Is there a real difference between having the virtual machines stored on a local qcow2 image in /var/lib/vz or in a LVM logical volume? How much LVM is faster than local images?

Hi,
that depends on your storage! The big advantage about an external lvm-storage is the possibility to use live-migration between several servers. If one server die, you can access the data from the lvm-storage. And of course, if your external lvm-storage raid die you lost all!
With shared storage you are much more flexible - you don't want to miss that (my opinion).
