Export for qemu usage outside docker?

[nreith]

I understand there is a need to manually save/export the docker container as an image, or save the container state in order to continue using docker-osx from where you left off without having to reinstall sonoma or whatever version that takes like 30 minutes, and not lose your work.

Does anyone know once this is all built inside the docker container, is there a way to export it, or copy certain files like the .img outside of the container, and then run those normally with qemu without the docker layer on top?

If that were possible, I imagine it would also be possible then to convert that vm .img to other formats and potentially run it directly in other hypervisors like hyper-v, vmware workstation, or virtualbox?

Thanks
