Description of problem:

Because virt-manager has no Requires: openssh-askpass, these errors occur when attempting to connect to a remote QEMU over SSH:

Unable to open a connection to the libvirt management daemon.

Libvirt URI is: qemu+ssh://root@someremotehost/system

Verify that:
 - The 'libvirtd' daemon has been started
