alt Hacker NewsI think that part of it is that relatively few people use bare-metal servers these days, and nested virtualisation isn't universally supported. I also found this technical critique [0] compelling, but I have no idea if any of it is accurate or not.

there is a workaround for nested virt requirements.
you can use PVM patch and para-virtualization. I've seen several startup using that approach to be able to create VM on small/cheap EC2 instances.
When I first heard about unikernels my hope/thought was that people would go back to using more bare-metal servers for unikernels.
