<div dir="ltr">Hi<div><br></div><div style>I think that this very same functionality is supported by OpenNebula. Note that OpenNebula makes a difference between the definition of a VM and its instance. An instance can be updated only on specific ways (e.g. you can add/remove disks through hotplug, in 4.0 you will be able to add/remove NICs or change the *instance* name). However the definition can be freely updated.</div>
<div style><br></div><div style>There are a couple of benefits of keeping the definition and the instance separated. One is being able to update the attributes and create multiple instances of the same definition.</div><div style>
<br></div><div style>So you can:</div><div style><br></div><div style>1.- Define a Template with a given CPU, MEMORY, DISKs....</div><div style>2.- Instantiate the that Template to create a VM</div><div style>3.- (persistent VMs) Shutdown the VM. Update the Template a re-instantiate it. The new VM will use the new attributes.</div>
<div style>4.- (non-persistent VMs) Update the Template and instantiate it. The new VMs will use the new attributes.</div><div style><br></div><div style>IMHO this is equivalent to the functionality referred in your email.</div>
