Step shown in the flowchart of the accompanying drawings can be in a computer system such as a set of computer executable instructions
It executes.Also, although logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable
Sequence executes shown or described step.
Embodiment one
A kind of method for distributing IP address is present embodiments provided, as shown in Figure 1, this method includes S11-S13:
S11, after receiving the IP address request message of virtual machine, sending to all virtual machines includes IP address to be allocated
Broadcasting packet, judge whether IP address to be allocated has distributed；
S12, when judging result is to have distributed, retransmit the broadcasting packet comprising new IP address to be allocated and simultaneously sentence
Whether new IP address to be allocated of breaking has distributed, until judging result is unallocated；
It S13, is that unappropriated IP address distributes to virtual machine by judging result.
The DHCP method for avoiding distribution from occupying IP address is realized under virtualized environment, and DHCP distribution is avoided to occupy IP
Suspension failure caused by conflicting.
In a kind of exemplary embodiment, judge whether IP address to be allocated has distributed, comprising:
Whether have whether back message judges IP address to be allocated according to the broadcasting packet comprising IP address to be allocated
It has distributed.
When not receiving back message in preset time, judging result is unallocated；When receiving back message, sentence
Disconnected result is to have distributed.
In a kind of exemplary embodiment, all virtual machines are the void that a VLAN is belonged to the virtual machine of IP address requesting
Quasi- machine.Address requests message can be DHCP DISCOVER request message.
In a kind of exemplary embodiment, wherein broadcasting packet is free Address Resolution Protocol ARP broadcasting packet；It responds
Message is Address Resolution Protocol ARP back message.
In a kind of exemplary embodiment, IP address to be allocated is from the preset address comprising IP address to be allocated
It is obtained in pond.
In the embodiment of the present invention, after the IP address request message for receiving virtual machine, to all virtual machines send comprising to
The broadcasting packet of the IP address of distribution, judges whether the IP address to be allocated has distributed；When judging result is to have distributed,
It retransmits the broadcasting packet comprising new IP address to be allocated and judges whether the new IP address to be allocated has divided
Match, until judging result is unallocated；It is that unappropriated IP address distributes to the virtual machine by the judging result.Virtual
Change the DHCP method realized under environment and distribution is avoided to occupy IP address, DHCP distribution is avoided to occupy suspension caused by IP conflicts
Failure.
Embodiment two
Above-described embodiment method is specifically described in the present embodiment, as shown in Fig. 2, two virtual machines belong to it is identical
VLAN, wherein the IP configuration of virtual machine 1 is dynamic acquisition IP, and the IP configuration of virtual machine 2 is static IP, which is
192.168.1.20.Dynamic Host Configuration Protocol server is communicated by virtual switch OVS with the two virtual machines.The present embodiment is in virtualization ring
Under border, Dynamic Host Configuration Protocol server detects whether there is the IP address to be distributed by sending gratuitous ARP, if there is no the IP to be distributed
The IP is just distributed to virtual machine and used by address, Dynamic Host Configuration Protocol server.Implementation process the following steps are included:
(1) Dynamic Host Configuration Protocol server receives the DHCP DISCOVER request message of the sending of virtual machine 1.
(2) before distributing IP to virtual machine 1, Dynamic Host Configuration Protocol server detects the IP address to be distributed, and Dynamic Host Configuration Protocol server is sent
One Target IP is the gratuitous ARP broadcasting packet of 192.168.1.20, which can be transferred to virtual machine 1 by virtual switch
With virtual machine 2, Dynamic Host Configuration Protocol server waits 3 seconds to receive ARP back message.
(3) it since virtual machine 1 does not have IP address, is given a response so will not broadcast this gratuitous ARP.Due to virtual machine
2 IP is 192.168.1.20, and the Target IP of this gratuitous ARP broadcasting packet is 192.168.1.20, so virtual machine 2 returns
This gratuitous ARP is answered to broadcast.
(4) Dynamic Host Configuration Protocol server receives the ARP back message of virtual machine 2, illustrates that this IP192.168.1.20 is empty
Quasi- machine occupies, and Dynamic Host Configuration Protocol server marks the IP that wouldn't can be used, and Dynamic Host Configuration Protocol server selects next to be distributed in dhcp address pool
IP address, such as 192.168.1.100 sends the gratuitous ARP broadcasting packet that Target IP is 192.168.1.100 again.
(5) Dynamic Host Configuration Protocol server waits 3 seconds, due to virtual machine 1 and virtual machine 2 all without occupy 192.168.1.100 this
IP, so not having ARP response, this IP 192.168.1.100 is just distributed to virtual machine by Dynamic Host Configuration Protocol server after 3 seconds time-out
1。
The function of increasing detection IP in Dynamic Host Configuration Protocol server detects whether there is the IP to be distributed by sending gratuitous ARP
Address, if there is no the IP address to be distributed, which is just distributed to virtual machine and used by Dynamic Host Configuration Protocol server.
