ASCERTAINING CONFIGURATION OF A VIRTUAL ADAPTER IN A COMPUTING ENVIRONMENT
First Claim
1. A computer program product, comprising:
- a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising;
activating, by a control component of a computing environment, a virtual adapter hosted on a physical adapter of a host system of the computing environment, the virtual adapter for use by a guest of the host system in performing data input and output, wherein the control component is separate from the host system, and the activating comprises the control component providing a request to the physical adapter that the virtual adapter be activated;
based on activating the virtual adapter, obtaining, by the control component, configuration information of the activated virtual adapter from the physical adapter, the configuration information generated based on the activating; and
ascertaining, by the control component, a configuration of the activated virtual adapter based on the obtained configuration information, wherein the activating activates the virtual adapter absent involvement of the guest.

Abstract
A control component of a computing environment activates a virtual adapter hosted on a physical adapter of a host system of the computing environment. The virtual adapter is for use by a guest of the host system in performing data input and output. The activating activates the virtual adapter absent involvement of the guest. Based on activating the virtual adapter, the control component obtains configuration information of the activated virtual adapter from the physical adapter, the configuration information generated based on the activating. The control component ascertains a configuration of the activated virtual adapter based on the obtained configuration information.
