Hi there,

I've successfully installed openstack with rbd volumes backend but experiencing issues with live migration. I'm getting "Failed to compute_task_migrate_server: node01is not on shared storage: Live migration can not be used without shared storageFailed to compute_task_migrate_server: node01is not on shared storage: Live migration can not be used without shared storage" error. I guess it should be addressed soon by https://review.openstack.org/#/c/91722/.

But even though I've failed with block migration. Getting "NoBlockMigrationForConfigDriveInLibVirt: Block migration of instances with config drives is not supported in libvirt." I'm trying to migrate default m1.tiny flavor instance

$ nova flavor-list 

+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name      | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| 1  | m1.tiny   | 512       | 1    | 0         |      | 1     | 1.0         | True      |

if makes sense.

Any thoughts of how to set up live migration with rbd storage backend properly would be appreciated.

Thank you,

Pavel

Do you have a link to the bug report for that patch?

you have to disable config drive without coming patches that fixes the issue. right now using nova trunk, you should be able to live migrate instances no matter config drive is enabled or not.
