Hello!

Migration unattached volumes between cinder pools works well. Trying to migrate attached volume between cinder pools and getting this problem:

Have you checked if "attached" volume migration in cinder is still supported yet?

No-one has answered this, I am having the same problem. Within the year since asking, have you solved the problem?

Few things needs to set:

1) file -> /etc/nova/nova.conf (controller & compute1, compute2) live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE

2) file -> /etc/sysconfig/libvirtd on compute1, compute2 LIBVIRTD_ARGS=”–listen”

3) file -> /etc/libvirt/libvirtd.conf listen_tls = 0 listen_tcp = 1 listen_addr = "0.0.0.0"

4) netstat -lntp | grep libvirtd

[root@controller ~]# . demo-openrc [root@controller ~]# nova live-migration 12 compute2 ERROR (Forbidden): Policy doesn't allow os_compute_api:os-migrate-server:migrate _live to be performed. (HTTP 403) (Request-ID: req-e7e57b87-cad1-4e4c-9eb3-d76e8 5651b67)

Note - source admin-openrc before migration.

He is doing a cinder migration, not a nova live migration. 2 different things.
