From controller, this command is saying 4.0.0:
$ openstack --version openstack 4.0.0 Is this one what you are looking for? Currently using Debian native openstack deb packages for this train release. On Fri, Sep 10, 2021 at 2:39 PM Thomas Goirand <zigo@debian.org> wrote:

This is Openstack train release. Nova live migration is extremely painful to deal with. Everytime we complete a live migration, nova-compute service on the source host would still be up and runnning, but it would always fail to further increment the report_count database field in nova database, host heartbeat purpose, thus controller would think the hypervisor host failed via its is_up() function checking on report_count and updated_at fields iirc. So we end up having to manually migrate one vm at a time, then restart service, then manually migrate the next vm ..
Any ideas? I already tried setting debug=True for nova.conf even for database tracing, but thus far I could not find any obvious error message. Each time the live migration (no shared storage) would succeed, but each time we will have to restart nova-compute service. This is so bad ..
Any suggestions on this would be highly appreciated.
Thanks, Hai
Hi,
I experienced the same kind of trouble with Nova as well, but this seems to be fixed in the more recent versions. What is the exact point release that you're running?
