# 1. ENV[PROXMOX_URL] exists: talk to an actual Proxmox server and record HTTP
#    traffic in VCRs at "spec/debug" (credentials are read from the conventional
#    environment variables: PROXMOX_URL, PROXMOX_USERNAME, PROXMOX_PASSWORD)
# 2. otherwise (Travis, etc): use VCRs at "spec/fixtures/proxmox/#{service}"
