Couldn't reproduce this in a quick test with a random guest I had available. What is your complete qemu command line? Is the problem new with the 3.0 RCs or does it also happen with kernels that my existing guests are likely to have in use - say, the F15 kernel? I guess with virtio-blk you don't see the problems?
