  1. Hyper-V CimSession Caching Bug

    The Server 2016 Hyper-V module caches CimSessions, presumably to make queries for related entities faster. The problem is that it also caches explicitly provided CimSessions that it does not own the lifetime of. So, if you ever use a CimSession with a Hyper-V cmdlet, then close that session, Hyper-V will try to use that disposed CimSession for any future interaction with the host in question. This is wrong, you can't cache objects with a lifetime you don't control without at least handling the case when that lifetime has been ended by the actual owner of the object.

      • VSS Hyper-V VM bug

        There is a bug, uncovered when using Veeam backup software which they describe as -

        "Application-aware processing of Active Directory domain controllers running on guest OS other than Windows Server 2016 fails with the “Failed to create VM recovery checkpoint” error (32770). This is a Hyper-V 2016 issue that Microsoft is planning to address in the future update."

        Any news on a fix for this would be great.
