Hyper V Mouse Cursor is Dot
Hyper-V RC0 installed on host AND guest.
x64 2008 Host
x64 2008 Guest
The mouse cursor is always the dot that usually represents an uncaptured mouse. The mouse is properly captured and integrated, though. That is, I have all of the features of integrated mouse, except the cursor is not right.
Ideas?

Were some of the updates applied between the time that you applied KB949219 to the VM and the time that the mouse cursor disappeared?

I'm guessing you don't have the ICs properly installed in your VM. For 2k8 VMs running against Hyper-V RC0, you need to install the RC0 QFE in the VM.
Verify you've done that and see a "VMBus HID Miniport" device in your device tree.
Thanks,
ChrisDouble checked that and "Microsoft VMBus HID Miniport" is installed under "Human Interface Devices" and is reported as working properly. The RC0 hotfix was installed. All aspects of mouse integration work properly, just the cursor is incorrect.
One thing I failed to mention: This is something that happened a few days after the VM guest OS was installed. It worked correctly for some time.
In that time between the time that you installed the guest and when the cursor disappeared, did any security updates get pushed to the system via WU?
Yes, all availible updates for windows 2008 x64 have been installed. If you need a complete list of those let me know.

Hello Mike.
I've got the same issue here, and I found out that one (or a combination) of these updates is to blame:
KB941693, KB949189, KB890830, KB948590, KB946609, KB948881, KB947864
Hope this helps,
Jeroen.
- Apparently this problem is solved in Hyper-V RC1.

- Not in our case. We are running RC1 and our cursors in all guest OSes are currently a dot/square.
We have multiple guest OSes running on our host. The cursor problem occurred at different times. At first the cursor was stuck to what was currently active. Rebooting the guest OS changed the cursor to a dot. Rebooting the server seems to resolve the issue but only temporarily. - Hi altogether,
I' got the same problem, too: After re-booting the host machine (W2K8E x64), the mouse cursor of the guest machine (WXPProSP3 x32) gets back from a dot to a normal arrow... and... after a while - i don't know the real circumstances - it falls back to a dot.
And the dot cursor is sometimes really hard to find on the guest desktop!!!
Thaught this issue would disappear with KB95050... but... nothing happened...
Any new ideas ???
DJB - I'm having exactly the same mouse cursor problem of the guest machine (Win2K3SP2). Initially the mouse cursor was a dot but then later it turned to hourglass.
I'm running the latest hyper-v (Windows6.0-KB950050) on Win2K8E. A reboot of the host machine will fix the cursor problem but it will come back sooner or later.

- Likewise...
RJ - I have the same problem.
And it just appears the cursor gets "stuck" in some state. Sometimes, it the dot. Other times, it's a circle shape.
Anybody solve this? - Ditto:
- After a restart of the Guest OS, all is fine
- After a "period of time" (usually under 2 hours) of active interactive usage of the guest, the bug occurs
=> cursor turns into "whatever" cursor is active at the time: a frozen animated cursor, a "up down arrows" cursor, a "dot" cursor, ...
My configuration:
- Running HyperV "Release" version with Host OS "fully patched".
- Guest OS in my case is XP-SP2 (not fully patched...).
HINTs:
1) I *have* switched (via Control Panel, Mouse, Pointers) the cursor scheme to a different from the default (in the Guest).
2) Changing the scheme *after* the bug occurs has no effect whatsoever...
Christian De. - How many CPU's do you have assigned to the XP SP2 VM?
I had this issue with RC1 of Hyper-V using Multiple CPU's on an XP SP2 VM and I have not seen it since as long as I follow the "Supported OS" list & CPU configurations as I could never quite 'nail down' the exact cause, I have not seen it for months now.

I'm running a supported guest os (Windows Vista Ultimate x64 Edition with Service Pack 1) and get the mouse cursor stuck issue. - Brian Bilbro said:I'm running a supported guest os (Windows Vista Ultimate x64 Edition with Service Pack 1) and get the mouse cursor stuck issue.Have you tried re-installing the "Integration Components" to see if something has gone weird with the mouse driver?
Cheers, Stephen Edgar - Still no solution?
I have Windows Server 2008 std 64bit as a host, then 2 X Windows Server 2008 std 64bit, both as guests.
Having the same issue in both of the guest machines.
All updates have been applied, 1CPU each, 2GB memory each, one of the guest machines has desktop experience feature installed. Two other machines do not.
Oh... I am having the same issue with the new machine that I've just created 5 mins ago. Windows Server is being installed on that machine and the mouse pointer is "dot"
I'm using the release version and all fully patched.
This is really an annoying issue. Please help.- Bearbeitetzjhkim Donnerstag, 16. Oktober 2008 09:03
- I have the same issue. Any solution?
- Same here. I wasn't really doing anything, no updates have been applied since earlier today, and all of a sudden the mouse cursor appears as a dot. Rebooting doesn't help.
- Has there been any new information on this problem? I am also seeing this and it is very frustrating. The issue seems to come and go, with no clear-cut delineation for when it happens.
I am running a Win2008 32-bit Standard guest on a 2008 64-bit Core host. We've got the same thing...sometimes it's a small square (no rendering, just the marker) and sometimes it's a random cursor- vertical resize, etc.
2008 Standard x64 Core RTM
Any updates??
- We are experiencing the same problem here. It is happening with guests with all different OSs. Win XP x86, Server 2003 R2 x86, and Server 2008 x86.
Same here. Two of the VMs the curser is a dot (Server 08 and Server 03) and one is an hourglass (WinXP).
I've reinstall the integration components and rebooted, makes no difference?- I uninstalled the "Microsoft Virtual Machine Bus Input Device Miniport", restarted and ... the dot was back to an arrow :-)

- Oh Kent !
Please let us know if it lasted and if you had other problem after uninstaling MVMBIDM I got the same error on one of my virtual Vista machines.
Did the same uninstall and "restart" :-( No luck.
Did a new uninstall.. but this time Shut Down on machine... StartUp :-) Arrow was back.
The W2k8 i did this on is still showing a nice arrow pointer.I see this as a workaround but someone at MS should really tell us WHY this is happening and present a working long term solution.
KONAB- Ok then i'll try it soon and let people know if it's working for me too...
THX, i've been looking for a fix since a long time. - Hi all,
try the following. In the VM go to the mouse-options, activate "mouse trace" and make the trace as short as possible.
Not nice, but it works ;-)
Gadoffe Here’s another workaround:
I'm having the same problem using Windows 2008 Server and Windows XP Pro. My workaround is to forget about connecting from Hyper-V Manager and use remote desktop instead. I have been working like this for two days now and so far remote desktop doesn't have this problem.
