XenServer 7.1 Long Term Service Release (LTSR)

The Long Term Service Release (LTSR) program for XenServer provides stability and long-term support for XenServer releases.

The XenServer product lifecycle strategy for Current Releases (CR) and Long Term Service Releases (LTSR) is described in https://www.citrix.com/support/product-lifecycle/milestones/xenserver.html.

A XenServer LTSR is currently available for version 7.1. Cumulative Update 2, released 12 December 2018, is the most recent update to the 7.1 LTSR. If you are new to the LTSR program and did not deploy the initial 7.1 LTSR release, there is no need for you to install it now. Instead, Citrix recommends that you begin with 7.1 Cumulative Update 2.

Important

In December 2019, version 9.x of the Windows I/O drivers (xenbus, xenvif, xenvbd, xeniface, xennet) were made available through Windows Update, for example, xeniface 9.0.0.11.

The verson 9.x drivers remove the quiesced snapshot capability. This capability is also removed from support in Citrix Hypervisor 8.1 and later. For more information, see Citrix Hypervisor 8.1 Deprecations and removals.

To continue to use the quiesced snapshot feature with Windows VMs hosted on XenServer 7.1, do not update to the 9.x drivers and retain your current 8.x version of the Windows I/O drivers.
