[Pkg-libvirt-maintainers] Bug#641083: virt-manager: Unable to establish qemu+ssh connection due to no prompt for password

[Jonathan Wheelhouse]

Package: virt-manager
Version: 0.9.0-1
Severity: normal

(This is similar to bug 614291 but the cause is different.)

I have successfully used virt-manager to connect to a libvirt managed
KVM server via SSH in the past.

I'm not sure what caused the failure, but for the previously working
qemu+ssh://jonathan@patonga/system connection I now get the following
error message.

------------------------------------------------------------------------
Unable to open a connection to the libvirt management daemon.

Libvirt URI is: qemu+ssh://jonathan@patonga/system

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

------------------------------------------------------------------------

ssh-askpass doesn't give me a dialog to enter a password.  That, I
think, is the problem.

And, if I start the remote virtual machine via virsh then I can use
virt-viewer to connect to the virtual machine's graphical console.
