I missed the reply all, here is the copy of our exchange.

Very good point, I will loo at it.

Indeed, I use iScsi already for other purpose :)

May be I misunderstood the concept of a snapshot, I thought it was the
ability from teh host to take an image of all the resource save it and
resume from that state later. In my case I would craft 'snapshoot'
with no 'device' setup as the going to be booted OS would redo the
devices discovery and init.

Hum, I looked a bit into this, downloaded the vbox src and loaded all
the debian packages as said in the man and the build failed, I guess I
got to learn a bit more about using the vbox API for implemented
things and later 'may be' expand vbox capabilities :)

Thanx for your sugestions.
Cheers,
Phi
