I can give a more detailed description tomorrow if needed, but in general the feature has not changed since it was introduced in 3.0. It was pulled due to licensing and I added the functionality back, so people upgrading will see no difference.
The CLVM feature for KVM allows for root and data disks (primary storage) to reside on Linux logical volumes. Administrators are required to manage/configure the CLVM on the KVM hosts independent of cloudstack. Once the volume groups are available, an administrator simply adds primary storage of type CLVM, providing the volume group name. Then cloudstack will create and manage logical volumes as needed. Snapshots are also supported. Cloudstack will create an LVM snapshot, copy off the applicable logical volume to secondary storage in qcow2 format, and then delete the LVM snapshot.
