Thanks Wolfgang.

I had already prepared a v10 with the cleanup ;)

I'm currently on holiday, so don't have too much time this week.


yes, for nbd tls, this need qemu 2.8 + blockdev-add / blockdev-mirror.
Too much change for now. (and blockdev is still experimental and not completed)

Objet: applied: live storage migration v9

Applied the series with some followup patches: 
* Added patches for the timeout and POSIX::_exit() changes I mentioned. 
* Also added some whitespace & style cleanup patches. 

Now we need to figure out whether to first add the ssh-tunnel based 
ecnryption or go with qemu's tls. Saw the thread on qemu-devel about 
nbd&tls and blockdev-add - sounds inconvenient until we're >= 2.8. 
(There's also one about the nbd handshake being able to block qemu's 
main thread... should be hard to trigger, plus the socat timeout should 
catch this as well AFAIK.) 

Sending the followup patches to the list now.
