XenServer 6.x and 7.x have been end-of-life and are unsupported. Customers still using these versions will see host connections no longer functioning when used with Citrix DaaS and Citrix Virtual Apps and Desktops (Version 2411 & later).

Customers should upgrade their Xenserver to a supported version in order to receive continuous support. The latest supported hypervisors for Citrix Machine Creation Services (MCS) and Citrix Provisioning Services (PVS) are listed in CTX131239.
