[Qemu-devel] "console: Properly switch consoles for screen dumps" breaks qxl screen dump

[Alon Levy <alevy@redhat.com>]

Hi Jan,

 I've recently found the $SUBJECT, it's commit
  f81bdefb63243e82d16ce49332f7cf74d10b8f27.

 I'd like to fix it without breaking anything, can you provide me with
 the test that your original patch fixed?

p.s. for a simple command line with a single console (not even sure how
to get multiple) the following fixes my problem, I expect it doesn't
introduce any problems?
