Title:
Can't set "pointer_model = None" in nova.conf
Status in OpenStack Compute (nova):
Fix Released
Status in oslo.config:
Won't Fix
Bug description:
Description
===========
nova.conf includes option pointer_model. The help text in the config
has 2 "possible values" sections (copied below) specifying either
"None" or "<None>" as correct values. Neither of these is accepted by
Nova. Here are the error messages from nova-compute.log:
2020-03-03 11:05:17.233 228915 ERROR nova ConfigFileValueError: Value
for option pointer_model is not valid: Valid values are [None,
ps2mouse, usbtablet], but found '<None>'
2020-03-03 11:06:24.761 229290 ERROR nova ConfigFileValueError: Value
for option pointer_model is not valid: Valid values are [None,
ps2mouse, usbtablet], but found 'None'
#
# Generic property to specify the pointer type.
#
# Input devices allow interaction with a graphical framebuffer. For
# example to provide a graphic tablet for absolute cursor movement.
#
# If set, the 'hw_pointer_model' image property takes precedence over
# this configuration option.
#
# Possible values:
#
# * None: Uses default behavior provided by drivers (mouse on PS2 for
# libvirt x86)
# * ps2mouse: Uses relative movement. Mouse connected by PS2
# * usbtablet: Uses absolute movement. Tablet connect by USB
#
# Related options:
#
# * usbtablet must be configured with VNC enabled or SPICE enabled and SPICE
# agent disabled. When used with libvirt the instance mode should be
# configured as HVM.
# (string value)
# Possible values:
# <None> - <No description provided>
# ps2mouse - <No description provided>
# usbtablet - <No description provided>
#pointer_model = usbtablet
Steps to reproduce
==================
On an openstack hypervisor:
1. Edit nova.conf and change line "#pointer_model = usbtablet" to either
"pointer_model = None" or "pointer_model = <None>"
2. Restart nova-compute service
3. Tail nova-compute.log
Expected result
===============
Nova runs without errors and does not load the USB driver.
Actual result
=============
Nova throws the error described above.
