Description

Technical Field

[0002] Preboot eXecution Environment (PXE) provides a way to start a computer through a network interface. The protocol is divided into client and server ends. With the continuous development and improvement of the PXE protocol, it is increasingly supported by many brands of network cards. As a result, the PXE function of smart network cards is also widely used in the server field. Network cards with PXE functions can support batch filling systems and diskless boot startup in server clusters. For servers, the deployment of large-scale test environments and production environments is of great significance. Therefore, the support of smart network cards for PXE functions is a key item to consider when selecting network cards and introducing components into servers.

[0003] There are existing testing methods for the PXE function of the network card, such as the patent CN113746694A, which proposes to deploy a network of a test machine and a machine to be tested, and the test machine cooperates with the designated machine to be tested to perform a PXE boot test in a loop. During the boot mode, the system is installed through the KS automatic response file, thereby verifying the network configuration of the network card and the stability of the PXE function. It is necessary to specially deploy a server that can provide PXE service functions (referred to as the PXE server), and the PXE server needs to open the DHCP (Dynamic Host Configuration Protocol) service and the TFTP (Trivial File Transfer Protocol) service, and it is also necessary to further deploy the files and environment required for PXE booting, and its configuration process is relatively complicated; at the same time, after the network card to be tested is installed on the test server, it needs to be connected to the local area network of the PXE server. For a test environment with multiple local area networks, its installation and deployment is relatively inconvenient.

[0068] Embodiment 1

[0069] The present application embodiment provides a method for testing the PXE function of a network card; specifically, using the method disclosed in this embodiment to test the PXE function of the network card includes:

[0070] S1. Build a hardware test environment and install the network card to be tested on the test server.

[0071] Specifically, when setting up the hardware environment, you must ensure that the test server supports hardware virtualization. Currently, servers generally support hardware virtualization. For CPU (Central Processing Unit) virtualization, some machines’ hardware supports it, but you need to modify the options in the BIOS (Basic Input Output System) to ensure that hardware virtualization is supported, that is, modify the CPU’s VT (Vanderpool, virtualization technology) in the BIOS settings to enabled.

[0072] In addition, affected by the type of network card to be tested, the strategies for building the hardware environment are different. Currently, there are two main types of network cards based on the number of network ports: single-port network card and dual-port network port. The construction strategies are as follows: When a single-port network card is selected as the network card to be tested, two single-port network cards to be tested are installed on the test server. The two single-port network cards to be tested are directly connected through a network cable, and the two network ports are recorded as the first physical network port and the second physical network port; when a dual-port network card is selected as the network card to be tested, only one network port needs to be installed on the test server. The two network ports on the dual-port network card to be tested are directly connected through a network cable. Similarly, the two network ports are recorded as the first physical network port (eth0) and the second physical network port (eth1). After the network card to be tested is installed on the test server, it is also necessary to ensure that the network card to be tested can be normally identified on the link. Therefore, the embodiment of the present application also proposes to refresh the firmware version of the network card to be tested to the version to be tested after the network card to be tested is installed on the server to be tested. The reason is that the PXE function of the network card to be tested is not supported under a specific version or additional settings are required to enable the PXE function of the network card to be tested.

[0073] S2. Configure the software environment of the test server to ensure that a virtual machine can be created in the test server.

[0074] Specifically, the software environment of the test server configured above mainly refers to the software packages required for installing Linux OS (Operating System) and installing KVM (Kernel-based Virtual Machine). KVM refers to a lightweight virtualization management program module, which mainly comes from the Linux kernel. It is an open source system virtualization module that requires hardware support and belongs to full virtualization. In the Linux system, the necessary software is installed through the system's own command yum (yellowdog update manage) tool. The specific commands are as follows: yum install kvmlibvirtpython-virtinst qemu-kvm virt-viewer bridge-utils. After the download is complete, start the relevant services. The specific command is: / etc / init.d / libvirtd start. Copy the complete CentOS8.2 system ISO file to the / root path, where the ISO file is a file system released by the International Organization for Standardization (ISO) for optical disc media, usually referring to an optical disc image file. After that, you can use the virt-manager command in the graphical interface to open the KVM virtual machine management interface and try to install a test virtual machine. Specifically, you can select CentOS8.2.iso under / root as the system image to install, and keep other settings as default. If the test virtual machine created at this time starts normally, continue with the subsequent operations. Otherwise, check whether there are problems in the system configuration files and software packages based on the error information that can be reported, adjust the system configuration files and check the software environment until the test virtual machine can be installed and started normally. The test virtual machine at this time is only used to determine whether the software environment in the test server supports KVM, that is, to ensure that the operating system in the test server can start the virtual machine, and does not participate in the subsequent PXE function test.

[0075] S3. Create a first virtual machine (VMA), and configure a PXE server environment in the first virtual machine to provide a PXE service function.

[0076] After the KVM environment is prepared normally, create the first virtual machine, specify the ISO file required by the operating system, and install it with the default CPU and memory configuration. Before starting the first virtual machine, you need to modify the hardware configuration and configure the network card (NIC, network interface controller) option to eth0:macvtap mode. The specific operation is to select Customize configuration before install before starting the virtual machine, and select Finish to enter the configuration interface before starting the virtual machine. Select the NIC configuration option menu, select the eth0:macvtap option through the following menu, and start the first virtual machine after applying the settings. After starting the first virtual machine, you can see the virtualized network port in the first virtual machine, recorded as the first virtual network port (veth0), which is actually the device virtualized by the first physical network port (veth0), that is, it is connected to the network card to be tested through the first physical network port.

[0077] After the first virtual machine is turned on, a PXE server environment is configured in the first virtual machine to enable the first virtual machine to provide a PXE service function. The specific configuration method mainly includes: 1. Turning off the firewall; 2. Modifying the DHCP (Dynamic Host Configuration Protocol) service configuration file, turning on the dynamic host configuration service, and using the first virtual network port as the dynamic host configuration service network port; 3. Configure the TFTP (Trivial File Transfer Protocol) service configuration file and turn on the simple file transfer service, using the first virtual network port as the simple file transfer service network port; 4. Configure the HTTP (HyperText Transfer Protocol) service configuration file and turn on the hypertext transfer service; 5. Importing PXE service files, including boot files, kernel files, boot menu files, boot image files and other files; wherein, the files required for the PXE function vary according to the operating system. For example, in the embodiment of the present application, CentOS can be extracted. 8.2's bootx64.efi is used as the boot file, grub.cfg is used as the menu file, vmlinuz and initrd.img are used as kernel files, and CentOS8.2.iso is used as the boot image. The embodiment of the present application does not specifically limit the selection of specific boot files, kernel files, boot menu files, etc.

[0078] S4. Create a second virtual machine (VM B), and configure the startup mode of the second virtual machine to start from the network card to be tested.

[0079] When creating a second virtual machine, there is no need to specify an ISO file for booting, but network booting (ie, booting through PXE) is selected, wherein the virtual CPU, memory and hard disk of the second virtual machine can be configured by default. Before starting the second virtual machine, you need to modify the hardware configuration, select Customize configurationbefore install, select the network card option, then delete the virtual device in this device list, and then select Add device, that is, add a PCIE device. The added PCIE device number is the second physical network port number (that is, the added PCIE device is the network card to be tested); save the settings, you can see that a PCIE device (network card to be tested) has been added to the virtual machine device list, and open the Boot Options option to see the newly added PCIE device option for the boot device. Check the PCIE device option and uncheck the virtual device boot option to ensure that the second virtual machine can only be booted and started through the PCIE device (that is, configure the startup method of the second virtual machine to start from the network card to be tested); in addition, you need to change the BIOS type of virtual machine B to UEFI (Unified Extensible Firmware Interface) mode. The above unified extensible mode corresponds to bootx64.efi in the PXE server built by the first virtual machine. Only in this mode can the boot be completed normally. After the configuration is completed, it will be formed Figure 1 Topology shown.

[0080] S5. Start the second virtual machine. If a PXE function boot interface is displayed, it is determined that the PXE function of the network card to be tested is normal.

[0081] Specifically, after the configuration of the second virtual machine is completed, the second virtual machine is started. If the PXE function boot interface can be displayed, and then the system installation interface is entered, it can be determined that the PXE function of the network card to be tested is normal. Further, in order to detect the effectiveness of the PXE function test, the embodiment of the present application also proposes to install a network card firmware management tool in the test server operating system, and modify the value of the firmware register through the network card firmware management tool so that the PXE function of the unified scalable mode of the network card to be tested is turned off, and then the second virtual machine is restarted. At this time, if it is displayed that the boot device cannot be found, it can be determined that the network card to be tested can normally turn off the PXE function, and further verify that the switch PXE function of the network card to be tested is effective.

[0082] In addition, in order to facilitate the testing of the stability of the PXE function of the network card, the embodiment of the present application also proposes that a KS (kickstart)) automatic response file can be created to realize the automatic installation of the PXE boot system, and automatically restart the second virtual machine after the system is successfully installed to realize the cyclic testing of the PXE function of the network card to verify the stability of the PXE function of the network card. Among them, the PXE boot system will be written into the virtual disk, which effectively avoids the frequent repartitioning and formatting operations of the physical disk, reduces the loss of the life of the physical disk, and at the same time, because the virtual device can be initialized quickly, it can effectively reduce the time used for multiple cycles. Among them, Kickstart is one of the unattended installation methods, and its working principle is to record various parameters filled in by manual intervention during the installation process and generate a file named ks.cfg; if there is a situation where parameters need to be filled in during the automatic installation process, the installation program will first search for the ks.cfg file, and if the appropriate parameters are found, the parameters found will be adopted; if not found, a dialog box will pop up to let the installer write manually; therefore, the KS automatic response file covers all the parameters that need to be filled in during the installation process, and can be used to realize the automatic installation of the PXE boot system.
