I think many people (including unikernel proponents themselves) vastly underestimate the amount of work that goes into writing an operating system that can run lots of existing prod workloads.

There is a reason why Linux is over 30 years old and basically owns the server market.

As you note, since it's not really a large existing market you basically have to bootstrap it which makes it that much harder.

We (nanovms.com) are lucky enough to have enough customers that have helped push things forward.

For the record I don't know of any of our customers or users that are using them for HFT purposes - something like 99% of our crowd is on public cloud with plain old webapp servers.
