I suppose work like this is demonstrating that, contrary to what e.g. the creators of Docker say, a virtual machine image is not too heavyweight to be our industry's equivalent of a shipping container. What is too heavyweight is a VM image of a conventional operating system distribution with all of the baggage that it brings. Would these fine-grained unikernels also run well on KVM, VMware ESXi, Hyper-V, or bhyve (FreeBSD's new VMM)? Or is Xen uniquely suited to this kind of thing?

I didn't realise that Docker/Container folks had ever said VMs were too heavyweight. Is this linked anywhere? > "Would these fine-grained unikernels also run well on KVM, VMware ESXi, Hyper-V, or bhyve (FreeBSD's new VMM)?" We've been asked this before and for KVM at least, it just boils down to someone suitably motivated to write the boot and VirtIO code [1, 2]. If anyone's interested in this, we'd love to hear about it [3]!

    Thanks. In hindsight that should have been an obvious place for me to look.
