This reverts commit 035db37394ad11a39d47f8bd2b6a8a2734283cbf
Even though we only allow using RBD with raw volumes,
removing the options and the default format causes our
parser not to fill out the volume format and the backend code
rejects creating a non-raw volume.
Re-introduce the volume options to fix volume creation while
erroring out on requests to use non-raw formats.

When we allow multiple instances of the driver for the same user

however source dir paths were left unsanitized.
A netfs pool with:

</source>

virStorageBackendFileSystemIsMounted, because it shows up in the

The current qemu driver code for changing bandwidth on a NIC first asks
the network driver if the change is supported, then changes the
bandwidth on the VIF, and then tells the network driver to update the
bandwidth on the bridge.
This is potentially racing if a parallel API call causes the network
driver to allocate bandwidth on the bridge between the check and the
update phases.
Change the code to just try to apply the network bridge update
immediately and rollback at the end if something failed.

The domain conf actual network def stores a <class id='3'/> element
separately from the <bandwidth>. The class ID should really just be
an attribute on the <bandwidth> element. We can't change existing
XML, and this isn't visible to users since it is internal XML only.
When we expose the new network port XML to users though, we should
get the design right.
