Description Peter Krempa 2017-11-15 15:27:11 UTC
Description of problem:
To allow using blockdev-add for external snapshots (blockdev-snapshot) or blockdev mirror it's necessary to create qcow2 or other formats. Currently it would require a call to qemu-img which is not really a good idea for libvirt since it's hard to manage qemu-img or figure out whether it supports a given format (due to lacking introspection).

The formatting should be an asynchronous block job since it may take a long time if storage is blocked.
