btw, it changes the behavior for "-cpu base" with accelerator.
I think it should be OK considering "-cpu base" seems only for
experiment case.
Yeah, I wonder if it should even be user creatable.
Per commit 5adbed3088d ("i386: Define static "base" CPU model"):
Despite having no CPUID data set at all, "-cpu base" is even a
functional CPU:
* It can boot a Slackware Linux 1.01 image with a Linux 0.99.12
kernel[1].
* It is even possible to boot[2] a modern Fedora x86_64 guest by
manually enabling the following CPU features:
-cpu base,+lm,+msr,+pae,+fpu,+cx8,+cmov,+sse,+sse2,+fxsr
Anyhow I don't mind if it becomes hidden.
