A recent news article about a virtual-machine software pakage
<http://www.crn.com/nl/crndirect/showArticle.jhtml?articleId=54201647>
implied that both Intel and AMD are considering self-virtualizable
versions of the x86 architecture.
... the debut of virtualization features in next-generation CPUs
from Intel and AMD will make it easier to support unmodified
operating systems, ... [AFAIK, in such CPUs, all mode-sensitive
and/or location-sensitive x86 instructions would have to be made
privileged, i.e., to trap when executed in user mode.]
Does anybody know whether or when such CPUs might be expected to hit
the market?
Note: I realize that the article did not explicitly mention "x86
architectures", but various other architectures (e.g., the IA64) are
already self virtualizable, so the quote conveys a misimpression
unless it refers to x86-based instruction sets.
Thanks,
Tom Payne
