Hello team,

I am unable to migrate/live-migrate VMs from one compute node to another. Please note that all the commands were executed using root user credentials.

Command executed to migrate from ComputeA to ComputeB:

openstack server migrate c408e2ec-f555-4bd6-8d4d-52186877cd6e --live ComputeB

After this point, I don't get any error. Checked in logs and I couldn't see any error related to migration as well.

Please let me know what could be wrong here?

Update #1:

Able to see this in nova-compute.log on computeA:

2018-01-11 15:12:22.160 32681 ERROR oslo_messaging.rpc.server InvalidSharedStorage: defnet2 is not on shared storage: Live migration can not be used without shared storage except a booted from volume VM which does not have a local dis

If that is the case, can migration be done without --live option? and how?
