(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.

HI,
I was having the same problem in Oneiric 64 bit. I was using the
cmd line to launch virt-manager using  $ virt-manager.  The issue was
solved when:
a. I had installed ssh-askpass into my system
b. I started using GUI and not cmd line to launch virt-manager. When
cmdlink is used we get some GTK warnings which may also be the cause of
the issue.

Regs,
Deepak
