    This is a fairly simple question, and I'm hoping the answer is fairly simple too.

    I have a straightforward 3-node failover cluster: the servers are running WS2019, and the 30+ VMs are running a mixture of Windows Server, Red Hat Enterprise Linux, and Ubuntu.

    The Linux servers live-migrate flawlessly.

    The Windows servers will NOT live-migrate; they throw a 1155 error.

    Any thoughts?

    Thanks!

    Hi,

    Please check if the VM has any checkpoints in it? If so, delete the checkpoint and live migrate it again.

    Hi Matt,

    1. Please check if there's checkpoints on the VMs failed to live migrate, if yes, please try to remove the checkpoints and do live migrate, check if it could work.

    2. Please check the network settings for the live migration, do you use Broadcom network cards, and please check if we enable VMQ, if yes, please try to disable VMQ for the live migration network.

    Thanks for your time!

    Best Regards,

    Anne
