Hi, The reason the error shows is because with apt-get your user is not added to the necessary group. this should somehow be handled within the install script. a logoff/login is then required to get that setting activated (though there should be another way in linux).
Hope this helps. the link: https://help.ubuntu.com/community/KVM/Installation ---QUOTE--- You need to ensure that your username is added to the group libvirtd: $ sudo adduser `id -un` libvirtd Adding user '<username>' to group 'libvirtd' ...
