Number N, wherein, M and N is the natural number more than 0.
Wherein, IP resource pools are one group of IP set, carry out the size of regulation IP resource pools with IP scopes and start over position,
IP resource pools are located in the database of cloud platform control node.The status information of IP includes idle and busy two in IP resource pools
The state of kind.
S302, whether the M is judged more than or equal to the N, if it is, S303 is performed, if it is not, then performing
S304。
If S303, the M are more than or equal to the N, N number of IP is selected as default IP from the idle IP.
If S304, the M are less than the N, new IP resource pools are created, as the 2nd IP resource pools, by described second
IP resource pools are connected to form the 3rd IP resource pools with the first resource pond by router, from the 3rd IP resource pools
Selection status information is idle N number of IP as default IP.
Wherein, the 2nd IP resource pools belong to different IP sections from an IP resource pools, are connected by router, can just make the
Virtual machine communication in one IP resource pools and the 2nd IP resource pools.
Alternatively, in another embodiment of the application, after the default IP settings are completed, also include：
It is busy by the state information updating of the default IP.
After default IP settings are completed, can be closed in the generation binding of the MAC Address of default IP and the network interface card of virtual machine
It is busy by the state information updating of default IP after system.
Alternatively, the virtual machine in virtual machine and configuration file that IP is not write in configuration file including having been written into IP's
Virtual machine, wherein the IP having been written into the virtual machine of IP is different from the default IP.
Wherein, the virtual machine that IP is not write in configuration file refers to the virtual machine of new establishment, and the new virtual machine for creating does not set also
Put IP, have been written into that the virtual machine of IP refers in configuration file IP has been set but IP is not disposed in the network IP resources pond of cluster
Virtual machine, when needing to add the network IP resources pond in cluster, when virtual machine starts, it is necessary to update IP.
