It's dawned on me that there still is the single
point of failure with all virtualization of a computer and that is the single
system that is being virtualized. Be that system an Intel/AMD system, a power PC
system, or even a mainframe(FYI Xen is very similar to ZVM which has been around
with different names for over 40 years). I'm submitting the idea to build the
virtual system off of a grid of computers. The obvious hurdles would be
non-existent processor and memory drivers for this, as well as a means of
controlling the allocation of resources to the guest. The disk system of the
virtual system could be iSCSI disks and local to that system only. The obvious
system gains are no single point of failure with the grid, the potential to
fully utilize every distributed system in an environment, and the licensing cost
of one virtual processor which is actually over 1000 procs. I'd like to have the
Xen Community set the standards for this idea here.
