Troy, yes we are using provisioning services as well, two balancing provisioning servers to be exact. We did have an issue with those servers earlier in the month where Veeam backups were causing one of them to go offline until we restarted the stream service but that has been fixed. Our users aren't going offline, but they get their screen grayed out and says the session is disconnected. I've thought about extending the timeout timer so that while the sessions may pause for 10 seconds it wont time them out. Thanks for looking into it Troy, also glad to see you haven't burnt yourself out of the forums yet!
Tom, that was my thought as well. I suppose I should go to the switch stack to see if there is any bandwidth issues on the switch while vMotion is going on. In theory it would be a good excuse to separate the traffic now anyways to move to a more acceptable networking best practice.
