Error (10698)
The virtual machine (x) could not be live migrated to the virtual machine host (y) using this cluster configuration.
Recommended Action
Check the cluster configuration and then try the operation again.
We got the above error on one of our server in our 4 node Hyper V 2012R2 Cluster after having the node down to do the latest MS updates Dec 2014.
The fix in the end was to on the node that we could not migrate to:
Navigate to C:\Windows\System32\GroupPolicy\Machine on the server in question
Delete the file “Registry.pol“ or rename it if you prefer (example Registry.renamed)
Then restart the Hyper-V Virtual Machine Management service (NOTE! THIS WILL RESTART ANY VM's ON THIS NODE) in our case the Node was Empty since it had just been down for maintenance.
A new Registry.pol file will be created
I found the fix here http://jack-brennan.com/hyper-v-live-migration-error-applying-changes/ but it took some searching, so wanted to re-post here the help out others with the same issue.
If anyone knows why this fixes the issue I would love to know!
