Hi Dimitri,

Where in ceph.conf do I tell it to use qemu and librbd instead of
kernel module?

You do not need to specify that in ceph.conf.

When you run qemu then specify the disk for example like this:

  -drive format=rbd,file=rbd:/pool/imagename,if=virtio,index=0,boot=on


Small typo :) It has to be:

 -drive format=rbd,file=rbd:pool/imagename,if=virtio,index=0,boot=on

Wido

Where you replace "pool" and "imagename" with whatever you have called
them.

You can create new images with the qemu-img utility.
