Convert qemu emulation to KVM

Hi,

I have a strange problem, while creating Virtual machine By mistake I’ve selected qemu as the emulation type. Now I want to change it to KVM.
I cannot re-install the image since I’ve done lots of configuration inside the VM.
My environment is:
Base - Ubuntu 9.04 x86_64
Processor: Intel
Virtualization tools: virt-manager, qemu
Virtual Machine OS: Ubuntu 9.04 64 bit.

Need help asap.

Regards
Srikanth
