Luiz,

Can you pick up to your tree?

Yes, this is queued for review for 1.7. I should start reviewing patches for 1.7 in the end of this week or in the beginning of next week.

Convert stderr messages calling error_get_pretty() to error_report().

Timestamp is prepended by -msg timstamp option with it.

Per Markus's comment below, A conversion from fprintf() to error_report() is always an improvement, regardless of error_get_pretty().

But, it is not reasonable to convert them at one time because fprintf() is used everwhere in qemu.

So, it should be done step by step with avoiding regression.

Applied to the qmp branch, thanks.
