Mouse position causes performance problem with VMWare
Last modified: 2008-01-15 22:40:17 EST
Description of problem:
VMWare (Workstation) includes guest tools to help detect the mouse position and
determine whether the guest or host should have input.
This works extremely well in Kernel 184.108.40.206-76.fc7PAE but is completely
hopeless in Kernel 220.127.116.11-10.fc7PAE.
In the former, the mouse transitions easily and quickly with no pauses.
In the latter, there is a large multi-second pause in switching.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install VMWare Workstation.
2. Install Windows XP guest and VMWare tools in the guest. Ensure Edit |
Preferences | Input is set to grab and release input on mouse entering/leaving
3. Boot 18.104.22.168-10.fc7PAE (or probably just 22.214.171.124-10.fc7).
4. Boot 126.96.36.199-76.fc7 and you'll see near perfect behaviour.
Large pauses on moving mouse in and out of window.
Instant transition of input.
Even clicking inside or outside the guest takes a long time to recognize the
You really need to report this to vmware and see if there is an update available.
Will do. However, the fact that different kernels produce different results
suggests that they may have been a non-documented behaviour introduced.
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.
As this appears to be an issue with an unsupported application (and has had no
further update in a couple of months) I am closing as NOTABUG - indicating that
we do not believe this to be an issue with the Fedora kernel. Please do not
hesitate to re-open should you feel this to be incorrect and we will attempt to
investigate it further. Thank you for taking the time to file the original report.
