Hi Michael,
I am curious, the XP numbers you are referring to, are they against the
same version of KVM/QEMU or is it something you saw in the past? It
would be interesting to track down whether this idle time consumption is
only with win7 or if it happens with all versions of windows, as opposed
to being a general problem in current KVM/QEMU.
Cheers,
Jes
