These things are a great idea but it turns out they're always a massive pain to actually use. Until container-as-VM is as easy to get as installing docker, not really viable for mainstream use imho.
Someone else mentioned about kata and it seems to be pretty interesting imo.
What are your thoughts on it?
First time I hear about the "Cloud Hypervisor" https://www.cloudhypervisor.org/. It's really hard to keep up with all new stuff in the field.
Cloud Hypervisor has been around for years. It's a very similar Rust codebase to Firecracker (and shares libraries). People use it because it supports PCI passthrough.
