Happy New Year to all! As my first post of 2012 blog, I would like to wish everyone a very healthy year, prosperous and productive future. There are certainly some interesting technologies coming our way!
In this three-part blog series, I'll run through a XenDesktop environment setup / Basic POC at a high level with pointers on how to save time and streamline the process 'installation. First, let's take a look at the configuration of the hypervisor in this position with XenServer. Then we will examine the XenDesktop controller and install the components associated with two columns. Finally, we will conclude with the delivery of application in the last post using XenApp. So follow, post comments and share your own experiences with desktop virtualization configurations!
Why exactly am I called this series 10 Xen? Aside from the title sounds good, I hope to prove that the establishment of a basic XenDesktop environment can be accomplished in pieces that take 10 minutes or less. At Citrix, we strive to develop products that are both easy to install and configure and still provide professionals with the level of control they need to effectively integrate with their environment. It is a continuous effort to find the perfect balance with each new feature and option configuration.
So, let's begin! I will use the following hardware and software
Hardware:
HP ProLiant BL460c Server Blade
2x Dual-Core Xeon 3.33 GHz @
16GB RAM
500GB local storage
1 Gbit LAN
Software
XenServer 5.6 SP2
XenDesktop 5.5
XenApp 6.5
windows Server 08 R2 and windows 7 VM
to start, I need to install XenServer 5.6 SP2. I'm going with this version because it is the one recommended for XenDesktop 5.5 and Machine Creation Services. XenServer can essentially be installed in one of three ways: from CD / DVD media, USB flash drive, or from the network via PXE boot. I will install XenServer here from a USB flash drive of 1GB using the steps below
- Download XenServer 5.6 SP2 ISO Image
- Download and run PendriveLinux from http :. //www.pendrivelinux .com / universal-usb-installer easy-as-1-2-3 / to assist in the creation of the boot sector on the flash drive and writing the image
- Select "Try Unlisted Linux ISO (Old syslinux)" in the distribution of combo (use "Try Unlisted Linux ISO (New syslinux)" if installing XenServer 6.0)
- Browse to the image and XenServer ISO then let PendriveLinux write on the flash drive
Note: I chose to manually install from a flash drive, because it is a fast and efficient method. Installing XenServer from a CD / DVD can take twice as long and network installation is not convenient for me with a single server. If you have a standard set of installation options XenServer and / or many servers, though, it might be wise for you to install XenServer automated manner on the network by PXE boot. Have a look at the following links:

Ok, so my bootable flash drive in hand, I can now go through the install XenServer. Most of the installation options are trivial (EULA, media control, password, networking, time zone, etc.); however, it is important to note the ability to enable thin provisioning. This should be enabled, which is the default, to configure local storage repository as EXT3 versus LVM and save local storage space. It is also a requirement if we decide later to use the IntelliCache function of XenDesktop Machine Creation Services with shared storage to cache data locally on the VM XenServer and improve performance of the virtual machine while reducing the use network. See pages 21 and 22 of XenServer Installation Guide 5.6 SP2 http://support.citrix.com/servlet/KbServlet/download/27193-102-6607/installation.pdf for additional details on XenServer and IntelliCache.
The installation time took about five minutes for me - less than ten years! Then I connected to the server with iLO to check status and obtain the IP address. Then I connected to XenServer XenCenter to begin importing my standard OS models. My templates are stored on shared storage and include the latest Windows updates, XenServer Tools, and SysPrep application. More information on creating Windows VM models is available on page 28 of the XenServer 5.6 SP2 Installation Guide virtual machine http://support.citrix.com/servlet/KbServlet/download/27189- 102-6606 / guest.pdf.
In the next segment, I'll watch the XenDesktop components installation on a Windows Server 08 R2 VM basis. Until then ...
