We are using a Nutanix cluster though this could just as easily apply to VMware. We use RDP sessions from a Windows 2012 server to thin clients running either Windows 8, 10, or HP ThinPro to provide HMIs in an industrial setting. Currently I have to schedule maintenance on our (infrequent) down days as my operators freak out if the RDP sessions drop even momentarily. We have noticed that migrating VMs often causes these sessions to drop.
Is there a way to configure either the thin clients or the server so that the connections could weather the perhaps several millisecond-long outage as the VM migration completes?
