It really depends on what 'kernel-minimal' is. If it's the
same kernel (identical vmlinuz) with groups of modules, then I'm
assuming this is the same as what everyone else is proposing.
But more dangerous if this is a recompile of the kernel (maybe same
source, different configs). Then inevitably we're testing different

LXC isn't a secure alternative to full virtualization -- try poking
random /sys files on your container -- and even now OpenVZ isn't quite
upstream. Also clouds are existing ecosystems. For example I can't
call up Amazon and ask that they reimplement their service on top of
LXC instead of Xen.

Well, no. I don't colocate with everyone who might want to download a
