Re: KVM Live Snapshots
Simon - thanks for the reminder re VM snapshots - I think you've actually told me in the past as well.
Asai - a VM snapshot remains on primary storage and is there for the purpose of rolling a VM back to a previous timestamp, and it is not available for download.
Volume snapshots are copied to secondary storage for the purpose of downloading by end user - but these are handled on a per volume basis.

Thank you for your responses,
What’s the difference, then, between a "VM" snapshot and a "VOLUME" snapshot? I liked how in XenServer, you could export a whole VM by first taking a snapshot. This was great for disaster recovery backup, is there a way to do something similar in Cloudstack?

> We successfully upgraded to 4.11.1. One of the main reasons we did this was that we thought this would enable us to do live KVM snapshots of running VMs. This doesn’t seem to be the case, though. When I try to snapshot a running VM, I just get the message: "KVM VM does not allow to take a disk-only snapshot when VM is in running state"
