Yes, actually without the drivers you won't get any better performance
at all.

You can look at /var/log/Xorg.0.log (assuming X is running on :0) and
see which driver it says you are using. Look for lines saying something like
Loading .._drv.so
containing qxl (I haven't used the X driver myself, I'm using windows guests).

> Do I need to install qxl drivers on the host also?
No, the host X has nothing to do with it. Actually the host doesn't have to run X
at all (unless you are also running the client on it).
