Enable Snapshot with KVM on CloudStack

How to enable Snapshot with KVM on CloudStack

If you have chosen KVM as your hypervisor in CloudStack then you probably know that Snapshot is not supported by KVM, only VMware and XenServer. This is refering to Snapshots which capture state of the machine much like a VMware Snapshot.

What is supported is Volume Snapshot which is basically a snapshot of individual volumes. A copy of your volume is backed up to secondary storage. It does have some limitations of course, you can not just roll back to this backup.

But before you can use Volume Snapshot you will have to do a couple of things.

Logon to CloudStack and from Global settings select kvm.snapshot.enabled set it to true and restart the management server (kvm.snapshot.enabled = true)
