+# Override the maximum number of opened files.
+# This only works with traditional init scripts. In systemd world, the limit
+# can only be changed by overriding LimitNOFILE for libvirtd.service. To do
+# that, just create a *.conf file in /etc/systemd/system/libvirtd.service.d/
+# (for example /etc/systemd/system/libvirtd.service.d/openfiles.conf) and
+# write the following two lines in it:
+#   [Service]
+#   LimitNOFILE=2048
+#
 #LIBVIRTD_NOFILES_LIMIT=2048
