Installing KVM for CloudPlatform

If you want to use the Linux Kernel Virtual Machine (KVM) hypervisor to run guest virtual machines, install KVM on the host(s) in your cloud. The material in this section doesn't duplicate KVM installation documentation. It provides the CloudPlatform-specific steps that are needed to prepare a KVM host to work with CloudPlatform.

9.1. System Requirements for KVM Hypervisor Hosts

9.1.1. Supported Operating Systems for KVM Hosts

KVM is included with a variety of Linux-based operating systems. The OS supported for use with CloudPlatform can be downloaded from the following website and installed by following the Installation Guide provided with the operating system.

RHEL 6.2 or 6.3: https://access.redhat.com/downloads

It is highly recommended that you purchase a RHEL support license. Citrix support can not be responsible for helping fix issues with the underlying OS.

Warning

Within a cluster, all KVM hosts must be running the same operating system.

9.1.2. System Requirements for KVM Hosts

Must be certified as compatible with the selected operating system. See the RHEL Hardware Compatibility Guide at https://hardware.redhat.com/.

Must support HVM (Intel-VT or AMD-V enabled)

All hosts within a cluster must be homogenous. The CPUs must be of the same type, count, and feature flags.

Within a single cluster, the hosts must be of the same kernel version. For example, if one host is RHEL6.2 64-bit, they must all be RHEL6.2 64-bit..

64-bit x86 CPU (more cores results in better performance)

4 GB of memory

36 GB of local disk

At least 1 NIC

Statically allocated IP address

When you deploy CloudPlatform, the hypervisor host must not have any VMs already running.

Be sure all the hotfixes provided by the hypervisor vendor are applied. Track the release of hypervisor patches through your hypervisor vendor’s support channel, and apply patches as soon as possible after they are released. CloudPlatform will not track or notify you of required hypervisor

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.
