Issue: The XenServer (annual or not-for-re
sale) license has expired. What is going to happen?
Resolution: If the license on a XenServer host expires while the system is still running, all active virtual machines continue to run as long as the host system is not disrupted or rebooted. However, new virtual machines cannot be launched.
Q: The XenServer (annual, not-for-resale, trial) license has expired. What is going to happen?
A: Upon license expiration, a XenServer host reverts back to the XenServer Express Edition feature set. If the license on a XenServer host expires while the system is still running, all active virtual machines continue to run as long as the host system is not disrupted. However, new VMs cannot be launched. If the host system is disrupted (through a power failure, system restart, and so on), XenServer reverts to Express Edition-level functionality upon restart.
