@borzel Thanks. So which PV drivers and Agent should I use for the time being?

@borzel Yes, I have the Xen PV drivers installed instead of the Citrix PV Drivers. I have noticed that any VMs where the Citrix agent and Citirix PV Drivers (on server 2012 R2) have been replaced will no longer Migrate to other Xcp-NG hosts. Even with the test-signed drivers and Xcp Agent, VMs will no longer migrate. Is there something I am missing here?

It doesn't work on Windows 7 or Server 2008 R2 for me.
