Description
Technical field
The present invention relates to field of cloud computer technology, the virtual machine of particularly a kind of utilization serial ports and DHCP protocol communication is static
Network setting method.
Background technology
Set in the static network of field of cloud calculation virtual machine, current major part is using the skill of virtual machine serial communication
Art, virtual machine internal is passed to by the network information of virtual machine, and virtual machine internal receives network information static state setting network again.This
The method of kind needs incoming more network packet to virtual machine internal, and virtual machine internal constantly reads its network packet, believes
Breath amount is big and communication is than in the case of more frequently, it may appear that clogged with messages and the situation of messaging failure, so as to influence virtual
The static network of machine network is set.And DHCP protocol obtains dynamic network information as ripe technology, its protocol communication
Stability it is reliable, but if virtual machine completely by the way of DHCP dynamic access, it is necessary to some cycles are continued
Phase operates, and just can guarantee that the normal of network；If renewing failure, the information of network can be influenceed to lose, cause the interruption of network.
The content of the invention
Present invention solves the technical problem that being that the virtual machine static network that a kind of utilization serial ports and DHCP protocol communicate sets
Method is put, solving tradition carries out the instability problem of static IP setting using the serial ports transmission network information.
The present invention solve above-mentioned technical problem technical scheme be,
Described method comprises the following steps：
Step 1：The network configuration information of virtual machine is set on the dhcp server；
Step 2：Virtual machine carry network interface card is given in virtual machine host machine；
Step 3：Host sends network configuration event by serial communication to virtual machine；
Step 4：Virtual machine internal network configuration agency obtains network configuration event；
Step 5：Network configuration agency's adjustment network configuration is the automatic acquisition modes of DHCP, and DHCP is obtained using DHCP protocol
Network configuration information on server；
Step 6：Network configuration information is persisted in network profile, most at last the network of virtual machine from DHCP from
Dynamic acquisition modes become static network configuration.
Dynamic Host Configuration Protocol server network configuration information includes MAC Address, IP address, gateway address, the network segment, domain name resolution service
Device.
The virtual machine network interface card of described carry is consistent with MAC；Described virtual machine supports network interface card hot plug mechanism.
Dhcp client is broadcast on Dynamic Host Configuration Protocol server using DHCP protocol, obtains network configuration letter on Dynamic Host Configuration Protocol server
Breath.
Virtual machine internal network configuration agency concretely comprise the following steps：
(1) reliable and stable acquisition network configuration event；
(2) network configuration acts on behalf of running environment and supports cross-platform, including the operation of Windows, linux system；
(3) static network is set using DHCP protocol to set.
Static network sets and concretely comprises the following steps：
(1) dhcp client is utilized, DHCP request is sent to Dynamic Host Configuration Protocol server, obtain corresponding network configuration information；
(2) after obtaining network configuration information, network configuration information is persisted to by network configuration by network configurator
In file；
(3) network interface card is reloaded, static configuration is come into force.
Described network configuration event improves the packet of serial communication it is characterized in that the packet for sending is as far as possible short and small
Reliability, for example send message data " 1 " to virtual machine internal.
The method of the present invention is effectively solved complete using the stability of control ability and the DHCP protocol communication of serial communication
The instability problem of virtual machine network is set using serial communication, and realization principle is simple, reliable, is easily integrated into cloud computing
In platform.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is flow chart of the invention.
Specific embodiment
As shown in figure 1, implementation steps of the present invention are as follows：
(1) network configuration information of virtual machine, by taking dnsmasq servers as an example, wherein DHCP are set to DHCP Server
The configuration file of Server is as follows：
Virtual machine network interface card relevant configuration：Contain MAC Address, Hostname, ip addresses
fa：16：3e：b0：ff：0c, host-101-101-101-4.gcloudlocal, 101.101.101.5
Other specification is configured：Route, domain name service etc.
tag：Tag0, option：Router, 101.101.101.1
tag：Tag0, option：Dns-server, 101.101.101.4,101.101.101.3
(2) virtual machine carry network interface card is given in virtual machine host machine.
Implement using virsh order carries, wherein libvirt network profiles, it is as follows：
Wherein mac address are consistent with mac address in virtual machine network card configuration in DHCP Server, it is ensured that
Virtual machine internal obtains the correctness of virtual machine network configuration using DHCP protocol below.
(3) host sends network configuration event by serial communication to virtual machine
At present realize virtual machine one throw the net card network control, its serial data bag for being sent to virtual machine, with " 1 " data
Bag control, " 1 " represents and obtains virtual machine network configuration using DHCP protocol.Matching somebody with somebody for multiple virtual machine network interface cards is controlled if desired
Put, then using network interface card Mac addresses mark.
(4) virtual machine internal network configuration Agent obtains network configuration event, and the serial ports for implementing monitoring virtual machine leads to
Letter data, gets " 1 " packet, then it represents that to carry out network configuration.
(5) by taking Centos systems as an example, the network interface card for adjusting virtual machine is DHCP modes,
Network card configuration file ifcfg-eth0, it is as follows：
BOOTPROTO=dhcp
DEVICE=eth0
ONBOOT=yes
Then dhcp client programs are performed and obtains network configuration from dhcp server, such as issued orders：
Dhcpclient eth0 obtain the network configuration information of the network interface card of virtual machine, as follows：
interface“eth0”
fixed-address 101.101.101.5
routers 101.101.101.1
..............
(6) network configuration information by more than, is written in network card configuration file ifcfg-eth0, as follows：TYPE
=Ethernet
BOOTPROTO=static
DEVICE=eth0
ONBOOT=yes
IPADDR=101.101.101.5
GATEWAY=101.101.101.1
NETMASK=255.255.255.0
DNS1=101.101.101.4
DNS2=101.101.101.3.
