As you may have followed, I compiled my KDE in a virtual machine, described an example how it goes and even compared compile times in a mini-benchmark. I stopped using a virtual machine later because VirtualBox only gives you one virtual CPU, QEmu as well, and VMware Server only two. The good thing is I found KVM virtualization and learned how to set it up. It is a bit tedious and you will have to create a network bridge after every reboot, but the result is astonishing - I could compile Qt 4.6 in 20 minutes instead of 80.

KVM has very good performance - try virt-manager
KVM has a very good performance. I did the following benchmark with Geekbench
Tested with Ubuntu 10.04
Native: 2870
Kvm: 2560
The number is a score in Geekbench. The virtualized machine has a benchmark result of 89% of the native benchmark result.
To compare with an older benchmark I ran:
Ubuntu 9.10
native: 2350
Virtualbox: 1512
You can get around the tedious work of using KVM by using Virt-manager which is a manager for virtual machines created by Red hat. It can control both Kvm/qemu and Xen - locally or remote - however it needs libvirt installed on the remote machine. I'm using virt-manager 0.8.2 which works quite well. I've experienced that earlier releases were a bit buggy, at least under Ubuntu.
seems I found a soul-mate :)
yes, I have stopped using VirtualBox and yes, I am using virt-manager as described in one of the links above. GeekBench is something that interests me a lot, so I need to stop commenting here.
