For independent developers and ISVs Sun xVM Ops Center provides an SDK and public APIs. The APIs allow third party systems management vendors to integrate with xVM software. The APIs are ideal for ISVs to manage and control xVM software.

There are two sets of APIs:

  • JMX-Remoting API &
  • WS-Management API: This is the most likely API that third parties would use.

The functionality exposed via the APIs provides:

  • Discovering resources on the network
  • Provisioning OS and firmware to servers
  • Patching OS
  • Managing Sun xVM Servers
  • Managing virtual pools
  • Managing and migrating guests
  • Managing datacenter
  • Managing virtual image libraries
  • Monitoring OS and servers

The SDK contains the following:

  • Complete Javadocs of public APIs. The Javadocs include mapping of WS-Management queries and responses.
  • Functional examples demonstrating how to use the APIs. 
The SDK requires Java 6.

VirtualBox 2.1 was released a few days ago. One of the features that improved a lot has been Networking - setting and actual performance.

Previous to 2.1 release, simplest way to setup networking was to go with default setting of NAT. Though it worked, it had its own problems, For example Ping never worked, performance suffered since every packet had to be NATed. HostInterfacing was way complicated on all the plateforms except for Solaris.

The simplicity of setting Host Interface is now available on all the platforms (not just Solaris). Host interface uses the network connection of the HOST machine with out overheads.

To set it up, launch VirtualBox 2.1.

Click on "Settings" as shown below:

It pops up the following window where select "Network"


Select Adapter Type to be either PCnet Fast II or III if you do not know the one available on your machine.

Select Attached To Host Interface  ==> to make use of Host machines interface

And select an Host Interface from the list of Host Interfaces available.

That's it. You are done and you will have a very good network performance
