SSH authentication problem in Ubuntu under Virt-manager

Under Ubuntu, regardless of whether you use the APT installation (sudo apt-get install virt-manager) or the Software Center installation Virt-manager will encounter an issue that does not eject the authentication box when connected to the host:

"You need-install Openssh-askpass or similar to connect to this hos"

Workaround:

Method One: In the terminal using Virt-manager--no-fork to start the Virt-manager, but this method has a problem is that each time you enter the password is required in the terminal input, very troublesome.

Method Two: Install Ssh-askpass-gnome to allow popup authentication box:

sudo apt-get install Virt-manager ssh-askpass-gnome--no-install-recommends
