Abstract: The present invention discloses a method and a device for authorizing and using a virtual device, wherein the method comprises: after receiving a request for generating a virtual device, a mobile terminal configures authority information of a first virtual device, generates the first virtual device, and interacts with a servers to send the configured authority information of the first virtual device and related authentication information to the server for authenticating. After passing the authentication, the server generates a second virtual device with the above-mentioned authority information. When in use, the mobile terminal generates authentication information and sends a current use status of the first virtual device to the server for authenticating and is returned to with a authentication result. The present invention improves the security by adding the authentication with respect to the authority information during the authorization of generating the virtual device and use of the virtual device.

Abstract: A scheduling method for virtual processors based on the affinity of NUMA high-performance network buffer resources, including: in a NUMA architecture, when a network interface card (NIC) of a virtual machine is started, getting distribution of the buffer of the NIC on each NUMA node; getting affinities of each NUMA node for the buffer of the network interface card on the basis of an affinity relationship between each NUMA node; determining a target NUMA node in combination with the distribution of the buffer of the NIC on each NUMA node and NUMA node affinities for the buffer of the NIC; scheduling the virtual processor to the CPU on the target NUMA node. The problem of affinity between the VCPU of the virtual machine and the buffer of the NIC not being optimal in the NUMA architecture is solved to reduce the speed of VCPU processing network packets.
