hi,all
i now look at qemu 2.0, i do not find rbd-api related to clone.
if qemu support this function? and from which version?

thanks.
Qemu doesn't handle that level of abstraction. The closest approximation
you could probably come up with is qemu-img's backing file support for
qcow2 images.
You should stick to using the rbd tool to create clones of rbd devices.
Alternatively, use a higher level tool (like openstack, etc)
could you tell me why 'Qemu doesn't handle that level of abstraction'?
i know qcow2 well, you can tell me the comparation。
thanks

Qemu would have to have a lot of extra code (that already exists elsewhere)
to support taking snapshots/clones/etc
