can lkl based app run on vm

[qsmen]

Hi,
unikernel (App based on libos) can run on a VM without os. Can the app based on lkl run on vm without os too? if not, I choose to compile the app in its targeted enviroment. i.e, if it runs in linux , i compile it in linux.
I want to use lkl to compile a single address space app.
Thank you.

It runs on linux and some other platforms(mainly linux)

I see. Thank you.
It is said that "LKL can run in any environment, as long as the environment provides a few basic primitives" in the paper lkl. My questions are:
1).what are the few primitives? just the io syscalls supported by VMM?
2). If so, a VMM already implemented the few primitives, can the lkl-based app run in a VM?
3).and is the linked lkl-based app similar to the concept of unikernel? That is, the app is selfcontained except io syscall.

I don't know much about 1) and 2). However, lkl is like a unikernel, but nearly all its syscall is selfcontained(However, host syscall can be called indirectly.

there is my previous attempt to integrate LKL as a unikernel. ukontainer is a collection of repositories with running application linked with LKL over container runtime. It uses rump hypercall, which interfaces various underlying environment including VMMs (e.g., QEMU, xen), though the ukontainer hasn't implemented so far.

So technically the answer should be, Yes, but not ready yet as far as I'm aware of.

See more detail in my past documents and repositories.
