Is it true that there is a central file system accessible to both hosts and that all that is transferred is the current MEMORY contents of the domain? That is the basic idea yes. If this is true, is there no way to physically transfer the domain file system from one host to another? Thanks. In theory this could be done, but would require a lot more overhead. I can't recall if there is any work with Xen on this or not. I believe OpenVZ, which virtualizes at a layer higher (the operating system), has support for live migration without the central file system. Regards, Todd
