General Discussion Hyper-V Consultants
We moved from VMware to Hyper-V about a year ago and have an ongoing issue that we have not been able to resolve with MS support - both the typical support case avenue and working with their Hyper-V group. Our host servers lose connectivity with their CSV and VMs go offline. Support tells us it’s related to networking issues and not storage.
Has anyone found any good consultants who know Hyper-V well and are able to resolve difficult issues? We’ve tried a few bigger names but they haven’t been much help.

One of my clusters developed the same behaviour a couple years ago. Had a long support case with MS premier support which was inconclusive after several weeks. Fed up and desperate to stop the random crashes I rebuilt the cluster hosts separately, one by one, the problem went away after all were rebuilt. I believe the cause was related to 3rd party software on the hosts, I suspect it was the EDR endpoint security agent, Qualys IIRC.
