We are conducting a high availability test where we simulated a scenario with one host down in the cluster. After bringing the node down, we attempted to migrate a VM that was running on the affected node. However, the migration failed.

Cold and live migration are functioning correctly, but they do not work in a node failure scenario.

Can you please suggest.

Please find the logs below.

Hi @bwinfra 👋

Welcome to the OpenNebula Forum! 😃

Thanks for sharing with us the VM logs, could you tell us the datastore driver (SSH, LVM, Ceph…) you are using in your datastores?

Best,  
Victor.
