If we can control fall back of IntelliCache reads and writes back to the storage then it won't hinder with host maintenance mode and Xenmotion, and I think it helps handling volatile VMs without recreating the root disks. Thanks, Harikrishna On 09-Aug-2013, at 11:39 AM, Prasanna Santhanam wrot

Hi guys, Is anyone concerned about using XenServer 6.2's clone-on-boot feature on CloudStack? With it, we can quickly deploy a huge of VMs from a single golden template. This is amazing for some scenarios. For example: we can allocate a special/dedicated cluster with only one golden template. And
