The invention discloses a virtual machine processor resource adjustment method, device and virtual machine system. The method includes: identifying whether there is a resource scheduling request on the VCPU for the VCPU to be deleted in the virtual machine VM; responding to the resource scheduling request on the VCPU, starting the response time threshold value of the automatic fault detection operation according to the operating system of the VM, and delaying the response Resource scheduling request, so that the resource scheduling request does not get a response within the response time threshold; in response to the resource scheduling request not getting a response within the response time threshold, the VM's operating system starts an automatic fault detection operation, and queues the VCPU The process is scheduled to other VCPUs of the VM; the VCPU is deleted to release the physical server CPU resources occupied by the VCPU. Through the technical solution provided by the invention, the VCPU resource can be reduced in the running state, and the elastic expansion and contraction of the virtual machine resource is realized.

The invention discloses a press reciprocating valve. The press reciprocating valve comprises a first pipeline, a sealing element, a handle and a fixed block, wherein a shell is arranged on the outer wall of the first pipeline; a central rod penetrating to the lower inner wall of the first pipeline is arranged in the shell; a valve clack is arranged on the central rod; the central rod further penetrates to the fixed block and the sealing element in the shell; and the top of the central rod is connected with the handle outside the shell. The press reciprocating valve further comprises a second pipeline, wherein an elastically-stretching self-locking structure used for enabling the second pipeline to elastically stretch relative to the first pipeline is arranged between the second pipeline and the first pipeline; the second pipeline is slidably connected to the first pipeline in a sleeving manner; and first water outlet holes are formed in the second pipeline. The valve is reasonable in design; moreover, the water outlet holes are formed in the pipelines, and are capable of dividing water into a plurality of different branches, thereby meeting the needs of people for the branches; and meanwhile, the valve has the advantage of being convenient to control.

The present invention relates to a firewall policy query, elastic scaling method, system, equipment, storage medium, and firewall policy query method, including: S1. Acquiring firewall policy configuration information, parsing the firewall configuration information into standardized format data, and constructing a firewall policy Information base; S2. According to the query information, automatically determine the source IP address in the firewall configuration information, the security zone to which the destination IP address belongs, and automatically judge the source IP address and the destination IP address flow path firewall device; S3 . Automatically calculating the policy correlation between the query information and the firewall policy; and feeding back the query result according to the policy correlation.

The present invention provides a method and system for uninterrupted service load balancing. The method includes: S1. The load balancing device judges in real time whether the service of the backend instance is available, and updates the service status of the backend instance to the data stored in the shared memory. Service availability list; S2, the shared memory writes the updated service availability list to the configuration file of each load balancing device in real time, and saves the configuration file persistently; S3, when the load balancing device receives a user request, select one according to the service availability list A backend instance can be used to handle user requests. Update the service status of the backend instance to the service availability list stored in the shared memory in real time; the shared memory uses an asynchronous method to write the change information of the service availability list into the configuration file, and notify other load balancing devices to update the relevant configuration files; Dynamically load requests to backend instances that do not exist in the configuration file when the load balancer is restarted.

The invention discloses a pressing reciprocating multi-connection hole valve, comprising a first pipeline, a second pipeline, a third pipeline, a sealing element, a handle and a fixing block, wherein a shell is arranged at the outer wall of the first pipeline; a center rod penetrating the inner wall under the first pipeline is arranged in the shell and is provided with a valve clack; the center rod also penetrates through the fixing block and the sealing element in the shell; the top of the center rod is connected with the handle outside the shell; an elastic telescopic self-locking structure for elastically extending and retracting the second pipeline relative to the first pipeline is arranged between the first pipeline and the second pipeline; the second pipeline slidably sleeves the first pipeline and is provided with first water outlets; the structure between the third pipeline and the second pipeline is identical with that between the second pipeline and the first pipeline.
