Example of an RSpec request for two nodes virtualized on pcs which may be running more than one experiment.

You may wish to use virtualization to create a sliver on a shared node which splits a physical resource among multiple experiments. Here is a request which creates a shared node. Currently, shared nodes use OpenVZ:

RSpec V2 Example

<?xml version="1.0" encoding="UTF-8"?>
<rspec xmlns="http://www.protogeni.net/resources/rspec/2"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.protogeni.net/resources/rspec/2
                           http://www.protogeni.net/resources/rspec/2/request.xsd"
       type="request" >
  <node client_id="my-node"
        exclusive="false">
    <sliver_type name="emulab-openvz" />
  </node>
</rspec>

RSpec V0.1 Example (Deprecated)

<rspec xmlns="http://www.protogeni.net/resources/rspec/0.1"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.protogeni.net/resources/rspec/0.1
                           http://www.protogeni.net/resources/rspec/0.1/request.xsd"
       type="request" >
  <node component_manager_uuid="urn:publicid:IDN+emulab.net+authority+cm"
        virtual_id="shared1"
        virtualization_type="emulab-vnode"
        virtualization_subtype="emulab-openvz"
        exclusive="0">
    <node_type type_name="pcvm" type_slots="1"/>
    <interface virtual_id="control"/>
  </node>
</rspec>

When logging onto this nodes, you have to ssh to the correct port. This is returned in the manifest (example).
