I don't see that there's anything we can do in virt-manager. We have no choice but to grab the keyboard & mouse when using guest VNC consoles without a USB Tablet / other absolute mouse pointer. I'd expect the screensaver/screenlock to be able to override any other application's active mouse / keyboard grabs when it tries to activate. Re-assigning to g-s-s Daniel,
Thanks for fast response!

Could you explain how this can be done? Assume app#1 already uses
XGrabKeyboard for a grab; now app#2 tries to steal the grab by
XGrabKeyboard? But man page of XGrabKeyboard says
If the keyboard is actively grabbed by some other client,
XGrabKeyboard fails and returns AlreadyGrabbed.
So how will app#2 steals the grab?
I'm still not convinced the screensaver should be dependent upon XGrabKeyboard if it is used as a "security measure".
It really means ANY application can grab the keyboard and prevent the screensaver from loading or it loads its own "fake" screensaver to steal your password.
Should this really be dependent on the application writers in this case libvirt to "do the right thing"? It seems like it should be handled at a lower level to prevent mis-use.
I have the same expectations as daniel:

I don't know how gnome-screensaver can implement what it needs, but I am sure that other applications like virt-manager should not need to be modified to take account/be aware of g-ss's needs. *** Bug 573045 has been marked as a duplicate of this bug. *** This message is a reminder that Fedora 12 is nearing its end of life.

Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. This bug should be reopened and renamed; it also affects Fedora 13 and is more general than just with VMs. It also occurs using synergy for input device sharing, or according to some Ubuntu bug reports when certain menus are left open. It is a security issue, and WONTFIX is correct for virt-manager but almost certainly not for gnome-screensaver. This message is a reminder that Fedora 13 is nearing its end of life.
