Apache Cloudstack Implementation Step by step Part 2 - Hypervisor Configuration

After the OVS configuration, We have to install XenCenter and configure the XenCenter to create XenServer cluster so lets begin...

  Xencenter is available as windows installation binaries  which you can Download from here. The install process is quite strait forward so i am not including that in the post.

 once XenCenter is installed create a pool and add all the hosts to pool.

     Once all the hosts are added all the iSCSI storage to the pool by clicking on Create new SR.
     Now the infrastructure should looks like bellow screen

    Lets have a look at complex part THE NETWORK . Now that we have storage, server resources ready we have to prepare network resource for cloud
we have to create total 3 networks in xenserver pool named as Management, Guest and public. In our environment we wil configure this environment with NIC redundancy using bond configuration.
  Bond1 - Nic0 and Nic2 (management) - for Cloudstack VM and Hosts traffic (10.3.4.x/24) 
  Bond2- Nic1 and Nic3 (Public)  - for Guest inside and actual LAN traffic (10.3.5.x/24)

 Click on cluster and navigate to network tab and proceed to create new network.   

 Select Bonded network to create redundancy for management and cloud traffic.
Create bond network by selecting Nic0 and Nic2 for management traffic with active passive configuration. Create the same configuration with Nic1 and Nic3 for Public and guest traffic.

Create 3 virtual machine with CentOS base installed operating system for 2 cloudstack management servers and 1 database server. Navigate to Part 3 for Cloudstack Installation and configuration.
