proxmox-ve driver development

[lnxbil]

Hi, I'm the author of the docker machine proxmox-ve driver and I'm struggling with the best OS to run inside of the VM, which directly corresponds to the actual integration. On one hand, we would need to have a working extrinsic parameter set like qemu with defined network, users and such (or use cloudinit) and on the other side the intrinsic configuration via qemu-guest-agent that configures and detects as we move along. The possibilities are just endless for this and overcomplicates the driver development.

I have a working version with a self-built boot2docker image with qemu-guest-agent integration and also with a self-build RancherOS image. It's hard to believe that one should have special images for this, so what are your choices for running this in production?
