Hi @all, first my system: OS: Scientific Linux 6.0 Hypervisor: KVM + libvirt I got the following error /*error : remoteDispatchAuthPolkit:3799 : Policy kit denied action org.libvirt.unix.manage from pid 2381*/ when I want to connect with: /*virsh -c qemu:///system*/ to the hypervisor with a new added user. The user is in in kvm and qmeu group and the connection with virsh -c qemu://$hostname/system works fine. Also root login with the "login" works fine. I configured libvirt to use TLS-authetification... Did anyone of you have a solution to solve this problem.
