On my F12 laptop I experience the following issue:
If my cursor is in a KVM instance (RHEL 5) and I leave the machine for a while the Fedora screen saver with lock does not kick in. That is until I press CTRL-ALT to take focus from the RHEL instance back to my Fedora 12. Then the screen saver kicks in.
Apart form being a little annoying it is also probably a security issue. If I want the screen saver to kick-in after 5 or 10 min of idle time and require a password it is probably NOT a good idea for the KVM focus to somehow override this setting.
Regards, William

Agreed.
Could you please open a bug against Fedora 12 at bugzilla.redhat.com? The most likely component is virt-manager judging from your description.

To be honest, I don't see a disconnect on that. If the cursor's in a KVM window, I'd expect the main screen to remain active as it's being used to display the KVM window. I'd think it'd rather annoying to have the main screen (and consequently the KVM window) go into screen saver mode while I was working on the VM.
I don't know that the host would (or could) know when the VM goes into screen saver or if it'd be a "good thing" to have that propagate to the host. I don't use KVM or Xen for GUI-based systems generally (unless I'm forced to fire up Winblow$ in a VM). Most of my virtualizations are for Linux-based servers which I run in non-GUI mode.
I can say that I've run into a similar thing using Synergy. I have the Synergy server (the thing that owns the keyboard and mouse) on an F11 machine, with two F12 machines as Synergy clients. If I have the mouse on one of the clients, the server's screen saver does kick in (in Synergy the keyboard and mouse are shared but the display is not-- unlike KVM) so this is expected.
However, the energy saver (screen blanking) on the server doesn't occur until I move the mouse back to the server's screen and hit a key. I suspect this is just the way Synergy works, rather than a bug in an underlying library. It's not that annoying. I expect it. It's just kinda odd.

Are you by any strange chance saying KVM as in switch, rather than as in virtualization??

If you read his initial post, he says "if my cursor is in a KVM instance". My reading is that's KVM virtualization, not a keyboard- video-mouse switch.

I'd think it'd rather annoying to have the main screen (and consequently the KVM window) go into screen saver mode while I was working on the VM.
Except that if the host's Xorg is used to display an application like OpenOffice.org or Firerox, I would still expect it to lock the screen if there is not keyboard activity. The key is not the displaying of anything but the inputdev activity.
Likewise, if I am working on the VM through the host, the host will see keyboard or mouse events and should not enable its screensaver.
I still feel it is a bug :)

+1.
Let me be clear. This is after there has been no activity (keyboard or mouse) for either the host or the guest. (I'll use the host guest terminology)
So e.g. I've been working in a guest and the focus is there. I leave my machine and go make a cup of tea and then get interrupted with a phone call. I return to my machine and the screen saver with lock has not kicked in (if I had it enabled in the guest then the guest would have that but I'm not worried about that.) I decide to check email on my host and I CTRL-ALT out to the host. Then the screen saver and lock kicks in. So as long as someone didn't ctrl-alt out they could see what's running on my desktop. (And it is also annoying to have the unexpected behavior of the screen saver kicking in at this time versus when I return from wherever.)
I think what should happen is that the host also recognizes the lack of activity and turns on the screen saver. Can it do that?

Interaction between screen saver isn't new, I have it off in the host under most of my systems, and use SS in the VM. I'm running KVM, not libvirt stuff.
