The technical abbreviations referred to in this specification are as follows:
OVC (OS-levelVirtualContext): an operating system level virtual environment is a novel device virtualization technology for virtualizing a physical device into a plurality of logical devices. When the logic devices are divided, each logic device has independent hardware and software resources, routing and forwarding table items are maintained independently, the logic devices are managed independently through independent administrators, log management mechanisms and the like, and the operation of the logic devices on the same physical device is not affected mutually. In hardware, each virtual device has independent resources such as a main control board, a service board card, a port, a CPU (central processing unit), a memory and the like; in software, each virtual device has an independent control, forwarding, service and management plane, and runs processes independently without mutual interference.
VRF (virtual rout ingress forwarding, virtual routing and forwarding) technology is a novel virtualization technology for virtualizing a physical device into multiple logical devices. When dividing the logic devices, each logic device only has an independent routing table and a set of interfaces. VRF is mainly the isolation of the forwarding layer, and the system resource is shared and preemptive. Since logical devices isolated by the VRF cannot directly communicate with each other, the VRF allows IP addresses to overlap between virtual networks.
Virtual system: the virtual system is that a same environment is virtualized on the existing operating system, and an application program is run in the virtual environment, and all activities of accessing and changing the system are limited in the environment, so that the operation of the virtual system does not affect the physical system. The virtual system divides different resources according to different types, and the current common virtual systems include the following: OVC-based virtual systems, VRF-based virtual systems, interface-based virtual systems.
Conversation: a session refers to the process by which an end user communicates with an interactive system. For example, entering the operating system by entering an account password to exiting the operating system is a session process.
And (4) process: the program in the computer is a basic unit for resource allocation and scheduling of a system with respect to one-time operation activity on a certain data set, and is the basis of an operating system structure.
Command: the command is a row of character string expression formed by combining the keywords and the parameters in a certain sequence. Keywords refer to words that are fixed and invariant, and are used to indicate the specific meaning of subsequent parameters. Parameters refer to variable configuration parameters. For example: noipaddress192.168.0.1/16, wherein no, ip and address are keywords, and 192.168.0.1/16 is a parameter.
Command line: a service program running on a device provides functions of parsing commands, executing commands, and the like.
And (3) system calling: when a user process initiates a system call, the CPU switches to the kernel mode and starts to execute a kernel function. The kernel function is responsible for responding to the requirements of the application program, such as operating a file, performing network communication or applying for memory resources.
Aiming at the technical dilemma in the prior art, the method provides an implementation scheme for restarting the virtual system by using software, and the virtual system can be restarted in two modes, wherein one mode is to restart the virtual system by a command line, and the other mode is to restart the virtual system by a page. The manner of restart is different, but the flow is the same. The virtual system restarting method and the virtual system restarting device can restart the designated virtual system under the condition of not influencing the use of other virtual system users, reduce the loss of the user due to network interruption, and have good application experience for the user because the virtual system is restarted in a short time because the physical device is not restarted. The present disclosure is described in detail below with reference to specific examples.

More specifically, all interfaces under the virtual system are down, the session is deleted, and at this time, the network is not connected, so that the user needs to be removed from the virtual system in order to provide a better restart experience for the user, and the administrator is forced to exit from the login state, so that the state of closing the virtual system is realized.
In S210, the target virtual system is initialized. The method comprises the following steps: initializing a time of the target virtual system; taking the time as the starting time after restarting; session resources are initialized. But also can apply for certain resources for establishing the session, etc.

As shown in fig. 3, in S302, a close command is sent to the service group under the target virtual system.
In S304, the service group determines an action to be performed according to the close event handling mechanism.
In S306, the service group executes the action to close the interface corresponding to the service group. After the closing instruction is executed, the serial port of the target virtual device cannot receive the message.
Different types of virtual systems contain different resources, such as a virtual system based on VRF, a virtual system based on OVC, and a virtual system based on an interface, but the interaction of messages between the virtual systems is realized through interfaces under the resources, so that the virtual systems directly or indirectly possess the interface resources. In order to prevent the message between the interfaces from being forwarded, all the interfaces under the virtual system need to be down. The interface has a down event processing mechanism, down sends down events to each service group, each service group receives the message and then performs corresponding processing, for example, the routing module deletes the route after receiving the event message, at this time, the message cannot be forwarded.
