Ok. We are using ssh as the scheme. So, using this new variable live_migration _scheme, how do we specify the ssh options like key location, no strict key checking etc ? I don't see it documented anywhere ? Let me reiterate if I am not clear. I want to know how we can use the new variable live_migration _scheme, since it is mentioned that the live_migration_uri is deprecated ? So, if we use live_migration _scheme, then live_migration_uri is no longer needed. Then as in our case, how do we specify the ssh scheme and its uri options ? Hope I am clear ...
so we recently as in this cycle undeprecated live_migration_uri you shoudl just continue to use that. there was an effort a few years ago to remove it but none of the installer every used the alternate options and our concenous at the last ptg is that having seperate config options instead of one that is effectivly a direct passthough to libvirt is adding more technially debt and maintance burden then the ux improvement it promised. so my recommendataion is avoid live_migration_scheme and keep using live_migration_uri as you do today.

The values for live_migration_scheme are the schemes accepted by libvirt. Thus my recommendation to read the libvirt doc, but sadly, the libvirt page on migration, https://libvirt.org/migration.html, doesn't say much about the migration URIs. Perhaps you need to read the source code for more clarity.
A better place might be Redhat; such as https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm... .

Appreciate your response. I would like to know what are all the valid values for live_migration_schema variable ?

Check the section on live_migration_uri in https://docs.openstack.org/nova/latest/configuration/config.html. For more info, read the live migration documentation for libvirt.

Can you point me to a link on how to use this ?
Thanks

Documentation says "It is not recommended that you change this unless you are very sure that hypervisor supports a particular scheme". In other words, if you don't know possible schemes, leave the config option alone.
Having said that, a few examples of schemes can be found in the documentation for live_migration_uri.
