DETERMINING VIRTUAL ADAPTER ACCESS CONTROLS 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;
initiating, by a control component of a computing environment, sending of one or more requests over a network of the computing environment by an activated virtual adapter, the activated virtual adapter being hosted on a physical adapter of a host system coupled to the network, the activated virtual adapter for use by a guest, hosted by the host system, in performing data input and output, wherein the one or more requests retrieve access control information from the network, the access control information indicative of one or more access controls enforced by the network in controlling access by the activated virtual adapter to one or more network components of the network, and wherein the initiating comprises the control component providing one or more indications to the physical adapter, absent involvement of the guest, that the one or more requests be sent by the virtual adapter;
based on the initiating, obtaining, by the control component, the access control information from the physical adapter; and
determining, by the control component, based on the obtained access control information, the one or more access controls being enforced by the network in controlling access by the activated virtual adapter to the one or more network components.

Abstract
A control component of a computing environment initiates sending of request(s) over a network of the computing environment by an activated virtual adapter. The activated virtual adapter is hosted on a physical adapter of a host system coupled to the network, and is for use by a guest, hosted by the host system, in performing data input and output. The request(s) retrieve access control information from the network indicative of access control(s) enforced in controlling access by the activated virtual adapter to network component(s). The initiating provides indication(s) to the physical adapter, absent involvement of the guest, that the request(s) be sent by the virtual adapter. Based on the initiating, the control component obtains the access control information from the physical adapter, and determines, based on that information, the access control(s) being enforced by the network in controlling access by the activated virtual adapter to the network component(s).

12. A system comprising:
-
a memory; and a processor in communications with the memory, wherein the computer system is configured to perform a method, the method comprising; initiating, by a control component of a computing environment, sending of one or more requests over a network of the computing environment by an activated virtual adapter, the activated virtual adapter being hosted on a physical adapter of a host system coupled to the network, the activated virtual adapter for use by a guest, hosted by the host system, in performing data input and output, wherein the one or more requests retrieve access control information from the network, the access control information indicative of one or more access controls enforced by the network in controlling access by the activated virtual adapter to one or more network components of the network, and wherein the initiating comprises the control component providing one or more indications to the physical adapter, absent involvement of the guest, that the one or more requests be sent by the virtual adapter; based on the initiating, obtaining, by the control component, the access control information from the physical adapter; and determining, by the control component, based on the obtained access control information, the one or more access controls being enforced by the network in controlling access by the activated virtual adapter to the one or more network components. - View Dependent Claims (13, 14, 15, 16, 17)
