[libvirt PATCH v3 12/21] api: add virNodeDeviceDefineXML()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With mediated devices, we can now define persistent node devices that
can be started and stopped. In order to take advantage of this, we need
an API to define new node devices.
