I have recently created one Windows Server 2019 VM at Hyper V 2012 R2 host. I see below events always. How could I fix it?

    Hi,

    As far as I'm concerned, the error message may due to the Windows Server 2019 VM version is too higher for the Windows 2012R2 host. Server 2012 R2 has no knowledge of Server 2019, nor the version of the Integration Components that it would have.

    It's recommended to upgrade the Hyper V host System version, so they can have better compatibility.

    Thanks for your time!
    Best Regards,
    Anne

    I suspect same thing what you said. I verified some other server 2019 and 2016 which is running at different-different Hyper v 2012 R2 host and I observed same events there too. Since those VMs are running fine since years so I think I can ignore it. thanks for your help
