Description of problem:
If openssh-askpass which provides /usr/libexec/openssh/ssh-askpass not installed on the system and remote ssh connection needs password input, 
users cannot connect to the remote livritd w/ virt-manager.

To fix this, how about making libvirt or libvirt-python or virt-manager
depends on openssh-askpass (Requires: openss-askpass) ?


Version-Release number of selected component (if applicable):
Confirmed w/ libvirt*-0.9.6-4.fc16 and virt-manager-0.9.0-7.fc16,
libvirt-0.9.9-2 and virt-manager-0.9.0-8? (koji HEAD)

 
How reproducible: always under certain specified conditions (ssh 
connection needs password input and /usr/libexec/openssh/ssh-askpass
is not available)


Steps to Reproduce:
1. Start virt-manager
2. Create remote connection (ssh; the remote host needs password input)
3. Connect that remote host
  

Actual results: Could not connect remote host via ssh as ssh-askpass is missing
