Tested with qemu 1.6.1 (commit 62ecc3a0e3c77a4944c92a02dd7fae2ab1f2290d). Looking through old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays? I don't have the latest version yet, but I just tested it with 2.3.0 and it works. Ok, thanks for testing. So if this has been fixed in QEMU 2.3, I assume that it is still fixed, thus let's close this ticket. If you hit the problem again with the latest version of QEMU, please re-open this bug or create a new one.
