Setting to POST since there's a patch available, I pull it into the next build

Thanks, taking out of POST. If another fix goes in after 2.1, please comment here so I don't miss it (I'll keep my eyes open too)
Just for info. The resent patches are available. See another thread of me BZ1165336 that is about the same topic. The fix has been sent to the official stable qemu mailing list: http://lists.nongnu.org/archive/html/qemu-stable/2014-09/msg00276.html http://lists.nongnu.org/archive/html/qemu-stable/2014-09/msg00275.html We can wait for feedback in BZ1165336 and you could add the patches to 1.6.2 in FC20 Thanks in advance.
Hi Cole, as explained in BZ1165336 these are the required patches: http://git.qemu.org/?p=qemu.git;a=commit;h=9a48bcd1b82494671c111109b0eefdb882581499 http://git.qemu.org/?p=qemu.git;a=commit;h=317b0a6d8ba44e9bf8f9c3dbd776c4536843d82c Can you cherry pick them for qemu 1.6.2 (FC20) and 2.1.2 (FC21)?
