tries to search for an i386 kernel to install 64bit system

Version: 0.600.0-1ubuntu1

Having imported and tried to use koan to install a 64-bit VM (as per
https://help.ubuntu.com/community/Cobbler/Deployment) virtinst seems to want to use i386 kernels. I've attached a patch which fixes it for me - I'm assuming arch is the architecture due to be installed :-)
