i didn't try KVM - i did try XEN - and it, too, works in a similar 
)Crappy) manner. i didn't compare it "head to head" with vmplayer on the 
same machine - but it is quite very slagish.

with xen, i did manage to find some... driver(?) that made the mouse 
pointer work much better then without it - did you look for something 
similar for KVM?

i think that the main issue, is that vmplayer is a down-sized version of 
a commercial GUI program (vmware workstation) - and these programs tend 
to be far more polished then "technology-oriented" programs, such as 
qemu. it could be that since KVM is "commercial" meant mostly for 
desktops - they'll have better support in the future - assuming there is 
no collision between the commercialization-efforts of nucleolus/redhat 
and the free-software-ness of the KVM kernel part.
