Re: [coLinux-devel] VM everywhere

[Digital I. Inc. <ok...@di...>]

It is easy.

If your PC is idle,
You download VM from a file server, resume it on your PC (Linux/Win, both),
then back your VM suspending image to a file server.

But I think coLinux is not so suited for this purpose.
because, it runs on ring0.
if a VM you downloaded has virus or such, your PC gets virus.
I dont want to take such a risk. do you want?
Maybe a pair of UML/UMLWin32 is better.

What you mentioned is a kind of grid computing.
And another big issue for it is, what you use it for?
I think only market for such a technology is
scientific area, in short, number crunching.
You know any other usage?
