As I’m discovering the CLI options I can revert to for scripting automated jobs for the XenServer 5.5 environment, I wanted to check out the new PowerShell Snapin provided by Citrix. After downloading and installing the XS-PS Windows installer I discovered that the PowerShell cmdlets were only installed for the PowerShell (X86) console and were not installed for the 64-bits console.
Fortunately for me a solution is mentioned on the XenServer SDK download page
In order to use the cmdlets in the 64-bits PowerShell Console, all you need to do is run the following command after the msi install in a command box:
C:\Windows\Microsoft.NET\Framework64\v2.0.50727>InstallUtil.exe "c:\Program File
s (x86)\Citrix\XenServerPSSnapIn\XenServerPSSnapIn.dll"
