The dynamic SR-IOV feature removes the following static SR-IOV requirements:
Root domain. Initate a delayed reconfiguration on the root domain, create or destroy a virtual function, and reboot the root domain
I/O domain. Stop the I/O domain, add or remove a virtual function, and start the I/O domain
With dynamic SR-IOV you can dynamically create or destroy a virtual function without having to initiate a delayed reconfiguration on the root domain. A virtual function can also be dynamically added to or removed from an I/O domain without having to stop the domain. The Logical Domains Manager communicates with the Logical Domains agent and the Oracle Solaris I/O virtualization framework to effect these changes dynamically.
