In openstack, it is possible to migrate a vm. I would like to know if it is also possible to replicate a vm with its current state. If it is not, can we manipulate the migration code in such a way that a VM can be replicated instead of being migrated? I appreciate any suggestion, recommendation, sharing experiences, etc.

You can try to use this tool to replicate VMs. It works with both local or bootable volumes:

It is possible to migrate a VM. You can also 'clone' a VM by creating a snapshot of the instance to be 'cloned' and creating a new instance from that snapshot image.

Thanks for your answer. What about the current VM state? A snapshot can hold the VM state at the time the snapshot has been created. In this way, I need to make snapshot repeatedly in cetarin time slots which is computationally and storage expensive.

Snapshotting vm state is for virtualization platforms like vsphere, ovirt. ... not for cloud platforms like openstack

Yes it is. I just wanna orchestrate replication with the Openstack, exactly the same as migration in Openstack. VM migration is also for visualization platforms, but we have it in Openstack. In fact, openstack orchestrates migration while the main task is done by the hypervisor & virtualization APIs
