NIC Bonding for XenServer (Optional)

1. Find the physical NICs that you want to bond together.

#xe pif-list host-name-label='hostname' device=eth2

# xe pif-list host-name-label='hostname' device=eth3

These command shows the eth2 and eth3 NICs and their UUIDs. Substitute the ethX devices of your choice. Call the UUID's returned by the above command slave1-UUID and slave2-UUID.

2.Create a new network for the bond. For example, a new network with name "cloud-public".

This label is important. CloudPlatform looks for a network by a name you configure. You must use the same name-label for all hosts in the cloud for the public network.

#xe network-create name-label=cloud-public

#xe bond-create network-uuid=[uuid of cloud-public created above]

pif-uuids=[slave1-uuid],[slave2-uuid]

Now you have a bonded pair that can be recognized by CloudPlatform as the public network.

8.10.4.5. Adding More Hosts to the Cluster

With the bonds (if any) established on the master, you should add additional, slave hosts. Run the following command for all additional hosts to be added to the cluster. This will cause the host to join the master in a single XenServer pool.

#xe pool-join master-address=[master IP] master-username=root master-password=[your password]

8.10.4.6. Complete the Bonding Setup Across the Cluster

With all hosts added to the pool, run the cloudstack-setup-bonding script. This script will complete the configuration and set up of the bonds across all hosts in the cluster.

1.Copy the script from the Management Server in /usr/share/cloudstack-common/scripts/ vm/hypervisor/xenserver/ to the master host and ensure it is executable.

2.Run the script:

#./cloudstack-setup-bonding.sh

Now the bonds are set up and configured properly across the cluster.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
