Thank you! glad to be able to help ;)

As Itamar mentioned if you are running the spice client inside a VM
(dunno if this is case) you will need the guest paravirtual driver
and/or services for mouse handling. I have observed exactly this
behavior before when running the spice client in a VM when the guest
tools/drivers for mouse handling are not present (In my case most of
the time VirtualBox).

No this has been using virt-viewer on physical machines, and if you disable any secondary monitor, the problem goes away...which is a bummer, since many folks has more than one monitor these days. Also I have tried installing the qxl video driver and guest mouse handling add-on from the spice-space.org<http://spice-space.org> windows guest tools package, and that has solved this issue as well. But to use the video driver in Win7/2008(R2), you need to set windows to "Test Mode" because the driver isn´t digitally signed, and that disables it´s use in production, unfortunately. Which means that VDI with Windows guests in KVM, for now, is impossible. Correct me if I´m wrong.


Very amusing "bug":) But cripples SPICE´s usage.

I have tested this from 5 different physical machines running Win7/IE,
and this behavior shows itself only on machines with more than one
monitor, or a laptop with another monitor attached .e.g. These guest
tools you both mention, would these be
"http://spice-space.org/download/binaries/spice-guest-tools-0.1.exe"?
And can you install them in a physical machine as well?

cc-ing spice-devel to see if they have insights on your issue

       This is awesome work, thank you so much for this! For our
       users and
       administrators, having a button you just click to get a
       console is sooo
       much easier than having to copy-paste a bunch of cryptic
       addresses and
       passwords, and having to use the infamous, dangerous hacker
       tool VNC:)

       I followed the wiki instructions and a vital piece missing is
       to restart
       ovirt-engine before trying to install the spice-client from
       the install
       portal. I went back and read through the email you first
       posted and the
       restart was mentioned there so I did and then it worked!
       Wohoo! So you
       might want to add that point to the wiki page as well, to
       avoid future
       confusion.

       But...when I have virt-viewer(-0.5.3) installed, log in to
       webadmin and
       click for console on a guest, the console shows up. But when I
       try to go
       into the console window with the mouse cursor, the cursor
       jumps off to
       one of the edges of my *monitor*, and not into the console
       window- as

       you would expect. Maybe virt-viewer mistakenly "thinks" that
       the edges
       of it´s window really are the edges of the whole monitor? Am I
       holding
       it wrong?


   do you have spice guest side drivers for local mouse handling?

                   I have requested a wiki account so I will just
               need someone to
                   grant the proper create/edit page access or create
               a stub page
                   and allow edit access to it.

                   ------------------------------__------------------------------__------------



                               I have seen this question asked many
                   times on this list
                               and the spice-devel list. Now having
                   figured out how to
                               make it work I will provide the answer
                   to the rest of
                               the community.

                               *NOTE* this only applies to
                   Windows/Internet Explorer
                               users. There exists no other option
                   other than the html5
                               spice console (still beta/in
                   development) for windows
                               users ATM. This will also only work
                   with Internet Explorer.

                               Basic Steps:
                               - Install an oVirt server.
                               - Add at least one node
                               - Setup storage/iso/export domains

                               Advanced steps
                               - Start by downloading:
                   http://elmarco.fedorapeople.__org/spice.cab
                   <http://elmarco.fedorapeople.org/spice.cab>
                               - Create a directory for it oVirt
                   looks by default in
                               /usr/share/spice
                               - Rename spice.cab to SpiceX.cab and
                   copy it into
                               /usr/share/spice
                               - Now edit

                   /usr/share/ovirt-engine/__engine.ear/root.war/WEB-INF
                   and
                               add the following:

                                <!-- SpiceX.cab -->
                                 <servlet>

                   <servlet-name>SpiceX.cab</__servlet-name>


                   <servlet-class>org.ovirt.__engine.core.FileServlet</__servlet-class>
                                   <init-param>
                                     <param-name>type</param-name>

                   <param-value>application/__octet-stream</param-value>
                                   </init-param>
                                   <init-param>
                                     <param-name>file</param-name>

                   <param-value>/usr/share/spice/__SpiceX.cab</param-value>
                                   </init-param>
                                 </servlet>
                                 <servlet-mapping>

                   <servlet-name>SpiceX.cab</__servlet-name>

                   <url-pattern>/spice/SpiceX.__cab</url-pattern>
                                 </servlet-mapping>

                               - Next create an html file within

                   /usr/share/ovirt-engine/__engine.ear/root.war
                               - In the example below an html file
                   called "spice.html"
                               - Copy/Paste the below into spice.html:

                               <!DOCTYPE html>
                               <html>
                               <head>
                               <title>SPICE Plugin Installer</title>

                               <script type="text/javascript">
                               function installSpice()
                               {
                               try {

                   document.getElementById('__SpiceX').innerHTML =
                               '<OBJECT id="SpiceX"
                   codebase="/spice/SpiceX.cab"

                   classid="clsid:ACD6D89C-938D-__49B4-8E81-DDBD13F4B48A"
                               width="0" height="0"></OBJECT>';
                                   } catch (ex) {
                                       alert("Epic Fail!: " +
                   ex.Description);
                                   }
                               }
                               </script>

                               </head>
                               <body>
                                   <p>
                                   <p><b id='SpiceX'>Spice ActiveX
                   Plugin</b> </p>
                                   <button
                   onclick='installSpice()'>__Install Spice
                               Plugin</button>
                                   </p>
                               </body>
                               </html>

                               - Save the file
                               - You will now need to restart the
                   ovirt-engine service
                               EG: systemctl restart
                   ovirt-engine.service OR service
                               ovirt-engine restart
                               - The installer page will now be
                   available at
                               http://<url to ovirt
                   server>/spice.html EX:
                   http://ovirt.azeroth.net/__spice.html
                   <http://ovirt.azeroth.net/spice.html>
                               - Navigate to that page and click the
                   install button
                               - IE will prompt you to deploy/install
                   the SpiceX
                               cabinet file
                               - It may gripe about an unsigned or
                   untrusted source,
                               acknowledge this an proceed anyways
                               - If the install succeeds the text
                   "Spice ActiveX
                               Plugin" on the page will change to
                   blank (it's actually
                               the plugin with null values)
                               - The console button in the user and
                   webadmin portals
                               will now launch the new virt-viwer
                   spice based console!

                               Happy Spice Consoling to your VM's
                   from Windows!

                               *NOTE*
                               To uninstall the plugin:
                               - The below removes the add-on from IE
                   (EG: removes
                               knowledge of "application/x-spice")
                               - pop a command terminal and type:
                               On Windows XP: regsvr32 /u
                   "C:\Documents and
                               Settings\Administrator\Local
                   Settings\Application
                               Data\virt-viewer\bin\SpiceX.__dll"
                               On Windows 7 regsvr32 /u C:\Documents and
                               Settings\Administrator\Local

                   Settings\AppData\virt-viewer\__bin\SpiceX.dll"
                               - Next we need to remove the rest of
                   virt-viewer
                               - Go to add/remove programs and
                   uninstall virt-viewer,
                               this removes the rest of virt-viewer
                   from the system
