How to Shut Down a Virtual Machine which is Unresponsive in the Pending or Amber State in XenServer 5.x:


This article describes how to shut down a virtual machine, which is in a pending state (or amber state), from the XenServer control domain.


You require the following components:

  • Console session to the XenServer control domain
  • Intermediate Linux / XenServer administration skills


Sometimes, when you initiate a shutdown or a reboot from the XenCenter, the virtual machine is in an unresponsive state when it is in the pending state (or amber state), and the task being performed is also in an unresponsive state.

The application appears after a time out that varies and after appearing, the applications behave as expected.

In other cases, the application is started correctly but during scenarios such as execution or accessing different module of the application, this access might take more time to process or fail in some cases.

This behavior occurs when the servers where the applications are published do not have Internet access and these applications have some.NET or Java component certificate that must be verified. If the server does not have Internet access, then the .NET framework or Java component cannot access the website to verify that the digital signatures that are used to sign the binaries for managed applications are valid. Each certificate check has a 15 second timeout in the .NET runtime implementation. Depending on what features are installed, this can add up to a minute of startup time for the application.


To avoid this behavior and resolve the application delay, you must change several options in the Internet properties Advanced tab on the servers, applying a GPO or manually through registry modifications
