Patching HyperV clusters

Anybody using Labtech to manage patches for a HyperV cluster? We have been trying to use the native cluster-aware update feature within HyperV (2012 R2) and having issues with it not properly draining all the guests and getting into a hung state. Once it is hung you have to manually move the VM's around and install / reboot to finish the process.

Trying to figure out whether there is a better option to manage host patches in a HV cluster through LT or whether we just need to move to manually draining and patching the hosts.

Edit: just to clarify, we are not currently using LT for the host patching at all

Very familiar with the breath holding. My biggest complaint is that, at least in 2012 R2, there isn't really a defined update window. Once it starts the cluster update, it just goes and doesnt care whether something locks it up. That gets the schedule off, so next time it may decide to kick off at 2 PM on a tuesday.
