this approch likely has several security implciations that would not be <br>
accpeatable in a multi tenant enviornment.<br>
<br>
we have disucssed this type of vm creation in the past and determined <br>
that it is not a valid implematnion of spawn. a virt driver that <br>
precreate vms or copys an existing instance can be faster but that virt <br>
driver is not considered a compliant implementation.<br>
<br>
so in short there is no way to achive this today in a compliant <br>
