[one-users] Slow VM Deployment to VMware

[Tino Vazquez]

Hi Markus,

This may be due to the configuration NFS client of the VMware hosts
not being tuned. This article [1] may help with this issue.

Also, could it be that the VMware VM Images are bigger than the KVM
ones? What sizes are we talking about?

I also would like to point out that, to achieve the best performance
(transfer-wise) for VMware based infrastructure, we recommend the use
of VMFS partitions managed by the OpenNebula VMFS drivers [2].

Best regards,

-Tino
