Abstract
A method, system and program product for enabling migration of Virtual Machines with concurrent access to data across two geographically disperse sites to enable load balancing across the two geographically disperse sites, by presenting over a network a read writable logical volume at a first site, presenting over a network a read writable logical volume at a second geographically disparate site; wherein the first volume and the second volume are configured to contain the same information, and enabling read write access to the volume at the first site or the volume at the second site for a first virtual machine while keeping the data consistent between the two sites to enable transparent migration of the virtual machine to load balancing across the two sites according to at least one load balancing metric.
