[openstack-dev] Nova Live Migration issue

Can you confirm that it's no longer running on the source node and only running on the destination node?

What's your libvirt version?

Possibly the libvirt monitor lost connection and didn't complete the post-migration which would update the db. As Nikolay suggested, the libvirt.log would tell more, good if it also had debug turned on.

Hi!
Can you show libvirt logs?

Hi all
I'm following the below link for VM migration from one compute node to the another from the controller node using devstack ..

http://www.mirantis.com/blog/tutorial-openstack-live-migration-with-kvm-hypervisor-and-nfs-shared-storage/
I'm able to migrate the instance from one compute node to the other compute node using the below command.

nova live-migration b33b23f8-4510-4ed3-8cd1-2d68c8186e40 salaria1
The instance is able to migrate properly and that i have confirmed using the sudo virsh list command over the newer compute node.

However the problem is when i type nova list at the same time.The status of instance is stuck at migrating and does not changes even after some time.
Moreover when i type nova show <instance -id> command,the old host of the instance is reflected instead of the new one.
Please help regarding this.
Thanks
Abhishek Jain
