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.

As Alice once said, "Curiouser and curiouser!"
