Fedora :: KVM Could Not Open Disk Image - Permission Denied

I'm getting error from KVM when i try to create new machine. I have install group Virtualization. From gui virtual-manager (after being asked for root passwd) tried to create new machine. When pressed on 'Finish' got this 'Permission denied' error:
Code:

It's running as a root, what permissions we are talking about here? I'm running F14, kernel 2.6.35.10-72.fc14.x86_64, libvirtd 0.8.3
