[one-users] [OCA JAVA] Allocate VM from XML template

[Carlos Martín Sánchez]

Hi,

To create new VMs, you can either:
- create a Template (OpenNebula Template, not the string), and instantiate
it [1]
- directly create a VirtualMachine from the string description template [2]

In both cases, the description string can be in NAME=VALUE format, or in
XML. The core will accept any of them; copied from [3]:


The methods that accept XML templates require the root element to be
TEMPLATE. For instance, this template:

NAME = abc
MEMORY = 1024
ATT1 = value1

Can be also given to OpenNebula with the following XML:

<TEMPLATE>
  <NAME>abc</NAME>
  <MEMORY>1024</MEMORY>
  <ATT1>value1</ATT1>
</TEMPLATE>
