Since we allow overriding cpuid flags, why not the vendor string?
It's necessary for cpu passthrough.
But we don't allow explicit override of cpuid flags today. We support
choosing CPU models which include vendor id and cpuid flags.
I think we allow "-cpu qemu64,-nx" for example.
Introducing a host CPU model would be acceptable and would more
accurately achieve cpu passthrough.
I agree that "-cpu host[,modifiers]" is desirable. But I don't see why
we shouldn't support finegrained control.
It's probably better done through a "-cpu blah,-nx,vendorid=foobar"
rather than a separate option.
