How to replace PCIe Direct I/O cards assigned to a OVM guest domain
(Doc ID 1684273.1)

Information in this document applies to any platform.
PCIe endpoint devices assigned to a guest domain do not support hotplug operations which leaves two options for card replacement:
1. Cold service with the PCIe endpoint removed after shutting down the whole platform
2. Hotplug after reassigning the PCIe endpoint device to the corresponding root domain
The following instructions apply to option#2 where we want to reassign the device to the root domain for hotplug. It is important to note this option still requires domain downtime, however this is limited to the impacted guest domain and root domain so it is useful in environments where customers have multiple domains deployed on a single platform. For more information about about OVM, PCIe endpoint devices look at:
