[libvirt-users] Difficulty with a transferred VM

I have a better faster server and moved the disk from the old one to the new one. After the move, I edited the xml file manually to give it the correct paths for the new machine, since the mount point for all the VM storage pools is now different. I get # virsh start www.foo.org error: Failed to start domain www.foo.org error: internal error cannot load AppArmor profile 'libvirt-xxx .... xxx' I tried aa-complain /usr/sbin/libvirtd I even tried editing /etc/apparmor/usr.lib.libvirt.virt-aa-helper and adding the new path to where the VM images are stored. Still no joy. Suggestions?
