One of the things that Xenserver, still lacks is decent patch management. VMware solved this in ESX3.5/VC2.5 with the “update manager” which is an awesome tool for updating your ESX Hosts. (Yes it can be used for Windows/Linux and applications, but it needs to be refined in my opinion.) Patching Xenserver is a manual job, but not for long. Citrix just announced a new feature for the upcoming Xenserver release, pool-wide patchmanagement.

Pool-wide patch management has been integrated into the product, and, in conjunction with a wizard in XenCenter, will allow you to:

• Check the Citrix XenServer website for updates
• Download any pending updates to your XenCenter system
• Choose which servers in your managed pools you wish to apply the patches to
• Put each server in maintenance mode (with their VMs kept online on another server via XenMotion)
• Apply the patches
• Bring the server back online and move VMs back to it automatically

All in a single guided process.

There should be a beta available soon. It’s good to see Citrix is bringing Xenserver up to speed. This competition/rivalry will eventually make all products better! Read it at the source.
