Release Notes for Cisco OverDrive Network Hypervisor 4.0
First Published: April, 2011OL-24765-01Cisco® OverDrive Network Hypervisor is designed to help enable customers to organize their network resources into a flexible cloud infrastructure that integrates the network with their existing IT operational tools and processes. OverDrive Network Hypervisor's network abstraction layer allows customers to provision and deploy numerous individual network components as sophisticated network "containers" across single and multipod cloud deployments much more easily and quickly than previously possible with template- and script-based systems, dramatically reducing network operations costs and the potential for misconfiguration while optimizing capacity utilization and accelerating service delivery.
Network infrastructure can now be virtualized and fully automated in support of cloud service deployments, creating dynamic, automated clouds providing security, partitioning, and access control - the building blocks to provide IT as a service for any class of customer.

After the script file completes, explicitly remove the /var/lib/pgsql directory. The NSVE may now be re-installed.
After initially configuring an instance of a DSC, replace the default services.xml file (found at /usr/share/overdrive/data/DSC-NAME/services.xml) with the following contents:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?><service-config version="1.0"><services><service name="vm"><properties/></service><service name="vlan"><properties><entry key="vlan.policy.management">model_driven</entry><entry key="vlan.policy.discovered">report</entry><entry key="vlan.policy">end_to_end</entry></properties></service><service name="agent"><properties><entry key="agent.coherentRegionSubnet"></entry></properties></service></services></service-config>
Caveats
Please read the following before using Cisco OverDrive Network Hypervisor 4.0.
Long sysname causes problems for the agent (OD2613)
Description: If the sysname of a router is longer than 20 characters, the agent fails to determine that it is in configure mode.
Workaround: Use shorter names, the total system name should not exceed 20 characters
Post install DSC corrections (OD3958)

The property should look like the following:
syslog.files = /var/log/messages,/var/log/overdrive_od-dsc01.logVLAN Numbers and Subnets are misaligned in Cloud Configurator (OD3937)
Description: Create a VPC and a VDC. Notice subnet values wrap and appear under the VLAN numbers, as though both numbers were being displayed in the VLAN column.
Only one VM may be expanded in Cloud Configurator (OD3727)
Description: In the Cloud Configurator, only one VM may be expanded at any time, to view its detailed settings.
Error messages on NSVE startup (OD3940)
Description: When the NSVE is started, the following errors are displayed in the log file. These may be ignored, they do not require any action.
2011-03-21 09:15:10,879 ERROR [impl.Role] Unexpected error defining Role type settings:com.pfn.wirepower.srv.persistence.role.impl.Role.setTokens(java.lang.String)2011-03-21 09:15:10,879 ERROR [impl.Role] Role entity type will not be definedCloud VLAN Limit error occurs when submitting edit with Cloud Configurator (OD3957)
Description: When clicking Update during an edit operation on cloud within the Cloud Configurator, a Cloud VLAN Limit error occurs, and focus is taken to the Advanced tab. This occurs when a default value for the Cloud VLAN Limit has not been set.
Workaround: Change the displayed -1 value in Cloud VLAN Limit to a non-negative number, and click Update.
VM status does not reliably update in Cloud Configurator (OD3725)
Description: In Firefox 3.6.15, a newly created VM shows status as Creating VM..., despite it having proceeded to Powered On state, as shown in vSphere Client.
When another VM is created, the status of the prior VM changes to Powered On.
Workaround: Consult vSphere Client to determine the status of deployed VMs.
Resources are not being disambiguated in the Summary View in Command Center. (OD3717)
Description: In the Command Center, if Include Subdomains is checked in the Summary View, and Filter by Local Resource is chosen, selecting a sub-domain and re-selecting Root domain will result in loss of disambiguation of objects in the Summary View.
Workaround: Unselect and immediately re-select Include Subdomains.
Clouds are not editable in the Cloud Configurator (OD3412)
Description: Domains viewed within the Cloud Configurator show a Clouds listbox along with Add and Delete controls next to it. This listbox and related controls should not be used, as Clouds should only be manipulated via the controls on the top-right of the breadcrumb bar.
