Hi,

I do not remember exacly, but you might check the source code of
hosted engine's VdsmBackend where we do that too.

https://gerrit.ovirt.org/gitweb?p=ovirt-hosted-engine-ha.git;a=blob;f=ovirt_hosted_engine_ha/lib/storage_backends.py;h=f2fbdc43d0e4afd7539a3a1de75de0cb07bdca9d;hb=a012f184584af20d3dba8038d73b8d9b447af7b3

I think you are missing the prepareImage call.

Regards
