Back in July 2006, one of the most contentious issues at the Linux Kernel
Summit was what to do about virtualization. At that time, there were three
contenders: Xen, VMware, and OpenVZ (the latter being a lighter-weight
container-based approach). The biggest fight was between Xen and VMware over
competing approaches to running kernel operations through their respective
hypervisors: Xen touting their hypercall interface and VMware touting their
VMI (Virtual Machine Interface) approach. Neither of these approaches was
palatable to kernel developers for a variety of reasons, most of which were
technical but also because selecting either would give that contender a great
public relations boost over their competitor.
The reason for the fuss? Virtualization schemes like Xen and VMware can be
programmed to work correctly on unmodified operating systems. However, they
do t... (more)
The computing industry goes in cycles. The latest trend, growing in buzz over
the past year, is server consolidation aided by virtualization software.
Virtualization software for a computer allows a single machine to behave as
though it were many different, separate computing systems; each virtualized
instance behaves almost identically to an independent physical machine. Using
virtualization software, a roomful of servers can be consolidated onto a
single physical box (provided it's powerful enough). Pundits claim this trend
is cyclical because it's returning us to the old days ... (more)
