I want boot instance from volume snapshot in cmd, but I never found it in `openstack server create --help` and https://docs.openstack.org/nova/latest/user/launch-instances.html.

Could I do it in cmd? I saw that this can be done on horizon

I'm not clear exactly what you're looking for, but the `openstack server create` subcommand has several related options. If you want to boot from a snapshot image use --snapshot, for booting from a server image with a new volume backing use --boot-from-volume, and to boot from an existing volume which contains a server snapshot use --volume: https://docs.openstack.org/python-openstackclient/latest/cli/command-objects... I think you may be asking about the --volume option? -- Jeremy Stanley
