Javier has already very eloquently described the meaning of the message you're 
seeing.

I'll just note that if you need full virtualisation (for instance to run 
Windows) you could try one of the solutions he suggested (qemu/kqemu, VPC,
VMWare) and note that there is also Parallels and VirtualBox.

qemu / kqemu and VirtualBox are Open Source, Free software.  The others are 
commercial.

I've been rather impressed with VirtualBox on my pre-HVM machine recently.

I'll also note that Xen/HVM, VirtualBox and kvm all use code from the qemu 
project, so in some sense it's one of the "parents" of Open Source 
virtualisation.

Xen only supports a relatively low performance 2D graphics interface for 
guests.  There is a Free OpenGL virtualisation solution called VMGL by H.  
Andrés Lagar-Cavilla (http://www.cs.toronto.edu/~andreslc/xen-gl/) although I 
don't know if that's in continuing development.  It can run some full 
featured GL apps, as you can see from the screenshots.  I don't know if it 
would support Compiz, though.

It won't work with Windows guests, so its applications to gaming are somewhat 
limited by that.

3D virtualisation is hard.  VMGL was one approach to it, Jacob Gorm Hansen did 
some work on it too.  I know other people who have been looking into 3D 
virtualisation under Xen but I can't guarantee what they'll produce or when 
they'll produce it.

There are also people working on 3D virtualisation for other virtual machine 
programs, both Open Source and proprietary.  I think we'll see more solutions 
popping up in the future.

It would be nice but there are no concrete plans for if / when Xen will have 
full 3D support for domUs.

Cheers,
