Whilst researching my AMD CPU comparison post I found these useful AMD virtualisation resources. I think that they will be helpful in changing opinions that have been form previously about virtualisation as a enterprise solution.

VIRTUALIZING SERVER WORKLOADS
LOOKING BEYOND CURRENT ASSUMPTIONS
"And while virtualization has moved out of its traditional domain into mainstream production, conventional thinking about its capabilities and limitations still keeps many organizations from embarking on large implementations. The suitability of workloads for virtualization in production environments is often guided by assumptions that are no longer true. Because every server workload has distinct performance characteristics, understanding and taking those characteristics into consideration is necessary to determine the server’s suitability for virtualization.
Improvements in virtualization hardware and other advances in virtualization technology are making it possible to virtualize an increasingly wide range of
workloads.
In summary, organizations that decided against virtualization in the past because of concerns about CPU, memory, or I/O bottlenecks would do well to take
another look.
