Two drivers from one package, both in the hypervisor role: - vmware_esxi talks to one host directly: facts, vmnics and vmkernel NICs, CDP/LLDP neighbours, sensors, VMs, datastores and port groups. - vmware_vcenter talks to a vCenter: every VM of every host it manages, with the host as the VM's node, plus distributed port groups. It reports no interfaces of its own; the hosts' NICs belong to the hosts. Both implement the HypervisorDriver VM contract: get_vms, get_vm_config, start/stop/reboot/suspend_vm and the four snapshot methods, and emit raw device warnings (maintenance mode, disconnected host, config issues, host managed by a vCenter, free license making the API read-only). Every read is a PropertyCollector query for the explicit paths in paths.py, converted by to_plain() into dicts and lists; the parsers only ever see that. tools/harvest.py dumps exactly those paths to JSON and tools/sanitize.py scrubs the dump, so a real host can become a test fixture without code changes. A VM's vmid is its instance UUID, which survives vMotion and re-registration; a MoRef does not. Tested against govmomi's vcsim in ESXi and vCenter mode, including real power and snapshot tasks. Not yet tested against real hardware.
