qemu hasn't been updated for over a week. However I'm having a hard time understanding how even a change to qemu's caching would in any way affect only btrfs and nothing else. The libguestfs test suite is extremely comprehensive and tests many other filesystems, and none of them are failing. These guests are built on the fly from the latest packages in Fedora, so any other package might be the cause, but it seems like the kernel is the most likely candidate. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine. Supports Linux and Windows. http://et.redhat.com/~rjones/virt-df/ -- 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
