[one-users] OpenNebula 3.4 and Esxi 5.0- image cloning task throws error

[Tino Vazquez]

Thanks a lot Anil, this kind of feedback is really valuable for us.
The Shared transfer driver makes sense to be slower in 3.4, but the
front-end gains in stability and lower load, which I think is a good
trade-off. Other, more customized, deployments can be fine tuned if
you also want fast VM deployment time.

Best regards,

-Tino
