An electronic device in a vehicle includes at least one interface to a vehicle bus, at least one processor, and at least one memory including program code. The program code causes the electronic device to configure the interface to communicate with a controller in the vehicle over a transport protocol. The program code causes the electronic device to be accessible to the controller over the interface as a block device. The program code causes the electronic device to, upon receiving, from the controller, a request to access the block device over the transport protocol, read data from the block device and transmit, to the controller, the data over the transport protocol.

This invention discloses a method, apparatus, medium, and device for deploying virtual machines based on network block devices, belonging to the field of virtual machine deployment. After obtaining the virtual machine image to be deployed and the target deployment node, this application maps the virtual machine image to a network block device and performs a read-only mount on the target deployment node. A snapshot is created based on the read-only mounted network block device, and the virtual machine is started accordingly. This allows the virtual machine to run immediately even before the image data is fully localized. Subsequently, during the virtual machine's operation, the data of the read-only mounted network block device is copied to the target deployment node, completing the virtual machine deployment. This application effectively solves the problem that existing technologies cannot accurately and efficiently deploy virtual machines.

A system for leveraging local / user-side resources (i.e., memory) to store Non-Fungible Tokens (NFTs) and conduct NFT-related computational processes required for generating / minting or exchanging an NFT. The local / user device is equipped with super Non-Volatile Random Access Memory (NVRAM), which operates in accordance with a resource-sharing protocol, such as Network Block Device (NBD) protocol or the like. The resource-sharing protocol is registered with the user's NFT digital wallet, which is in communication with the distributed trust computing networks and, thus links the local / user-side resources (i.e., NVRAM) with the distributed trust computing network for resource sharing capabilities.

The subject disclosure pertains to communication between electronic devices (ECUs, ECMs, central control units) in a vehicle. For example, the subject disclosure provides an electronic device in the vehicle, comprising at least one processor and at least one memory including program code. The program code causes the electronic device, when executed with the at least one processor, to: configure the interface to communicate with a controller in the vehicle over a transport protocol; configure the electronic device to be accessible to the controller over the interface as a block device; upon receiving, from the controller, a request to access the block device over the transport protocol: read data from the block device; and transmit, to the controller, the data over the transport protocol.

The application discloses a method and system for transmitting local file data to a virtual machine block device, and belongs to the technical field of computer virtual devices. The application uses websocket transmission technology and NBD (Network Block Device) technology, and through designing a management and forwarding device, i.e. a block device mounting management device, mounting requests of clients are uniformly managed, and the block device mounting management device can serve as an intermediary to establish a connection between the clients and a virtualization hypervisor layer, so that mutual communication is achieved. Then, the NBD protocol is used to mount the block device as a network device. The application can directly mount read-only block device files (such as optical drive files, block disk files and the like) to a virtual machine through a web browser, and realizes corresponding systems. Therefore, the purpose of directly remotely mounting and unmounting and transmitting data on demand without uploading block device files and without additionally downloading a client auxiliary can be achieved.

The application provides a method for improving the read-write performance of a virtual machine image file, and belongs to the technical field of virtual machines, and comprises the following steps: S1: kernel module loading and initialization, loading a loadable kernel module QCOW2 driver for realizing QCOW2 analysis function; S2: QCOW2 image file metadata analysis, opening a specified QCOW2 image file, and analyzing the header structure and metadata of the QCOW2 image file; S3: device mapping framework device creation, creating a new virtual block device through a device mapping framework interface and associating the new virtual block device with the QCOW2 image file analyzed in step S2; and S4: input / output request processing. The method of the application avoids the context switching between the user state and the kernel state and the network block device protocol overhead.

A network block device protocol. The invention relates to communication between electronic devices (ECUs, ECMs, central control units) in a vehicle. For example, an electronic device in a vehicle includes at least one processor and at least one memory containing program code. The program code, when executed with the at least one processor, causes the electronic device to: configure the interface to communicate with a controller in the vehicle over a transport protocol; configuring the electronic equipment as block equipment which can be accessed by the controller through the interface; upon receiving a request to access the block device from the controller through the transport protocol: reading data from the block device; and sending the data to the controller through the transport protocol.
