Re: [one-users] HOWTO: various questions about open nebula

Title: Thanks

1. Yes, we can have deferred and hot snapshot. Deferred means backup is done when you shutdown the VM, hot means a live snapshot. 2. I haven't tested it yet, but you can manually zip an image. If you saved it as qcow2 and it is empty, file size is small. 5. On a normal install, you need to boot the VMs again on another node if their original node goes down.

Thank you
