Open Stack

Hi All,

I'm having a few issues with live migration at the moment. This is an openstack train deployed with rdo packages.


1.        when migrating some VMs the migration succeeds but the VM doesn't move and the following error can be found in the nova logs with nothing that seems to correspond in the neutron logs:
2022-09-30 11:04:04.069 716669 INFO nova.compute.manager [-] [instance: c10d1d9e-2baf-4ab5-ba3a-2f60f521aea6] Took 76.49 seconds for pre_live_migration on destination host hv548.nubes.rl.

2.       When migrating some VMs the migration is marked as complete and the VM is moved from the source to the destination hypervisor but nova keeps the migrating state and doesn't update the host or the node fields. The following error is found in nova with no corresponding error that I can find in neutron. The config is the same across all hypervisors.
