1. For the current version we provide the XCP format virtual machine images Domain U The Xen Cloud Platform or XCP is a turnkey open source virtualization solution that provides out of the box virtualization and cloud computing XCP includes the Xen Hypervisor the enterprise ready Xen API toolstack and integrations for cloud storage and networking solutions For more information about XCP users can find from here 2 1 VM image We provide three VM images for the user to download and import to their own virtual environments The Table 1 lists the VM image name and corresponding services it provide Table 1 VM image information VM image name Description SearchFront xva Search benchmark front end service SearchBack xva Search benchmark back end service MediaStreaming xva Media Streaming service 2 2 Import the VM The users need to import the VM images to their own XCP environments by using the 1 XCP main page http www xen org products cloudxen html following command xe vm import filename path to your image 2 3 Prerequisites After importing the VM images After importing the images there are some configuration files user needed to modify Users should pay attention that the images we provided are only the services Users should deploy the corresponding workload generator to drive the services How to deploy the workload generator will not be discussed in this guide for we have detailed them in the other two u2.
