Re: KVM Live Snapshots


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?

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"
