In the prior art, configuration 1: the server UEFI BIOS configures a corresponding Host CPU; configuration 2: UEFI BIOS in the DPU configures the corresponding DPU; configuration 3: client (customer server) UEFI BIOS configuration inside the virtual machine. The configuration is relatively decentralized and not centralized, each part needs to be configured when facing to the construction of a large-scale data center, and when an administrator checks, the BMC (Baseboard Management Controller ) of each server needs to be logged in to remotely check the machine configuration condition, so that the configuration is relatively complicated and the centralized management is inconvenient; the data center administrator cannot fully obtain the configuration of each server, as well as the client BIOS for different domains on a node.
Specifically, the DPU (a special processor configured with data as a center, supporting infrastructure layer resource virtualization by adopting a software-defined technology route, supporting infrastructure layer services such as storage, security, quality of service management and the like) is responsible for creating and sharing virtualization related configurations through a network, the physical server and the UEFI (Unified Extensible Firmware Interface, which are specifications of a personal computer system under the VMM (virtual machine manager, for example qemu, xen and the like) are used for defining a software interface between an operating system and system firmware, and serve as an alternative scheme of the BIOS), the BIOS (Basic Input Output System, providing the bottommost and most direct hardware setting and control for a computer) uses the virto provide a virtual solution, which is a set of general I/O device virtualized programs, and is an abstraction of a set of general I/O devices in the semi-virtualized Hypervisor (virtual machine monitor), the IOMMU (Input/output memory management unit, which is a memory management unit (Memory Management Unit) which is used for connecting the DMA I/O Bus (Direct Memory Access-Bus) and not needed to access the relevant hardware configuration directly, and the like, and the important characteristics of the DPU need not to be accessed by the host device.
Fig. 1 is a schematic flow chart of a DPU-based virtualization configuration management method according to an embodiment of the present disclosure, where the method may be performed by a DPU-based virtualization configuration management apparatus, where the apparatus may be implemented in software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method includes:
step 101, acquiring corresponding virtualization configuration parameters from the DPU device according to a preset protocol at a target stage in the UEFI starting process of the main server, the virtual machine and each guest server.
Step 102, the host server, the virtual machine and each guest server perform virtualization configuration on the host server, the virtual machine and each guest server according to the corresponding virtualization configuration parameters.
In some embodiments, the virtualized configuration parameters sent by the data analysis center are received and stored at the DPU device of each host server.
In some embodiments, after the host server, the virtual machine, and each guest server are configured in a virtualized manner, configuration option values of UEFI of the host server, the virtual machine, and each guest server are determined, and the DPU device of the host server sends the configuration option values to the management center in the form of network packets.
In some embodiments, the DPU device of the primary server sends the configuration option values to the management center in the form of network packets at preset time intervals. The time interval is selected and set according to the application scene.
The cloud computing center is provided with a plurality of physical servers, one physical server is provided with a DPU device, a virtual machine is loaded on the physical server (UEFI+OS, UEFI starting), the virtual machine is provided with a plurality of guest servers (UEFI+OS), and the DPU device is provided with (UEFI+OS).
Specifically, the startup procedure of the UEFI system includes: SEC (security authentication) - > PEI (EFI pre-initialization) - > DXE (drive execution environment) - > BDS (boot device select) - > Guest OS (system in virtual machine), hostOS (system in host server). The target phase may be any phase in the above process, and may be selected as required, for example, DXE is used as the target phase.
Specifically, the DPU is a center of data processing, and the DPU plays a role in management throughout the data center. The UEFI BIOS corresponding to the host server, virtual machine, and each guest server boots, based on Intel Vt-d (VT-d isVirtualization Technology for Directed I/O (VT-d), virtualization technology of I/O. In short, PCIe ((Peripheral Component Interconnect Express), generally translated into a peripheral device high-speed connection standard, PCIe protocol is an end-to-end interconnection protocol, and provides a solution for high-speed transmission bandwidth), resources of devices are directly allocated to a virtual machine) technology, a preset protocol such as virtuo protocol is used to read parameters related to Virtualization in a DPU NVRAM (Non-Volatile Random Access Memory is a Non-volatile random access memory, which refers to a RAM capable of still maintaining data after power is off), NUMA (Non Uniform Memory Access, non-uniform memory access) is configured, vt-d, vt-x (Vt-x is an instruction set in intel application Virtualization technology, and is a hardware Virtualization technology of a CPU, vt can simultaneously improve Virtualization efficiency and security of a virtual machine, vt technology on an x86 platform is generally referred to as Vt-x, vt technology on an Itanium platform is referred to as Vt-i) and so on related to Virtualization parameters related to Virtualization, thereby implementing CPU, memory, IO, virtualization, etc. of nodes and domains.
Specifically, the data analysis center may communicate with a plurality of main servers, each having a corresponding DPU device, and the data analysis center writes the virtualization-related parameters corresponding to each server into the corresponding DPU device.
As shown in fig. 2, when the main server is powered on, the main server UEFI BIOS starts to operate, scanning the DPU device. The SOC (System on Chip) above the DPU device begins running the UEFI BIOS. After the main server enters the startup, the virtual machine under the monitoring of the VMM starts to run the UEFI BIOS, wherein the UEFI comprises SEC- > PEI- > DXE- > BDS- > Guest OS, and when the UEFI BIOS enters the DXE stage, the VirtIO protocol is called to read BIOS configuration about service requirements in NVRAM medium of the DPU device.
It will be appreciated that a default configuration option value, or a preference value to facilitate business needs, is required when the three UEFI BIOS is running. The disclosed embodiments consider that the preference values of these three parts are controlled by the DPU device, and should be present inside the DPU device. When many DPUs (and also many host servers) work together, the settings of these host servers may be aggregated together in the form of a network packet for viewing by a remote administrator.
That is, a large cloud computing center has tens of thousands of physical servers (main servers), where each physical server has a DPU card (DPU device) that sends its corresponding (physical server configuration option value setting, configuration option value setting in a virtual machine on the physical server, and configuration option value setting of the DPU device itself) to the management center in the form of a network packet.
In some embodiments, when the primary server UEFI starts to enter the target phase, the target protocol is invoked to read a first virtualization configuration parameter in the DPU device that matches the service requirement, and the target function is invoked to configure the first virtualization configuration parameter to the primary server.
In some embodiments, the BAR space in the DPU device is read by an input-output function to obtain the first virtualized configuration parameter.
In some embodiments, a virtual DPU device is created under a virtual machine manager VMM, a translation table is established and saved to a target space of the virtual DPU device, when a customer server accesses the target space of the virtual DPU device, the VMM forwards an input/output request to an input/output address space of the DPU device through the translation table, reads a second virtualization configuration parameter matched with a service requirement based on the input/output address space, and configures the second virtualization configuration parameter to the customer server.
Specifically, the current UEFI BIOS is based on the UEFI functional core framework written by intel, and among the modules, protocols are extremely important, and represent a class of services provided by the device, mainly including a protocol global unique identifier (GUID, globally Unique Identifier), a protocol interface structure (protocol interface struct) and a protocol service (protocol service). Through the function pointer and the data pointer, a user can design own codes and call the function call by an upper layer.
Specifically, when the main server and the UEFI BIOS under the VMM are running, first, a virtualization-related default preference value is obtained from the DPU device, specifically in the form of UEFI variable. The original run Services in the UEFI system are used for overwriting, and the functions are converted from the original cmos to the reading and writing of NVRAM of the DPU device. When the UEFI enters the DXE phase, the VirtIO protocol is called to read BIOS configuration about service requirements in NVRAM medium of the DPU device.
Specifically, the upper UEFI BIOS rewrites the system Get Variable and Set Variable functions:
SystemTable- > rutimeservices- > SetVariable = DPUVariableServiceSetVariable; the UEFI system function invokes a method of reading and writing DPU NVRAM.
SystemTable->RuntimeServices->GetVariable＝DPUVariableServiceGetVariable。
The virtual protocol is used for reading and writing NVRAM of the DPU device in DPUVARIABLE eServiceSetVariable and DPUVARIABLE functions, and the specific functions are shown as follows mainly through reading and writing BAR space of the DPU device:
IO function of read-write DPU device BAR:
the relevant virtualized configuration, such as NUMA, VT-d, VT-x, SR-IOV, etc., is first obtained from the DPU by definition of the BAR space, by the read-write functions of the UEFI system variables.
Setting and reading in NVRAM of the local server DUP device. This completes the configuration of the main server.
Specifically, unlike the physical server BIOS, the BIOS under the VMM saves virtualization-related settings inside the DPU via the VirtIO protocol, as shown in FIG. 3.
Adding virtual DPU equipment in qemu, and realizing the following partial code:
/>
specifically, the UEFI BIOS in the guest server accesses the IO address space of the physical DPU device, creates a virtual DPU device under the VMM, creates a conversion table (based on Intel EPT big page technology, the conversion table includes a mapping relationship between the virtual DPU device and the IO address space of the DPU), reports the virtual DPU BAR space to the guest server, and when the guest server accesses the BAR space of the virtual DPU device, the VMM is responsible for intercepting the operation and forwards the IO request to the IO address space of the DPU device through the conversion table (written by PCIE, both the write request and the read request are in PCIE specifications).
In addition, the BIOS settings stored in the DPU device settings are read by the DPU device and parsed by the DPU device SOC. The SOC may perform relevant settings for BIOS configuration according to service requirements and store in the DPU device NVRAM. The SOC on the DPU device reads and parses NVRAM content in the DPU device, and sends the NVRAM content to the data center in a form of a network packet for viewing by an administrator.
