# Precedence is the following (lowest priority first):

# 1) if run as root, 'uri_default' from /etc/libvirtd/libvirt.conf,
#    otherwise qemu:///session.  There is no way to mock this file for
#    virsh/libvirt.so and the user may have set anything in there that
#    would spoil the test, so we don't test this
#
# 2) 'uri_default' from $XDG_CONFIG_HOME/libvirt/libvirt.conf
#
# 3) LIBVIRT_DEFAULT_URI
#
# 4) VIRSH_DEFAULT_CONNECT_URI
#
# 5) parameter -c (--connect)
