What is the version you are using? In 2.0 by default it uses
qemu:///system url to talk to libvirt. If you are using 1.4 in the
configuration for kvm vmm, the file vmm_kvmrc it should be also
configured for qemu:///system, is that correct?
Also check that libvirtd is running as root, I suppose it is seeing
that the files are owned by root. This error usually happens when
virsh uses qemu:///session url to connect to it.
