The current refresh rate QEMU uses is quite low and the mouse interactivity is poor in comparison with vmware + vmware tools. I am currently using the attached patch to improve the mouse interactivity - it shortens the screen refresh interval to 10 ms when the mouse or keyboard is active, and returns to 30 ms after a 100 ms inactivity period. Hi Jindrich, Thanks for posting this. Is there a particular guest that you find best demonstrates this? IMO any guest that uses the mouse. I use KVM to run WindowsXP, where the effect is clearly visible, but it will be the same in XWindow. Hi Jindrich, Sorry for the delay in getting on this. I notice your patch stalls the system when -vnc is used. Do you have any idea why? I'll look into it, but I thought I should check with you first.

KVM will inherit it from qemu. Is there a way to test with QEMU that is not painfully slow? Cam - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems?

My preference is allowing CPU features to be passed to the guest. So I two things: I want to check if anyone is working on these already and if not can someone please expand a little on what is wanted? Any feedback or pointers on what features would be most useful is also welcome.
