Virt-manager doesn't work

Hello,
I’ve wanted to use virt-manager with a custom built qemu in /usr/local/bin/...

I have installed kvm and qemu via the YaST2 Install VM applet, and it did work, then I built qemu and rebooted. Now virt-manager doesn’t work, because it drops me this error: No supervisor settings found for this connection (This was translated)
It also says, to check if kvm kernel module is running, and yes it is indeed running.
