Container images (like in Docker) contain an OS? That's news to me. I thought they avoided having an OS, and instead just have binaries that are run in a very isolated environment.
It sounds like unikernels are still based around hardware virtualization. That seems like a mistake to me. If your image includes the code to switch an x86 processor from real mode into protected mode, you're doing it wrong (IMO).
- wakwanza 11y agoWould depend on the choice of unikernel and how theyr doing their stuff osv.io for example basically run the app in kernel space on top of a hypervisor and inherently as hardware agnostic as possible.
- bjt 11y agoContainer images don't have a kernel, but they do have userland portions of an OS (e.g. libc).
- cpeterso 11y agoWon't each unikernel image running on a hyper visor also include redundant copies of libraries like libc?
- rumcajz 11y agoAFAIU the whole thing runs in ring 0.
