I assume you're talking about a situation where there is an initial VM image, and then to clone the machine, the customers copy the VM, correct? If that is correct, have you considered ZFS cloning instead? When I said dedup wasn't good for VM's, what I'm talking about is: If there is data inside the VM which is cloned... For example if somebody logs into the guest OS and then does a "cp" operation... Then dedup of the host is unlikely to be able to recognize that data as cloned data inside the virtual disk. > Our customers have the ability to access our systems engineers to design the > solution for their needs.
