Gone Full Unikernel
Tell me if I&#x27;m missing something, but the premise of Unikernels seems to be that a ring-0 x86 hardware environment is the perfect fit for a universal container&#x2F;host interface.<p>Or to put it more charitably, since cloud compute services are based around booting VM images based on this model, we&#x27;ll just go with it instead of trying to use an abstraction that is actually designed for this.<p>Correct me if I&#x27;m wrong, but it seems to me that the first thing any unikernel is going to do when it boots is switch the (virtualized) CPU out of x86 Real Mode (which all x86 machines boot into for legacy reasons, but virtually no one has needed since circa 1995) into protected mode.<p>Is it just me or does this seem a little bit crazy?
