Re: [Qemu-devel] from which version qemu support clone on rbd

[Brian Jackson]

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) that 
supports this.
