With the patches I've posted to the list libvirt should be mostly
prepared to use -blockdev instead of -drive to specify disk images.
There's one gothcha though. Internal snapshots don't work due to qemu
considering every monitor-owned node for snapshot as well. With blockdev
everything became monitor-owned including the 'file' nodes which are
definitely not snapshottable. Even when qemu fixes that bug I don't
think it will be introspectable.
Our options are either to wait for the qemu fix and then try to detect
it somehow, perhaps as a version check (yuck), or go ahead and inform
users to upgrade to a newer qemu afterwards.
Any other ideas or suggestions?

New subject: [libvirt] [RFC PATCH 1/2] qemu: caps: Add capability for dynamic 'auto-read-only' support for files
Initial implementation of 'auto-read-only' didn't reopen the backing
files when needed. For '-blockdev' to work we need to be able to tel
qemu to open a file read-only and change it during blockjobs as we label
backing chains with a sVirt label which does not allow writing. The
dynamic auto-read-only supports this as it reopens files when writing
is demanded.
Add a capability to detect that the posix file based backends support
the dynamic part.

But the constant has the words in a random order.
Would QEMU_CAPS_BLOCKDEV_DYNAMIC_AUTO_READONLY be enough?
It's internal so we can rename it later if needed.
Also, the capability rewrapping script should be capable of handling
two-line comments. (Three lines would require changing it)

New subject: [libvirt] [RFC PATCH 2/2] qemu: enable blockdev support
We require that 'auto-read-only' is dynamic for posix-file backeds this
prevents problems with libvirt's usage of sVirt where we don't grant
qemu permissions to write backing chain until it's needed.
