(Years ago I had puppet and cobbler provisioning VMs over PXE and then iPXE. FWIU foreman is more actively maintained than cobbler, which is built on Django web framework.)

Vagrant manages VMs and virtual networks, in Ruby.

ansible-molecule creates, converges, and destroys VM(s) and containers, in order to test ansible playbooks and ansible roles in clean build roots.

podman machine manages VMs:

- podman-container-tools/podman-machine-os: machine image files: https://github.com/podman-container-tools/podman-machine-os/...

`podman kube play` over `podman machine` might solve for agents that need multiple VMs/containers

- Podman Desktop can work with the same local k8s setups as Docker Desktop. Though there's certainly more state to manage with k8s for agent session farm, k8s probably has better logging and quotas than a VM management script on each node.

OpenShift on OpenStack is one way to do containers over VMs over bare metal.

Microshift also does container-selinux.

There is not an apparmor policy set for containers?

bwrap and liboverlayfs and libseccomp are almost but not quite containers.

There are stronger container isolation layers that are more like a full or lightweight VM, that might be better for agent sessions: gVisor, firecracker vm, Todo

Cloudflare workerd is the open source part of cloudflare workers, which run lightweight WASM and JS VMs with multi-tenant isolation.

It takes far less resources to run a cloudflare worker than to run a container on cloudflare. So, if it's possible for an agent to operate within a WASM runtime ~container, that's probably more optimal for agent sessions.

Cloudflare/artifact-fs does lazy shallow git clones with a FUSE filesystem.
