[one-users] Local storage on the node (lvm, etc)

Hello,

As far as I understand the documentation, it looks like all storage options
for OpenNebula are shared - ceph, iSCSI, nfs, cLVM.

However, configuring the storage locally on the node would allow for better
performance (especially if using SSDs), even though the VM then would not
be fault tolerant (node goes down, so does the storage for the VM). On the
other hand it would still be possible to migrate the VM, assuming the
original node is up (by copying the data to the new node).

Is there a way to configure OpenNebula to use local logical volumes as a
datastore? Create the lv on the node, boot the VM, if nned be create the lv
on another node, migrate the VM.
