You don't.
(K)Qemu is the fastest (raw cpu) of them all but not for graphical stuff (It does have an OpenGL patch/option though). As far as I know, it doesn't
"emulate" high end cards...
Qemu (and kqemu/kvm) is not a good option if you're looking for graphical performance. (This could change though, KVM is getting better with every release).

Thats what I thought but I am always willing to learn something new.
About the speed thing:
Dunno - last time I tried kqemu it was kind of sluggish for compiling.
It's hard to say because reliable benchmarks of VM's are hard to find.I read that Vmware even expicitly prohibits publishing benchmarks in their license.

Did you try it with a headless VM ?
I use it like that with RDP to avoid the sluggish graphics emulation.
I find the speed difference very noticeable compared to VMWare.
Virtual Box isn't bad for this either (but more aimed for desktop systems).
Never used qemu headless - wouldn't make a difference either because I normally don't run a GUI in VM's.
Virtualbox (usuaslly run the headless either) was faster at the time which didn't make much sense since it shares a lot of code with qemu.

Well, I must admit that I don't know Virtualbox that good.
We mostly use Xen (RHEL, IBM), but that only makes sense for networking (xen beats everything here).
We do have a number of servers (mostly running drupal) using kvm and I'm really happy with those. Qemu's best thing is its raw cpu performance (IMHO, still the most important part).
If you do servers you might be interested in disk I/O which doesn't seem too great on any VM.
desides running any benchmark on VM's is funny business from my experience.
I am wondering where M$ is going with their next VM - either they go halfbaked as usual or if they really want to get all the way they'll have to include 3d for vista.
Never heard about anybody doing this - I know there is some prealpha software to get some 3d going but attaching a video card directly to the VM is news to me.
