Slipstream XenServer Supplemental Packs
Citrix recently released new version of XenServer a Hypervisor based on Xen, originally a research project at the University of Cambridge. With the new XenServer 6.1 we get live Storage XenMotion (Not Available in Free Edition) to migrate VMs between Hosts and Pools without shared Storage. With this release we also get new version of System Centre Integration Suite and Performance Monitoring supplemental pack.
It is necessary that we update these supplemental packs when ever we update XenServer. In general we provide Install Media of the supplemental packs when asked for while installing XenServer or by using xe-install-supplemental-pack command.
The easy way is to slipstream the supplemental packs to the XenServer Install media and perform the update or installation. Below are simple steps to slipstream XenServer install media with supplemental packs.
1. Copy or extract all files from XenServer install media to a folder. Mine is XenServer6.1
2. Create one folder for each supplemental pack inside above folder. In my case I am using Integration suite and Performance monitoring supplemental packs and created two folders named packages.integration-suite and packages.perf-monitoring following Citrix’s naming convention for XenServer folders as shown in below screenshot.
3. Copy or extract all the files of supplemental packs to respective folders created above.

Missing Windows Server 2012 Management Tools
If you have installed Windows Server 2012 Roles and Features using PowerShell or remote server admin tools or new multi server manager console, you will see that the management tools are missing from the server on which you just have enabled the role or feature. This is because Microsoft has provided more granular control on what is installed on the Windows Server 2012. As an administrator we have choice to include or not to include management tools while installing the Roles and Features we choose.
Below is a comic illustrating the same.

Lighttpd health monitor on F5 Big IP Load balancer
If you are trying to use F5 Big IP LTM (Local Traffic Manager) to load balance webservers running Lighttpd and have configured default http health monitor from F5, you would notice that the F5 would treat the servers as non responsive and mark then down.
This is because the send string in the default monitor is configured as GET /\r\n which is not accepted by few standard webservers like lighttpd.
A simple solution to this problem is to create a custom monitor with the help of default http monitor.

Ubuntu 12.04 has Hyper-V support Built-in
The latest release of Ubuntu 12.04 LTS (Long Term Support) code named Precise Pangolin from Canonical has many new features as in with any new release improving stability and speed. The interesting addition that will excite Microsoft shops and fans is built in support for Hyper-V eliminating the need to install Microsoft Linux Integration Components inside Ubuntu 12.04 when deployed as a VM
As you can see in the above screenshots the kernel version is 3.2 which has Hyper-V IC modules and detects all Hyper-V synthetic devices like NIC, SCSI storage, has mouse integration and supports multiple vCPUs out of the box.
Hope to see other Linux distributions do the same soon.
