Comment 1 Luiz Capitulino 2009-05-20 22:21:28 UTC
Glauber, this is already fixed upstream (Avi's qemu-kvm.git tree) it's commit ea053add700d8abe203cd79a9ffb082aee4eabc0 .

I will attach the patch here (so that you can apply in the package, in case you won't rebase soon).

Comment 2 Luiz Capitulino 2009-05-20 22:22:21 UTC

Comment 3 Mark McLoughlin 2009-05-21 18:59:11 UTC
Glauber proposed this for the stable branch:

  http://marc.info/?l=qemu-devel&m=124286670230504

We'll pull the patch into an update soon

Comment 4 Mark McLoughlin 2009-06-03 15:06:47 UTC
I'm pushing a qemu-0.10.5-2.fc11 update to updates-testing with this fix.
