Hyper-V live migration failed after configuration change

If you change the virtual host configuration (for example, add another virtual NIC) using Hyper-V MMC after the virtual host is "HAed", live migration would fail. To resolve this, remove the VM from the cluster and add it in again.

After some research on the Internet, I realised that you must not use Hyper-V MMC, use the "Setting" button in the Failover Clustering Manager instead. (Click below to enlarge)


  1. I was facing same problem.And to my amazement the issue is resolved once I removed the VM from the cluster and added it in again.Thanks for the tip too.

  2. Thanks for thwe tip, you solved a problem for me that's been driving me crazy! Lol
