nova does not support create a base vm and then doing a local live
migration or restore for memory snapshots to create another vm.
<br>
<br>
this approch likely has several security implciations that would
not be accpeatable in a multi tenant enviornment.
<br>
<br>
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.

<br>
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'.
<br>
<br>
I highly appreciate if someone can provide a tutorial or related
documentation on how to achieve this?
