Those commits are already included into 2.1.0 release tag. I tested
almost any commit refs from tag v2.1.0-rc3 to v2.1.0. Things get broken
with the commits above with or without following commits.

I'll wait for the next 2.1.x release on git.qemu.org to test again. I
actually prefer not to use master to build packages for my bleeding-edge
Ubuntu-based distro.

Thanks!
