Abstract

The invention provides a method and a device for allocating network resources of virtual machines. The method comprises that a first physical host receives virtual information resource request messages sent by a user, and the virtual machine resource request messages are used for requesting for allocating network resources of at least one virtual machine; the first physical host allocates private virtual local area network (VLAN) resources for the user in a private VLAN resource pool of the first physical host if the virtual machine resource request messages request for allocating network resources of one virtual machine, and the private VLAN resources are used for separating the virtual machine in two-layer networks; and if the virtual machine resource request messages request for allocating network resources of at least two virtual machines, the first physical host allocates community VLAN resources for the user in a community VLAN resource pool of the first physical host, and the community VLAN resources are used for being communicated with the virtual machine in the two-layer networks. A great many user demands are met through the method and the device.

Description

technical field [0001] The present invention relates to computer technology, and in particular, to a method and device for allocating network resources of a virtual machine. Background technique [0002] 802.1Q VLAN (Virtual Local Area Network) is a virtual local area network, which is a technology that realizes virtual work groups by dividing the devices in the local area network into network segments logically rather than physically. VLAN technology allows network managers to logically divide a physical LAN into different broadcast domains. Each VLAN contains a group of computer workstations with the same needs and the same attributes as a physically formed LAN. [0003] In the prior art, each tenant is assigned a VLAN. However, in this mode, due to the limitation of the 802.1Q VLAN protocol, it can only support up to 4094 VLANs. Therefore, it can only serve up to 4094 tenants, which cannot meet the needs of a large number of users. need. SUMMARY OF THE INVENTION [00...
