Apologies after replying to my own post. After applying the latest 
update of kvm, libvirt etc from Daniel Baumann (dnjl)'s PPA (the one I 
had been previously using), I noticed a change was related to giving 
more permission to libvirt relating to access to disk storage when 
apparmor is running.

With this update 0.8.1-2ubuntu1.1~dnjl1~lucid0, snapshots are fine again 
now. I can create/delete whilst guest is running or shutdown

Kind regards
