Hi, I've been using KVM on Linux (ProxMox VE) for some years and was interested to try it out on SmartOS as wanted to use KVM + ZFS (although newer versions of ProxMox do support ZFS on Linux). Using qcow2 files on linux, and VHDX files on Hyper-V, you can create differencing disks so that you have a single 'parent image' which is shared between all of your vm instances (saves a lot of space as your obviously only storing changes for each vm).
I created a custom KVM image from a sysprep'd Windows Server 2012 R2 x64 vm and imported it locally as in the wiki. From that I was able to generate new vm instances but I assume that the zvol created for each new instance is not a clone of the original zvol (from the golden image) and thus each new vm is getting a copy of the whole original zvol? I'm just interested to know if there is a method using a cloned snapshot of the original zvol that means I can save all this duplicated space? or maybe I am just misunderstanding what imgadm actually does? PS: I can't really afford the memory to enable dedup on the zones pool. Many thanks and sorry for being a novice...
