One of the things that seems to really fall flat is the claim claim that the security is bad for unikernels.  The comparison point though is not a traditional OS running in a hypervisor but a container running on the host OS.  In that comparison I think unikernels are emphatically more secure than what you get on Linux, and have essentially all of the same advantages of containers (plus a few extra ones).<p>For Joyent of course they have a book to talk up and they want to sell you their own solution which looks more like containers than a hypervisor.  The Joyent solution is I think undoubtedly very interesting and well-considered but I have a suspicion that they&#x27;ve hitched their wagon to the wrong horse and Linux will keep winning.
