Red Hat RHEV gets storage savvy

Storage live migration can be useful for several areas, Dubuque said. Live storage migration can be useful for balancing I/O across a system, or for those cases when a pool of VMs need to move from one SAN to another. In previous versions of the RHEV, such migrations would require the live running VM to be shut down while its disk image was being relocated. The live migration technology is available as a technology preview, until the release of the next version of Red Hat’s flagship RHEL (Red Hat Enterprise Linux), which will provide the last bit of the needed functionality to fully execute live migrations.
