Thats all correct. >> and after that the kernel seems to hang. Qemu is emulating a piix3 >> device, and using the piix driver. This is on a pretty old kvm (version >> 28) because newer ones don't even compile. kvm-28 is ancient and there have been IDE emulation fixes since. I am not aware of issues building KVM either.

Agreed, this is very likely to be a QEMU issue (that may have already been fixed).
