[one-users] Questions on shared_lvm setup

In building out a fresh OpenNebula cluster, I came across
http://wiki.opennebula.org/shared_lvm which I thought was an excellent
choice for my particular setup, especially not having to fight cman/clvmd
oddities.  The post, though very good, still left me with some questions in
the how-to range; likely to do with my not knowing OpenNebula internals
very well.

That being said, I do have some questions regarding the setup for it on a
4.4 install (CentOS):

1) The lvm.tar.gz and livemigration.tar.gz files contain lvm/ and shared/
directories, but the instructions talk about putting these files in the
remote/datastores/shared_lvm and remote/tm/shared_lvm directories.  How
exactly should those files be installed into them?

2) Using sunstone to configure the datastores, I figured I would need to
use the Custom method, but I don't have any idea how to point that
datastore to a particular VM.

Any help on this would be appreciative.

Thanks
