The issue I describe in this blog are related to my XenServer, my lab at home, be very careful with the modification I explain if you plan to make this change in your own environment... As always, do it on a test environment before please ! Since last week and my XenServer @ home crash, I chose to install the latest XenServer version, 5.6 FP1 (more info here) to try out some new features like Intellicache / open vSwitch / VM Protection and Recovery and the self service portal. The installation was as smooth as usual, just one question more than the previous version about the installation of Intellicache. I've been able to reinstall all my VMs, configure everything and check all these new features. The only issue was my file system was running out of space very very very quickly... I didn't understand why at first because I'm not that skilled with XenServer with command line stuff but I needed to find out what was happening. The first place to check when something wrong is going on, are the log files, you can find XenServer logs files here : /var/log , and the size of my log files were huge ! in less than 24hour I had 3 rotations of log on kern.log and messages log files... To buy me some time and allow me to continue to connect to the XenServer with XenCenter, I made some change in the rotation log configuration file /etc/logrotate.conf : I made the following change, rotate value was 20 I changed it to 5, I activated the compression of log file archives. It did give me some more time to work on this weird issue but not enough, in less than 12 hours my file system was full again... XenCenter wasn't able to connect and the xsconsole command line wasn't working as well. The only way to recover the interface was to kill the xapi process and restart it by using : xe-toolstack-restart command line (I needed to free as much space as possible before). Then I've been able to use XenCenter and xsconsole. I got the message bellow after all these troubleshooting stuffs but still no clue why my log files were becoming so big so quickly... Of course I looked the log file and I saw : Ok... I didn't catch everything, I knew it was something about network but I…

If you're used to check the IMA service and verify if everything is running fine on your XenDesktop 4 or XenApp environment, you won't find any IMA in XenDesktop 5. This is one of the huge changes Citrix have done in the new XenDesktop, this is a major change because no more IMA means many things in term of architecture and product functionality. So as I just mention, no IMA in XenDesktop 5 Controller (DDC), which means there is no IMA data store or local host cache (!!!) No more XML Blob, there is no more Active Directory Configuration Wizard or Farm OU, XenDesktop 5 doesn't need Terminal Services any more, everything is stored in a brand new SQL database and there is no support for Oracle or Access. <-- Wow ! These are a big changes right ?  I will explain more the impact of these change regarding what we're used to and the consequences. First thing first, when you want to install XenDesktop 5, you have choice between the "Quick Deploy", "Join existing deployment",  "Desktop deployment" and "Application deployment". You can also notice the installer is simpler than the one in XenDesktop 4 "Quick deploy" option is the fastest way to deploy a fully functional XenDesktop installation. All in one box, Citrix License Server, the DDC, and Database. "Join existing deployment" add a XenDesktop Controller to an existing site. "Desktop deployment" advanced installation for large deployment, to use with Citrix Provisioning Services. Regarding the installation, on the server side, XenDesktop Controller supports Windows Server 2008 and 2008 R2 only, exit Windows 2003. If you want to use the “Quick Deploy” mode, then all components must be on same box, it also assumes SQL Express is installed on same machine. Microsoft PowerShell 2.0 is downloaded during the installation, you will need to manually install PowerShell 2.0 if you don't have internet access. You can use the same License Server as XenDesktop 4 (11.6.1) Desktop Controller – System Requirements Microsoft Windows Server 2008, Standard or Enterprise Edition, with Service Pack 2 Microsoft Windows Server 2008 R2, Standard or Enterprise Edition Service Pack 1 will be supported Microsoft .NET Framework, Version 3.5, with Service Pack 1 Microsoft Internet Information Services (IIS) and ASP.NET 2.0 IIS is required only if you are installing the Web Interface, the License Server, or Desktop Director Controller – Database Requirements Microsoft SQL Server 2008 R2 Microsoft…
