2) The host computer is started up and the host computer adapter is automatically started, the host computer adapter calls the heartbeat request module to issue continuously-changed heartbeat messages (including host computer names, IP addresses and the like), the heartbeat messages are forwarded to the equipment management agent module through the adapter message forwarding module, and the equipment management agent module updates the state of the host computer into the online state of the equipment and stores the online state of the equipment in a database;
3) The Web front-end page equipment display module is used for sending equipment state query information to the equipment management agent module at regular time, and after the equipment management agent module queries the host machine state information from the database, the equipment management agent module returns the host machine state information such as equipment online and IP addresses to the Web front-end page, and the Web front-end page displays the equipment state for a user to check;
4) A user submits an equipment creating request through a web front-end equipment management view, and request information comprises information such as the number of processor cores of a virtual machine, memory capacity, hard disk capacity, and identifiers of simulated hardware peripheral modules such as various hardware accelerator cards;
5) After receiving the device creation request, the Web back-end device management agent module further forwards the device creation request information to an adapter module of a certain host in the host cluster through an adapter message forwarding module according to a certain load balancing algorithm (such as a consistent hash algorithm comprehensively considering the IP address of the host and the number of created virtual machines);
6) The host machine adapter calls a local machine equipment creating module to create a virtual machine and distributes a simulation hardware peripheral module to the virtual machine according to the virtual machine configuration parameters contained in the received equipment request, then the virtual machine is started, and the details refer to fig. 2;
7) The virtual machine startup self-starting adapter module executes a command (including equipment creation/deletion/control, case execution and the like) message subscription process same as that of a host adapter, and simultaneously calls a heartbeat request module to issue continuously-changed heartbeat messages (including host names, IP addresses and the like), wherein the heartbeat messages are forwarded to an equipment management agent module through an adapter message forwarding module, and the equipment management agent module updates the state of a virtual machine into an online state of equipment and stores the online state of the equipment in a database;
8) The Web front-end page equipment display module is used for sending equipment state query information to the equipment management agent module at regular time, after the equipment management agent module queries the virtual machine state information from the database, the virtual machine state information such as equipment on-line, equipment off-line and the like is returned to a Web front-end page, and the Web front-end page displays the equipment state for a user to check;
9) A user creates a use case on a web front-end page according to an interface provided by a use case management view, or introduces the use case from an external file, the use case management view automatically sends a use case creation request to a web rear-end use case management agent, and the use case management agent stores use case data into a database after receiving use case creation request information;
10 After a user selects a to-be-executed use case and a to-be-tested device on a web front-end page and clicks a use case execution button, the web front-end page automatically sends a use case execution request to a web back-end use case management agent through a web server;
11 The use case management agent further forwards the request to a host machine adapter/a virtual machine adapter through an adapter message forwarding module according to equipment information contained in the use case execution request, the host machine/the virtual machine adapter calls a local use case execution module and further calls a hardware peripheral drive, and a use case is executed on the simulated hardware peripheral module;
12 After the host/virtual machine adapter finishes executing the use case, the use case execution state is forwarded to a use case management agent through an adapter message forwarding module, and the use case management agent stores the use case execution state into a database;
13 The Web front-end page sends a case state query request to the case management agent, the case management agent returns case state information to the Web front-end page after querying the case state request from the database, and the Web front-end page displays case execution states including success, failure, specific error codes and the like;
14 When the host/virtual machine cannot issue the heartbeat due to software and hardware abnormity (such as abnormal exit of the host/virtual machine adapter module and forced closing of the virtual machine), the equipment management agent module detects that the heartbeat of the host/virtual machine is overtime, changes the state of the host/virtual machine into the state of equipment offline and stores the equipment offline into the database, and returns the state of the equipment offline and displays the equipment offline state to the web front-end page when the web front-end page sends an equipment state query request;
in summary, the heartbeat request and the use case execution process of the host adapter and the virtual machine adapter are the same, and the only difference is that the host adapter has a device creation function and can create a virtual machine including a simulated hardware peripheral module and an execution software environment thereof.
Further, referring to fig. 3, fig. 3 shows a schematic flow diagram of creation/deletion of the device of the present invention, and the key execution flow in the way is as follows:
1) The equipment management agent module sends the parameters required by the backend host hypervisor to start the virtual machine, including the number of processors, the memory capacity, the hard disk capacity, the mirror image template identification, the analog hardware peripheral module identification and the like, to the adapter message forwarding module through the release message, and then the adapter message forwarding module forwards the messages to the host adapter;
2) The host machine adapter caches the received equipment creating request to a linked list, and the purpose is to avoid the blocking of an adapter message forwarding module due to the fact that messages in a message queue of the adapter message forwarding module are not taken away timely, so that the response speed of a web page is improved;
3) The host adapter informs the device management agent module to obtain the IP address through the message forwarding module, and the device management agent module obtains 1 IP address in an idle state from the IP address table of the database and modifies the state of the IP address into an in-use state;
4) Judging whether the virtual machine image of the appointed IP is created for the first time or not according to the fact that whether the host machine has the virtual machine image of which the file name comprises the suffix of the appointed IP address or not, if so, copying a new virtual machine image from a virtual machine image template, otherwise, multiplexing the previously copied virtual machine image, and avoiding the need of copying the image again every time;
5) Modifying an IP address configuration file in the virtual machine mirror image through a virtual machine mirror image operation software library such as libgustfs and the like;
6) Starting a heartbeat thread in the virtual machine adapter, continuously sending a device heartbeat message to the device management agent module through the adapter message forwarding module, updating the device state to be an online state after the device management agent module receives the heartbeat message, and storing the device state and the IP address information into a database;
7) Because the mirror image file name of the virtual machine has an IP address suffix, after the virtual machine is started, the name of the process of the virtual machine has an IP address identifier, the process can be inquired through the process filtering command of an operating system, such as commands of ps, grep and the like, and the process of the virtual machine can be killed and the virtual machine can be forcibly closed through the killing command of the operating system, such as a kill command and the like;
8) Restoring the IP of the virtual machine to be idle in the initial stage so as to obtain the IP again when equipment is created next time;
the hardware test environment may be customized by deploying different command processing modules for different virtual machine image templates.
The technical scheme of the invention provides a virtualized chip test system, which can bring the following beneficial effects:
the scheme reduces the use difficulty of the chip simulation test system. Technical personnel at any level can easily enter the system and use the tool to execute test verification work, the tester does not need to master professional knowledge such as various virtualization, operating systems, hardware principles, equipment drive development and test code development, and does not need multi-role matching to execute a chip test work, the test environment is simple to build, and only a computer provided with a browser is needed to be used as the test equipment.
The scheme reduces repeated environment building work of testers. The method comprises the steps of creating/deleting a flow and a general test case execution flow by automatic equipment, so that a tester can build a simulated hardware test environment for a specific chip only by adding hardware equipment for simulating chip behaviors in a hypervisor and deploying different test modules in different virtual machine mirror image templates, and repeated processes of virtual machine creation, operating system installation, network configuration and the like do not need to be executed.
The scheme reduces software and hardware abnormity caused by test environment conflict. The unified device management mechanism enables all users to execute the test only by using the test environment bound to the user, thereby avoiding the problem of test environment conflict caused by the fact that a plurality of users use the same test environment under the condition of mutual agnostic. The unified equipment creating process also avoids the problem of network address conflict or other environment deployment conflict caused when a plurality of users configure the network environment of the host machine and the virtual machine by themselves.
