New root volume from snapshot
Hello everybody,
is it possible generating a new root volume from a snapshot created by
the root volume, and then assigning it to the same VM as root disk,
deleting the old one?
What I'm trying to explain is a way to operate similar to the hypervisor
snapshot, using the new volume (considered as a backup) as substitute of
the old volume.
Thanks in advance,
Gaspare

After creating the template try this API.
http://localhost:8096/client/api?command=restoreVirtualMachine&virtualmachineid=<vm id>&templateid=<template id>

You can create template from this snapshot and then restore the vm from
this new template id.
Internally it will discard the old root volume and start the vm with a new
disk from this new template
I think this is possible in 4.2. Give it a shot and see how it goes :)

I am also interested in this, using snapshots as a 'last resort backup' or
a simple fallback is something that I think people would find very useful,
without having to remake VM instances.
