# PCP QA Test No. 1041
# Exercise the libvirt PMDA - install, remove and values.
#
# Copyright (c) 2016 Red Hat.
#
# Expectations:
# 1) libvirtd installed and running
# - typically from libvirt package
# 2) libvirt Python API available
# - typically from libvirt-python
# 3) optionally one or more VMs up
# 4) libvirt.hv.* metrics always expected
# 5) with VMs available at least:
# - libvirt.dominfo.uuid
# - libvirt.dominfo.name
# - libvirt.dominfo.memory.{boot,current}
# - libvirt.dominfo.vcpu.*
# - libvirt.dominfo.type
# - libvirt.dominfo.os.type
# - libvirt.domstats.mem.*
