The problem with VMI is that while it allows hypervisor side evolution
it doesn't really allow Linux side evolution with its fixed spec.
But having it a bit isolated is probably ok.
actually, wouldn't something like this allow for a one-way evolution (the spec
can be changed, but the hypervisor side needs to support clients what only talk
older versions. i.e. the new spec is a superset of the old one (barring major
security-type problems that require exeptions to the rules))?
