Yes, this is fantastic! Thank you for tracking down the regression and drafting
a patch. CPU consistency between host and VM, and correct identification, are
likely to become increasingly important as the Meltdown/Spectre fixes make
their way into the kernel. Under Linux, some of the mitigation strategies are
dependent upon correct CPU identification, and microcode patching and
capabilities flags may be passed up to the virtual guest.
