Good m/d/n guys, wanted to put idea through you before trying to implement this. So afaik LVM snapshots basically don't take any "real" space on hard drives. I'm using KVM virtualization on my hosts and let's say i create an LVM volume for my linux VM, then install it properly, shut it down and take LVM snapshot of it. Basically i've just cloned it (LVM2 snapshots are r/w). I feed it to KVM and that's it? Can i snapshot this volume N number times and get N number of VMs that take zero actual space on actual hard drive? And when cloned VMs start writing, they will be actually writing only diffs from "master" VM. This looks like an interesting idea to manage a lot of "template" VMs while saving huge amounts of disk space. Or maybe i'm just inventing the bicycle. What do you think? Is this possible? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos-virt/attachments/20120426/03d69858/attachment-0005.html>
