brief description  : These TM and VMM drivers allow the use of cLVM datastores on a pool of XEN hypervisors. It also brings high-availability and load-balancing to the hosted VM using the Clustered Xen Manager (CXM) stack.

== Description ==

The CXM drivers enable the management of an OpenNebula cloud based on a cxm cluster. 

The cxm cluster is a solution to host virtual machines on a pool of Xen hypervisors connected to a SAN. VM images are stored using LVM and cLVMd.

== Benefits ==

The use of a cxm cluster allows you to do live-migration, automatic failover and loadbalancing between Xen nodes.
These functionalities are handled directly by the cxm daemon, as close as possible from the hypervisors. Live-migration can be managed by the OpenNebula frontend.

== Documentation ==

The process of installing and configuring of a cxm cluster is described on project's page:
