   7 # Expectations:
   8 #   1) libvirtd installed and running
   9 #     - typically from libvirt package
  10 #   2) libvirt Python API available
  11 #     - typically from libvirt-python
  12 #   3) optionally one or more VMs up
  13 #   4) libvirt.hv.* metrics always expected
  14 #   5) with VMs available at least:
  15 #     - libvirt.dominfo.uuid
  16 #     - libvirt.dominfo.name
  17 #     - libvirt.dominfo.memory.{boot,current}
  18 #     - libvirt.dominfo.vcpu.*
  19 #     - libvirt.dominfo.type
  20 #     - libvirt.dominfo.os.type
  21 #     - libvirt.domstats.mem.*
