Example one
The embodiment of the application provides a PXE function test method for a network card; specifically, the testing of the PXE function of the network card by using the method disclosed in this embodiment includes:
s1, building a hardware test environment, and installing the network card to be tested to a test server.
Specifically, when a hardware environment is built, it is required to ensure that a test server supports a hardware virtualization function, and at present, the server generally supports the hardware virtualization function, where for virtualization of a CPU (Central Processing Unit), some machines support hardware themselves, but options in a BIOS (Basic Input Output System) need to be modified to ensure that hardware virtualization can be supported, that is, VT (vandeool, virtualization technology) of the CPU in the BIOS setting is enabled (feasible).
In addition, influenced by the type of the network card to be tested, the strategy is different when the hardware environment is built, and at present, two kinds of network cards are mainly distinguished according to the number of network ports: the single-port network card and the double-port network interface have the following establishing strategies respectively: when a single-port network card is selected as a network card to be tested, a test server is provided with two single-port network cards to be tested, the two single-port network cards to be tested are directly connected through a network cable, and the two network ports are marked as a first physical network port and a second physical network port; when the dual-port network card is selected as the network card to be tested, only one test server needs to be installed, two network ports on the dual-port network card to be tested are directly connected through a network cable, and similarly, the two network ports are respectively marked as a first physical network port (eth 0) and a second physical network port (eth 1). After the network card to be tested is installed in the test server, it is further necessary to ensure that the network card to be tested can be normally identified on the link, so that the embodiment of the present application further proposes that the firmware version of the network card to be tested is refreshed when the network card to be tested is installed in the test server, where the firmware version is the version to be tested, because the PXE function of the network card to be tested is not supported in a specific version or needs to be additionally set to open the PXE function of the network card to be tested.
S2, configuring a software environment of the test server to ensure that a virtual machine can be created in the test server.
Specifically, the software environment configuring the test server mainly refers to a software package required for installing a Linux OS (Operating System) and installing a KVM (Kernel-based virtual Machine). The KVM is a lightweight virtualization management program module, mainly from a Linux kernel, is an open-source system virtualization module, needs hardware support, and belongs to full virtualization. Installing necessary software in a Linux system through a system self-contained command yum (yellowdog update management) tool, wherein the specific commands are as follows: yum install kvm libvirtpython-virtinst qemu-kvm virt-viewer bridge-utils. After downloading is completed, relevant services are started, and the specific command is as follows: d/libvirtual start. The complete Centos8.2 system ISO file is copied to/root path, wherein the ISO file is a file system issued by the International Organization for Standardization (ISO) for optical disc media, and is usually referred to as an optical disc image file. Then, a virtual machine management interface of the KVM can be opened through a virt-manager command in the imaging interface, the test virtual machine is tried to be installed, specifically CentOS8.2.Iso under root can be selected/installed as a system mirror image, and other settings are defaults; if the created test virtual machine is started normally, continuing the subsequent operation, otherwise, checking whether the system configuration file and the software package have problems according to the error information which can be reported, adjusting the system configuration file and checking the software environment until the test virtual machine can be normally installed and started; at this time, the test virtual machine is only used to determine whether the software environment in the test server supports KVM, i.e. it is ensured that the operating system in the test server can start the virtual machine and does not participate in the subsequent PXE function test.
S3, creating a first Virtual Machine (VMA), and configuring a PXE service end environment in the first VMA to enable the first VMA to provide a PXE service function.
After the KVM environment is prepared normally, a first virtual machine is created, and the first virtual machine is installed with default CPU and memory configuration through an ISO file required by a specified operating system. Before a first virtual machine is started, hardware configuration needs to be modified, a Network Interface Controller (NIC) option is configured to be an eth0: macvtap mode, and the method specifically operates to select a custom configuration before starting the virtual machine, and select Finish to enter a configuration interface before starting the virtual machine. And selecting a configuration option menu of the NIC, selecting an eth0 option through the following menu, namely a macvtap option, and starting the first virtual machine after setting the application. After the first virtual machine is started, the virtualized port in the first virtual machine can be seen, which is marked as a first virtual port (veth 0), and the virtualized port is actually a device virtualized by a first physical port (veth 0), that is, the virtualized port is connected with the network card to be tested through the first physical port.
After a first virtual machine is started, a PXE service end environment is configured in the first virtual machine so that the first virtual machine can provide a PXE service function, and the specific configuration method mainly comprises the following steps: 1. closing the firewall; 2. modifying a DHCP (Dynamic Host Configuration Protocol) service Configuration file, starting a Dynamic Host Configuration service, and taking a first virtual network interface as a Dynamic Host Configuration service network interface; 3. configuring a TFTP (simple File transfer protocol) service configuration File and starting a simple File transfer service, wherein a first virtual network port is used as a simple File transfer service network port; 4. configuring an HTTP (Hypertext Transfer Protocol) service configuration file and starting a HyperText Transfer service; 5. importing PXE service files including a boot file, a kernel file, a boot menu file, a boot image file and the like; for example, in the embodiment of the present application, bootx64.Efi of CentOS8.2 may be extracted as a boot file, grub.cfg as a menu file, vmlinux and initrd.img as a kernel file, and CentOS8.2.Iso as a boot image.
And S4, creating a second virtual machine (VM B), and configuring the starting mode of the second virtual machine to be starting from the network card to be tested.
And creating a second virtual machine, and selecting network boot (namely PXE boot) without specifying an ISO file for booting, wherein a virtual CPU, a memory and a hard disk of the second virtual machine can be configured according to default. Before starting the second virtual machine, the hardware configuration needs to be modified, a custom configuration before instance option is selected, a network card option is selected, then the virtual devices in the device list are deleted, then additional devices are selected, namely PCIE devices are added, and the number of the added PCIE devices is the number of the second physical network port before the first virtual machine is started (namely, the added PCIE devices are the network cards to be tested); storing the settings, namely, adding a PCIE device (network card to be tested) in the virtual machine device list, opening the Boot Options to see a PCIE device option added to the Boot device, checking the PCIE device option, and checking out the virtual device Boot option therein, so as to ensure that the second virtual machine can only be booted through the PCIE device (that is, configuring a Boot mode of the second virtual machine to be booted from the network card to be tested); in addition, the BIOS type of the virtual machine B needs to be modified to be UEFI (Unified Extensible Firmware Interface) mode, the Unified Extensible mode corresponds to bootx64.Efi in the PXE server constructed by the first virtual machine, and the booting can be normally completed only in this mode. The topology shown in fig. 1 is formed after the configuration is completed.
And S5, starting the second virtual machine, and if a PXE function boot interface is displayed, judging that the PXE function of the network card to be tested is normal.
Specifically, after the configuration of the second virtual machine is completed, the second virtual machine is started, and if a PXE function boot interface can be displayed, and then a 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 validity of the PXE function test, the embodiment of the present application further provides that a network card firmware (firmware) management tool is installed in the test server operating system, the value of the firmware register is modified by the network card firmware management tool, so that the PXE function of the unified extensible mode of the network card to be tested is turned off, then the second virtual machine is restarted, if 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 the PXE function of the network card switch to be tested is further verified to be valid.
In addition, in order to facilitate testing of the stability of the network card PXE function, the embodiment of the present application further provides that a KS (kick start)) automatic response file may be created to implement automatic installation of the PXE boot system, and the second virtual machine is automatically restarted after the system is successfully installed to implement circular testing of the network card PXE function, so as to verify the stability of the network card PXE function. The PXE boot system can be written into the virtual disk, so that frequent re-partition and formatting operation of the physical disk is effectively avoided, the loss of the service life of the physical disk is reduced, and meanwhile, the virtual device can be quickly initialized, so that the time for multiple cycles can be effectively reduced. The Kickstart is one of unattended installation modes, and the operating principle of the Kickstart is that various parameters filled by manual intervention are recorded in the installation process, and a file named ks.cfg is generated; if the parameter needs to be filled in the automatic installation process, the installation program firstly searches the ks.cfg file, and if the proper parameter is found, the found parameter is adopted; if not, popping up a dialog box to allow the installation to start manual writing; therefore, the KS auto-answer file covers all parameters needing to be filled in the installation process, and the KS auto-answer file can be used for realizing the automatic installation of the PXE boot system.
