[one-users] Slow VM Deployment to VMware

[Markus]

Hello,
I'm working with a small OpenNebula infrastructure with 2 KVM and 1 VMWare host. All datastores are realized as a NFS share, located on the frontend machine.

When creating a new virtual machine, I experience the following behavior:
The copy and deployment process of a VM to an KVM node lasts only about 2 minutes, but a deployment to the VMware node lasts up to 6 minutes. Is there an explanation for this big difference?
All resources are working in the same local network. The datastore for KVM images uses standard filessystem as datastore manager and the one for VMware uses VMware datastore manager.

Looking forward to some explanations.

Thanks,
Markus
