RBD and live migration
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
