The fact that most people have not noticed until now (I suppose you may have seen sporadic failures, but not taken them too seriously, like me) further shows that this truncation is actually not really done concurrently, but that the VM is still starting up by this point and has not yet opened the image. Remedy this by waiting for the monitor shell to appear before the qemu-img invocation so we know the VM is up.

This means that any attempt to write the 'file' child will end with EBADFD as the original fd was already closed. Moving bitmap reopening to the new callback which is called after permission modifications are commited fixes this as the file descriptor will be replaced with the correct one.

In the rbd cli tool documentation, the new image-spec and snap-spec are : - [pool-name/[namespace-name/]]image-name - [pool-name/[namespace-name/]]image-name@snap-name When using an non namespace's enabled qemu, it complains about not finding the image called namespace-name/image-name, thus we only need to parse the image once again to find if there is a '/' in its name, and if there is, use what is before it as the name of the namespace to later pass it to rados_ioctx_set_namespace. rados_ioctx_set_namespace if called with en empty string or a null pointer as the namespace parameters pretty much does nothing, as it then defaults to the default namespace. The namespace is extracted inside qemu_rbd_parse_filename, stored in the qdict, and used in qemu_rbd_connect to make it work with both qemu-img, and qemu itself.
