We present the prototype deployment of a private cloud at PIC and the tests performed in the context of providing a computing service for ATLAS. The prototype is based on the OpenNebula open source cloud computing solution. The possibility of using CernVM virtual machines as the standard for ATLAS cloud computing is evaluated by deploying a Panda pilot agent as part of the VM contextualization. Different mechanisms to do this are compared (EC2, OCCI, cvm-tools) on the basis of their suitability for implementing a VM-pilot factory service. Different possibilities to access the Tier1 Storage Service (based in dCache) from the VMs are also tested: dcap, NFS4.1, http. As a conclusion, the viability of private clouds to be considered as a candidate implementations for Tier1 computing services in the future is discussed.
