I still lose mouse focus (partial grab failure)

I still lose mouse focus (partial grab failure)

[Bill Davidsen]

Sorry to be beating a dead horse, but I have gotten some mail from people with 
similar problems, and asking if I have a solution.

The problem is loss of mouse focus (but not keyboard) running VMs under KVM. My 
systems are all Fedora and GNOME, but range from FC6 on i6600 with KVM-45 to FC9 
and FC10 on assorted multi-core Intel and AMD 64bit CPUs, all in 32 bit mode. It 
happens with Linux, XP, and Windows7, using single or smp modes, and doing Linux 
boots with various clock sources.

After running for a time, sometimes seconds and sometimes many minutes, the 
mouse will lose focus and operate in the host space. This happens whether 
running full screen or in a window (not a VNC issue as suggested by one person). 
The keyboard remains in the VM, and when in a window the label still suggests 
Cntl-Alt to toggle grab.

Essentially identical problems have been reported in Ubuntu and SuSE on some of 
the other lists and boards I have been using. Now that I have many VMs running 
(server consolidation) this has gone from annoying to a serious time waster.

Another possibly related issue is rare keystroke issues, where a single 
keystroke will be missed or repeated. That only happens a few times a day, but 
it is common to all machines.

Suggestions, workarounds, or further confirmations welcome.
