As per first post, kvm worked for me on Ubuntu 12.04 32 bit with whatever 3.* kernel that was. I have upgraded to a new box with newly installed Ubuntu 12.10 64 bit and now kvm does not work. Same qemu image. I suspect the architecture change from 32 to 64 bit is the issue here but I guess you are suggesting it may be related to the kernel upgrade?
