I've been tinkering with this problem but I can not find the a clear candidate for the problems you are facing. You have to take into account that VM_DIR is only used for the remote nodes, in the frontend images for running vm's are always stored in $ONE_LOCATION/var or /var/one/lib. Could you try exporting that dir into the nodes in the same path (a symlink can be used) and stop using VM_DIR parameter in the conf file?. If that configuration work we can begin changing VM_DIR and other stuff to suit your needs.
