This is a demo of a third party extention that was never upstreamed. nova does not support create a base vm and then doing a local live migration or restore for memory snapshots to create another vm. this approch likely has several security implciations that would not be accpeatable in a multi tenant enviornment. we have disucssed this type of vm creation in the past and determined that it is not a valid implematnion of spawn. a virt driver that precreate vms or copys an existing instance can be faster but that virt driver is not considered a compliant implementation. so in short there is no way to achive this today in a compliant openstack powered cloud.

Hi,
I was looking for a way to provision and connect to VMs within a few seconds and ended up in the OpenStack Summit demo on 'OpenStack Virtual Machine Quickly Available in One Second'.
I highly appreciate if someone can provide a tutorial or related documentation on how to achieve this?
