[PetiteCloud] CFT: bhyve AMD snapshot

Could one of the bhyve people please forward the thread to the FreeBSD
-virtualization@ mailing list?

It's clearly (to any sane person) on-topic there, but I literally have a
phobia about posting there because god knows what Michael Dexter will
decide is on-topic and what is not... btw are you aware of the following
statement on his company site [which he hides well]? "Our developers have
produced original virtualization technologies and our administrators have
operated and automated Unix systems since long before they were rebadged
the "Cloud"." (http://gainframe.com/support/).. In short he is *NOT*
unbiased in the question of whether cloud computing is relevant for
-virtualization@ or not [note to Mike Dexter before flaming: this is not
being posted to  *ANY* freebsd list, and if you have something to say, say
it to *ALL* the people on the to line [I will forward your answer if it is
not]

A general question for Mike Dexter: why would a NAS maker be so fearful of
cloud computing but like virtualization?   The only reason we can think of
is you somehow think you will sell less equipment if everything is
clouds... if this is your impression then you have a *VERY* dated idea of
what cloud computing is and what it is not (Most likely, small private
clouds of the kind PetiteCloud is targeting would enable you to sell MORE
of your type of NAS because most of what you sell it too large for most
non-data center uses and too small for most data center uses.)
