oh no, we don't add capabilities in the middle - only at the end.
and I think we should name them "drive.l2-cache-size" and
"drive.refount-cache-size" since they're "-drive" attributes.
You could even be more specific "drive.qcow2.l2-cache-size"

this would technically I believe be something along the lines of :
-drive file=$path,format=qcow2,refcount-cache-size=$size

This is not the preferred mechanism to do this. Is there no other way to
determine that those attributes exist?
It seems its not easy since the parameter is then based off of
format=qcow2 and further validation using virQEMUCapsCommandLineProps
virQEMUCapsCommandLine[] is not possible. Maybe someone else has a
bright idea.
The name should incorporate DRIVE, e.g. QEMU_CAPS_DRIVE_L2_CACHE_SIZE
(likewise for others since they're a -drive properties, kinda). Maybe
even use "QCOW2" instead of "DRIVE"

With QEMU 2.8 we could determine this via query-qmp-schema, but you seem
to want 2.2 and beyond...
I almost think we should only do this via the introspection via adding
to the virQEMUCapsStringFlags virQEMUCapsQMPSchemaQueries[] entries:
{ "blockdev-add/arg-type/+qcow2/l2-cache-size",
QEMU_CAPS_DRIVE_L2_CACHE_SIZE },
{ "blockdev-add/arg-type/+qcow2/refcount-cache-size",
QEMU_CAPS_DRIVE_REFCOUNT_CACHE_SIZE },
{ "blockdev-add/arg-type/+qcow2/cache-clean-interval",
QEMU_CAPS_DRIVE_CACHE_CLEAN_INTERVAL },
Perhaps others would have comment here too...

Likewise... but 2.5 and beyond.

Rather than checking format here, this should be done somewhere in the
XML validation to ensure that these parameters aren't added to a disk
with driver unless qcow2 format is being used.
Thus not needing the errors below... More recent push is to not format
or validation error checking once the command line is being built as
this should already have been done.
That way all that is added is what you have in patch1...
