Hi Alex, thanks for this and we'll hear in a few :-)

In general the way I see this is that we should start upstreaming one small thing at a time, rather than wait for a perfect solution which starts to include more and more patches and diverge more and more from upstream qemu.
I don't think we want to maintain a separate "MT" branch right?
