How to Convert VMware Virtual Machines to XenServer Virtual Machines

This article describes two methods to convert a VMware virtual machine to a XenServer virtual machine. The first method is to export and import it in an Open Virtualization Format (OVF) package. The second method is to export and import its disk images. It is preferable to use the first method because it retains many Virtual Machine properties and is simpler for a Virtual Machine with multiple disk images.

Note: This article is for XenServer 6 onwards. For XenServer 5.6 and earlier, refer to CTX116603 – How to Convert VMware Virtual Machines to XenServer Virtual Machines 5.6 and Earlier.

Preparing VMware Virtual Machine

  • Power on Virtual Machine and login.
  • Uninstall VMware Tools.
  • Delete/uninstall any unnecessary data, drives, partitions, and applications.
  • Shutdown Virtual Machine.

Exporting VMware Virtual Machine to OVF Package

The following VMware products support OVF package export:

  • VMware vSphere
  • VMware Infrastructure
  • VMware Workstation
  • VMware OVF Tool
  • VMware vCenter Converter
  • VMware Studio

Note: The following instructions are for VMware vSphere.

XenDesktop and Provisioning Services on vSphere 5

Scott Cochran wrote a good blog post on the Citrix blogs which this is the beginning.

I want to preface this post by saying if you are not interested in any backstory just skip down to the summary section for a wrap up…

Coming from a consulting background I learned the hard way that you always have to check the compatibility of all components in a project.  Since VMware released vSphere 5 many people found out the hard way that Citrix Provisioning Services (PVS) was not supported on VMware’s latest hypervisor platform.  People without in-depth knowledge of the Citrix solution stack may have read XenDesktop 5 was supported on vSphere 5, but in reality that only meant when using Machine Creation Services (MCS).  This forced companies to have to make some hard decisions.  You could either go down the route of using MCS with vSphere 5, or go with Provisioning Services on vSphere 4.x.  Hopefully most customers consulted with their trusted Citrix advisor prior to making this

vSphere 5 License Overview

Hi guys,

Found this post about the new vSpehere licence model.

Here a piece of the post.

“Before you upgrade to VMware vSphere 5, run the tool below to learn how much vRAM you are currently using and how much you are entitled to under vSphere 5 licensing.

Because vSphere 5 licensing is based on a per-processor basis with vRam entitlements, you need to make sure all license keys you have purchased are entered into vCenter Server.

The following vRAM entitlements will be given per license type: Continue reading “vSphere 5 License Overview”
