Availability of Features
SR-IOV is not available for virtual machines configured to use Network I/O Control version 3.
Upgrade Network I/O Control to Version 3 on a vSphere
Distributed Switch
If you have upgraded a vSphere Distributed Switch to version 6.0.0 without converting Network I/O
Control to version 3, you can upgrade Network I/O Control to use the enhanced model for bandwidth
allocation to system traffic and to individual virtual machines.
When you upgrade Network I/O Control version 2 to version 3, the settings from all existing system
network resource pools that are defined in version 2 are converted to constructs of shares, reservation,
and limit for system traffic. Reservation for all converted system traffic types is not set by default.
The upgrade of a distributed switch to version 3 is disruptive. Certain functionality is available only in
Network I/O Control version 2 and is removed during the upgrade to version 3.
