Hi,

I am trying to figure out the technology that openstack uses when multiple
VM's having the* same *base image (OS) are provisioned on a physical server.
Does it use as many copy as the number of VM's or does it use the same base
image and then copy on write.

I need to understand the complete details. Can anybody share some details
or point me to some place where I can find the details.

One link I found was
http://www.linux-kvm.com/content/how-you-can-use-qemukvm-base-images-be-more-productive-part-1
but I want to know more details about how it is implemented and what are
the performance issues etc.

Thanks,
Gaurab
