There are two file systems involved, guest and host. What are their file systems? I know one of them is Btrfs but I can't tell if they're both Btrfs. There is a regression somewhere, I don't know where yet, when libvirt cache=none or cache=directsync, and the disk image (qcow2 in my case) is on Btrfs. The guest file system doesn't matter, it'll eventually spew some corruption related errors. 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 majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
