Pane boze ty to vidis… :-D Proc virtualizujes neco co ti muze bezet na tom jednom fyzickem HW a pripravujes se o zdroje systemu?
Virtualization is a toy sold as an enterprise solution. The argument
goes like this: you need a domain controller and sequel server so you
need 2 machines. So instead of paying for 2 machines you virtualize
them!!!!! OMGZOMG!!!!11111ONe
What Mr. dingle berry insultant forgets to point out is that both tasks
will run like ass in a virtualized environment AND can be easily
combined on the same box. Usually lost in the same conversation is
that you need both machines to be up at the same time too to be useful.
I have seen people virtualize a file server and domain controller on a
single machine. Which is awesome because now you get free >30% loss of
IO performance. You know it keeps bandwidth use lower and latency
higher. Exactly what lusers like.
Virtualization is great to develop kernel code and get an idea if it'd
work before moving on to real hardware (and fixing real bugs on real
hardware because virtualization failed to run right).
I like to play with old OS' as well so its neat for that but usually
doesn't work. This really is in the toy section though.
