Chapter 9. Installing KVM for CloudPlatform

• private.network.device

These should be set to the name of the bridge that the user created for the respective traffic type. For example:

• public.network.device=publicbondbr0

9.5. Time Synchronization for KVM Hosts

The host must be set to use NTP. All hosts in a pod must have the same time.

1.Log in to the KVM host as root.

2.Install NTP.

#yum install ntp

3.Edit the NTP configuration file to point to your NTP server.

#vi /etc/ntp.conf

Add one or more server lines in this file with the names of the NTP servers you want to use. For example:

server 0.xenserver.pool.ntp.org

server 1.xenserver.pool.ntp.org

server 2.xenserver.pool.ntp.org

server 3.xenserver.pool.ntp.org

4.Restart the NTP client.

#service ntpd restart

5.Make sure NTP will start again upon reboot.

#chkconfig ntpd on

9.6. Primary Storage Setup for KVM (Optional)

CloudPlatform allows administrators to set up shared Primary Storage that uses iSCSI or fiber channel. With KVM, the storage is mounted on each host. This is called "SharedMountPoint" storage and is an alternative to NFS. The storage is based on some clustered file system technology, such as OCFS2.

Note

The use of the Cluster Logical Volume Manager (CLVM) is not officially supported with CloudPlatform.

With SharedMountPoint storage:

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.
