This task is listed in 1.3 Plan:
Create template from img file (lvroyce)
Royce will let user create a template from img and then use this
template to create a new VM

They are different.
I means "create image from VM" not "create VM from image"
Not sure you have try the glance of Openstack.
Users can create VM from image in glance.
Li Yong install a Openstack.
Mark, royce and I have get agreement, we should create VM from an image,
it is a base function of a VM manage tool.
But do we need to support a same concept of Openstack glance?
As I have comment in the the follow url.
We should support 3 kinds of image.
One is local independent image, we can upload this kind of image.
One is remote image, kimchi can download from remote URL.
Another are the disk devices of VM.
It maybe a serious snapshot with a base image. So we should merge all
these snapshot to the base image.
It maybe also a physical disk. we maybe need to convert it to file image.
Also Openstack support image initialization.
When we create a VM from a base image. we can configure it before VM start.
such as if it is a static IP in the image, we should change it before VM.
There seems 2 kinds of method.
One is libguestfs.
Another is an attached new extra image with a script in it. Not well
know it. need to talk with our Openstack developers.
