Anyway, this is a change which I've just independently discovered is broken and I'm investigating: commit a8a1f236a2964506a22d1779648d8e1c8668cb1a Author: David Scott <dave.scott@xxxxxxxxxxxxx> Date: Tue Apr 23 10:59:26 2013 +0100 libxl: Only call stat() when adding a disk if we expect a device to exist. We consider calling stat() a helpful error check in the following circumstances only: 1. the disk backend type must be PHYsical 2. the disk backend domain must be the same as the running libxl code (ie LIBXL_TOOLSTACK_DOMID) 3. there must not be a hotplug script because this would imply that the device won't be created until after the hotplug script has run. With this fix, it is possible to use qemu's built-in block drivers such as ceph/rbd, with a xl config disk spec like this: disk=[ 'backendtype=qdisk,format=raw,vdev=hda,access=rw,target=rbd:rbd/ubun
