That would be great of course! We would use the feature mainly to
simulate NMI/MCE handling as these are harder to test with real hardware.

QEMU has:

nmi cpu
mce cpu bank status mcgstatus addr misc

But maybe it would be better to allow:

inject cpu vector[0..255]

and treat only mce separately.

We currently use model=corei7_ivy_bridge_3770k
