Boot all yes config kernel with QEMU

Hi, I'd like to build and boot an allyesconfig kernel with QEMU. Building is no problem but when I try to boot it I get problems because the host system does not support features requested by the VM. How does one go about testing an allyesconfig kernel? Back story: I'm trying to set up some CI infrastructure to run scripts/leaking_addresses.pl against the various stable kernels. thanks, Tobin.
