There are two main ways to save your changes to virtual machines in Abiquo, which are to create:

  • instances
  • persistent virtual machines

Making Copies of System Disks as Instances

An An instance is a  is a snapshot copy of  of a virtual machine machine system disk. An instance does not save the virtual machine configuration from the virtual machine.

In an Abiquo datacenter, in the Apps Library, instances share Abiquo creates instances with a copy of the same template definition as the original master template the virtual machine was originally deployed withfrom. 

In public cloud regions, instances are independent of the original master template.

 

When you create an instance of a virtual machine, the virtual machine disk is saved but the virtual machine definition is not savedWhen you add the instance to a virtual appliancemachine definition, with values such as CPU and RAM, is copied from the master template.  When you create a virtual machine (in a virtual appliance in a virtual datacenter), the saved disk and the original definition of the instance's virtual machine definition from the Apps Library are used to create a new virtual machine. You can edit the instance template and change the virtual machine definition for use in virtual machines that you create from that time onward. Changes in the Instance template virtual machine definition will not affect the Master template.

If you know that you will need to use a virtual machine in a datacenter over a period of time and perhaps even undeploy the machine and then deploy it again at a later date, then you should can create a persistent virtual machine.
