It seems like it may not be a kernel bug. I've been able to reproduce, and not reproduce it, with kernel 3.18.9, varying in some other factor (Fedora 21, vs Fedora 20 live installs).
The short version, With these, the problem does not reproduce: libvirt-* 1.1.3.9 qemu-* 1.6.1 With these, the problem does reproduce: libvirt-* 1.2.9.1 qemu-* 2.1.2 I've updated the bug with the details of versions and the exact qemu command for the reproducing and non-reproducing cases. https://bugzilla.redhat.com/show_bug.cgi?id=1204569 Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
