command line:

[root@cosdpl1 ~]su foreman -s /bin/bash
bash-4.2$ ssh root@coshv1.localdomain
Last login: Thu Sep 18 11:11:23 2014 from 141.73.53.249
[root@coshv1 ~]# exit
logout
Connection to coshv1.localdomain closed.
bash-4.2$ virsh -c qemu+ssh://root@coshv1.localdomain/system
Welcome to virsh, the virtualization interactive terminal.

Type: 'help' for help with commands
'quit' to quit

virsh # exit
bash-4.2$ exit
exit
[root@cosdpl1 ~]#

If the compute resource will be created anyway, ignoring the connection error, there is no interaction possible with is compute resource.
For example, pushing the "Assosiate VMs" button results in the same error.
