The first feature is an updated and hardened ability that allows administrators to make snapshots and clones of running virtual machines. With snapshots, RHEV can save a copy of the running virtual machine for record-keeping purposes. These snapshots can now be created without first having to stop the virtual machine, thus maintaining environment uptime. With cloning, RHEV can now make a copy of a running virtual machine, or it can create a virual machine from a snapshot. This allows users to create copies of the state of a virtual machine at the moment the snapshot was taken. This is particularly valuable in software development environments where frequent testing takes place.
The second feature, live storage migration, may be most important addition in the new release in spite of the fact that it is currently being offered as a tech preview. Live storage migration was a huge feather in VMware's cap when it introduced the technology into vSphere. It quickly became an enterprise checklist item that customers have come to expect in a server virtualization platform.
With live storage migration, users can dynamically migrate VM storage across different storage arrays without first shutting down the virtual machine(s) in question. Red Hat notes that its live storage migration will work better once it updates the underlying Red Hat Enterprise Linux (RHEL) platform on which RHEV runs. The full availability of the live storage migration feature will likely appear in a RHEV 3.1.1 update sometime early next year.
