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.
The first two patches update the xml schemas and conf to add a Ceph
secret type and to specify authentication information along with the rbd
disk.
The next two patches make some libvirt changes. We pass virConnectPtr
down into the Domain{Attach,Detach} methods (needed to access secrets
while building the qemu command), and add a helper that will escape
arbitrary characters.
The final patch replaces the current RBD qemu code and uses the new conf
info to do authentication properly. (We still need to make a change
there to avoid having the authentication key show up on qemu command
line; I'll clean that up shortly.)
Comments on this approach?
Thanks!

Subject: [PATCH 0/5] Improve Ceph Qemu+RBD support
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!
