[Openstack] No mouse control for a Windows 7 instance

Hi Thiago.
I think I may have figured out some more pieces to the puzzle regarding the
inconsistent results I mentioned earlier. For the most part I've been using
the dashboard to create/launch/terminate images. There is a directory on
each compute node /var/lib/nova/instances/ which seems to contain copies of
images that have been launched to it as well as other files related to
them. I think what happened is I had launched a Windows image to my compute
node and saw that the pointer wasn't working. I then enabled use_usb_tablet
in /etc/nova/nova.conf . I may have terminated the previously launched
image using the dashboard (not totally sure if I did this) and then
rebooted the compute node. At this point the mouse still didn't not work.
However, I noticed that when launching the image this time it booted very
fast compared to when I did it the first time. I looked
in /var/lib/nova/instances/_base and discovered a copy of the image that
had been created earlier in the day. In my next test I shutdown/terminated
the instance from the dashboard but this time I deleted all files related
to it in /var/lib/nova/instances/_base. I then launched a new copy of the
Windows 7 image. This time it took a lot longer to complete because it was
once again creating a local copy on the compute node. Once it was up and
running I opened the console and my mouse was now working. Although a
couple of times it started working and then would suddenly stop (this seems
like a definite bug). Also, when terminating/removing an image from the
dashboard I would think the local copies of it on compute nodes should be
deleted too. Not sure if it's a bug or by design that they are not.
Anyways... you may want to try deleting the files
in /var/lib/nova/instances/ and re-launch your Windows image to see if it
solves the issue for you.

Hi Thiago.
Since the last e-mail I sent you I have been doing some more testing.
Although I've had some inconsistent results, I does seem to work for me
when put into the [libvirt] group in nova.conf. I thought it was strange
that it didn't work at first since I don't think it should matter where
it's located in the config file. I'm not quite sure why it didn't work when
I first tried.
Good luck,
Ernie

Hi Ernest,
Thank you for your time!
This option isn't working on IceHouse with Ubuntu... I tried it under
[DEFAULT] at nova.conf, nova-compute.conf, under [libvirt], didn't
worked...
I'll fill a bug about this...
Best!

Hi Thiago.
I'm installing on RedHat but I would think the configuration would be
pretty much the same. However, RedHat uses /etc/nova/nova.conf
not /etc/nova/nova-compute.conf. According to the install guide I have
for Ubuntu that is the file you should be using as well. I wonder if that
is part of your problem.
The other part is that putting "use_usb_tablet=true" in the [libvirt]
group doesn't seem to have any effect (at least not on RedHat). Just like
on Ubuntu, the [libvirt] group is the default location for that option on
RedHat. Since most other options during nova configuration on RedHat were
added to the "[DEFAULT]" group I decided to try putting it there. On
RedHat, the [DEFAULT] group can be found at the top
of /etc/nova/nova.conf. Putting it there solved it for me.
Hope this helps,
Ernie

Ernest,
Where did you put your "use_usb_tablet=true" config option?!
The doc
http://docs.openstack.org/icehouse/config-reference/content/nova-conf-changes-icehouse.html
recommends under [libvirt] group...
I'm using Ubuntu 14.04 + IceHouse and I configured this option within the
file "/etc/nova/nova-compute.conf" with at:
--
[libvirt]
use_usb_tablet=true
--
But, it have no effect.
I'm seeing the following line at the logs:
--
nova-compute.log:2014-07-21 20:53:42.782 7435 DEBUG
nova.openstack.common.service [-] libvirt.use_usb_tablet = True
log_opt_values /usr/lib/python2.7/dist-packages/oslo/config/cfg.py:1949
--
But the Instance's XML have no "tablet" entry. I checked it via both logs
and using "virsh dumpxml instance-xxxxxxxx"...
What am I missing?
I really appreciate any help! Tks!
BTW, I'm using SPICE Consoles...
Cheers!

Hi.
After taking one more look at nova.conf I figured out the issue. I
had followed the instructions in OpenStack Installation Guide for
Red Hat Enterprise Linux, CentOS, and Fedora to install/configure
everything. With this method the configuration settings for
services get stored in the "[DEFAULT]" section at the top of the
various .conf files. Moving the use_usb_tablet=true line into this
section fixed the problem.
This brings me to another question though... Is there a way to set
the console so only the VM's pointer is present? Other console
clients have this feature and usually a function key is hit to exit
that mode and get the local systems pointer back.
Thanks,
Ernie

Subject: No mouse control for a Windows 7 instance
Hi.
I setup a small test/development environment to get familiar with
setting up an OpenStack environment. It consists of 1 network, 1
controller, and 1 compute node. Within it I imported/launched the
Cirros test image, a Redhat 6.5 install iso image, and a Windows 7
qcow2 image (the KVM I run on my RedHat laptop) . Everything seems
to work fine except accessing the Windows 7 console. After
initiating a console connection via "nova get-vnc-console Windows7
novnc" I'm able to connect to it from Firefox but I don't have any
control of the VM's mouse. When doing the same with the RedHat 6.5
image the VM's mouse moves along with my laptop's mouse. I did find
the following in /etc/nova/nova.conf but enabling it and restarting
the compute node had no effect.
# Sync virtual and real mouse cursors in Windows VMs (boolean
# value)
#use_usb_tablet=true
Can someone tell me how to get the mouse working for a Windows VM?
Thanks,
Ernie
