virt-manager: ssh-askpass "No such file or directory"

[peter_b]

[PROBLEM]
Tried to connect to a KVM virtual machine client, using a fresh install of "virt-manager" on Ubuntu 12.04.
The connection was kvm over SSH, but I got the following error message (sorry. German):

Verbindung mit libvirt nicht möglich:

Kann keine Daten empfangen: ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory
Permission denied, please try again.
ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory
Permission denied, please try again.
ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
: Die Verbindung wurde vom Kommunikationspartner zurückgesetzt

Verify that:
- The 'libvirt-bin' package is installed
- The 'libvirtd' daemon has been started
- You are member of the 'libvirtd' group

[SOLUTION]
It already says: "/usr/bin/ssh-askpass" doesn't exist.
Just install any "ssh-askpass" package that fits your envirionment.
For example:

• "ssh-askpass": simple, rather ugly generic X11 GUI input-dialog
• "ssh-askpass-gnome": GUI input-dialog for Gnome/X11

[PROBLEM]
After installing "ssh-askpass-gnome", I was greeted with another error message:

Verbindung mit libvirt nicht möglich:

Verify that:
- The 'libvirt-bin' package is installed

It claims to be unable to find the "nc" command.
On the local machine I'm trying to connect from, it is installed however...

[SOLUTION]
My fault. I got confused and tried to connect virt-manager to the actual KVM-client, not the server!
The client was RHEL 6 and didn't have the "nc" command installed by default.

In the end good, because I was definitely trying to connect to the wrong machine.
