> A unikernel running on a hypervisor is a process, just with an awkward syscall interface and inflexible memory management. ...and with no way to run ancillary scripts and cronjobs e.g. log management, backups, security tools...

There's a reason why the usual famous tech companies don't use unikernels, generally speaking.
