The Atom core (cpu name n270 in QEMU speak) supports MOVBE. This is
needed when booting 3.8 and later linux kernels built with the MATOM
target because we require MOVBE in order to boot properly now.

Right, I don't know what v1.4 is
It's the QEMU release that we're about to make in a week. :-)

Personally I wouldn't mind declaring n270 as a non-migratable CPU
model. But libvirt supports n270, so it

It wouldn't be a bug fix without extracting the patch out of
my x86-next tree that actually implements movbe.
This is problematic since the n270 qemu model won't boot a real kernel compiled
for that box.

If you don't have the implementation of MOVBE working (and included on
TCG_EXT_FEATURES), neither your patch or +movbe can help you.
Yes, running -cpu n270,+movbe with Richard's patchset merged works.
Thanks.
