Hi,

We are using Openstack Rocky . We are observing internal network is using while we do live migration. our internal network interface is 1G. So interface getting full and migration never getting complete. 

(nova server-migration-list ) 'Remaining Memory Bytes' increasing and decreasing but not getting completed. 

We have 10G interface for public/external network. I have tried following solution but no luck. still using internal network

https://specs.openstack.org/openstack/nova-specs/specs/mitaka/implemented/split-network-plane-for-live-migration.html

Some Information:

[DEFAULT]

my_ip = Internal_network_IP

[libvirt]

live_migration_uri=qemu+ssh://nova@%s.external/system?keyfile=/var/lib/nova/.ssh/id_rsa&no_verify=1

Please let us know if any further information is required.

Please advice us if we can solve the issue.
