Compiling kvm Under Ubuntu Edgy i386

kvm is QEMU with support for the VT Vanderpool or Virtualization Technology. This means you can now run QEMU on CPUs that have the VT instructions and you get a super quick emulated environment. Yay!

Previously to get spritely performance out of QEMU you needed the closed-source KQEMU kernel module. Now you don't. This interests me because I use QEMU quite heavily with my little screencasting project with Ubuntu-UK. Having a totally Free (GPL) and easy to use method for running virtual machines is essential. Of course there's Xen but kvm is a great drop-in solution with very little requirements on the host, no replacement kernels for example.

Here's what I did on a core 2 duo CPU machine - this is on an utterly clean 32-bit Ubuntu Edgy system - I know it's clean, I installed it last night. This assumes that you have a stock Ubuntu kernel, and not one that you have either compiled yourself or in any way patched.
