Hello Abhishek, Did you check on the source node whether the instance is still running or even defined (virsh list -all). This is because nova notices that the migration is completed when the VM in the source is gone and then triggers the post-migration.
IIRC, there's a bug in 0.x libvirt where the destination qemu disconnection is not picked up by the source libvirt, causing nova migration thread to wait. I don't know if libvirt 1.x works with nova properly yet.

I'm using below libvirt version .. libvirtd (libvirt) 0.9.8 Actually I will not be able to present the libvirt logs due to setup problem.I'll send logs as soon as possible. Please let me know if any thing needs to be taken care in libvirt during the configuration On Wed, Apr 2, 2014 at 3:00 PM, Parthipan, Loganathan <parthi...@hp.com<mailto:parthi...@hp.com>> wrote: 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.

Skype: dark_harlequine1 2014-04-02 11:55 GMT+04:00 abhishek jain <ashujain9...@gmail.com<mailto:ashujain9...@gmail.com>>: 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.
