[libvirt] [PATCH 0/5] Improve Ceph Qemu+RBD support

[Sage Weil]

The current support for qemu and Ceph RBD (rados block device) has two 
main deficiencies: authentication doesn't work, and it relies on 
environment variables (which don't work with latest upstream).

This patch set addresses both those problems, while trying to integrate as
cleanly as possible with the rest of libvirt.

The first few patches make some changes to libvirt itself: adding a CEPH 
secret type (for Ceph/RBD authentication), adding authentication fields 
to the XML schema, passing the virConnectPtr into the 
Domain{Attach,Detach} methods (needed to access secrets while building 
the qemu command), a helper that will escape arbitrary characters, and 
finally a patch that replaces the current RBD qemu code.

Comments on this approach?

Thanks!
