No, it's not in 3.4.1, and it won't be in any later 3.4.x. qemu upstream have been racing ahead and playing catchup didn't seem to be working well so I'm hoping that the qemu will fork a stable branch in time to update to it for Xen 3.5, in which case this problem will be fixed then. > If that's not in, is there any plan how to deal with scenarios like > mine?

I haven't analysed this use case in detail and it would depend on the exact structure of your storage. Alternatively a workaround for you might be to force it always to assume qcow2 for files rather than raw, if you don't have any raw disk files.
