The invention provides a kind of virtual machine High Availabitity disaster recovery method, for high available virtual machine application system, referring to Fig. 1
It is shown, a kind of flow chart of the process of virtual machine High Availabitity disaster recovery method that Fig. 1 is provided for the present invention;The method includes:
Step s101:Create the high available virtual machine in primary server joint;
Step s102:Create the first Shadow Virtual machine on the first standby server node;
Certainly, can be carried out simultaneously between step s101 and step s102, the present invention does not limit its sequencing.
Step s103:Internal storage state and magnetic disc i/o number in high available virtual machine in real-time synchronization primary server joint
According to the first Shadow Virtual machine on the first standby server node;First Shadow Virtual machine is matched somebody with somebody on an equal basis with high available virtual machine
Put, and in an inactive state;
Step s104:The machine if primary server joint is delayed, activates the task of the first Shadow Virtual machine adapter high available virtual machine
Continue executing with.
It is understood that high availability Availability=MTBF (uptime)/[MTTR (out-of-service time)
+MTBF]。
Preferably, it is shown in Figure 2, another virtual machine High Availabitity disaster recovery method that Fig. 2 is provided for the present invention
The flow chart of process;Primary server joint is delayed and also include after machine:
Step s105:Trigger the second standby server node and create the second Shadow Virtual machine;
Step s106:Internal storage state and magnetic disc i/o data in real-time synchronization the first Shadow Virtual machine is empty to the second shadow
Plan machine;
Step s107:The machine if the first standby server node is delayed, second Shadow Virtual machine the first virtual machine of adapter of activation
Task is continued executing with.
It is understood that when high available virtual machine application system includes two or more server node, you can by the
Three server nodes are set to the second standby server node, standby second after the first Shadow Virtual machine adapter business
The second Shadow Virtual machine is created on server node, the high availability of virtual machine is further improved;Certainly, if high available virtual machine
When the server node that application system includes is more, the 3rd standby server node, the 4th active service can also be set
Device node etc., the server that the specific quantity for setting standby server node can be included according to high available virtual machine application system
Depending on the quantity of node and itself needs, the present invention is not especially limited to this, it is however noted that, on realizing
Function is stated, each server node is required to Simultaneous Monitoring function, i.e., can be same by the data in itself virtual machine in real time
In step to the Shadow Virtual machine of itself corresponding standby server node.
Preferably, high available virtual machine and the first Shadow Virtual machine and the first Shadow Virtual machine and the second shadow void
Communication frequency between plan machine is Millisecond.
It is understood that in order to ensure the data syn-chronization between each virtual machine Shadow Virtual machine corresponding with itself
Property, communication frequency needs between the two are sufficiently high, therefore communication frequency is preferably Millisecond, and certainly, the present invention does not limit logical
Believe the concrete numerical value of frequency, whether communication frequency is set using other ranks also dependent on actual conditions.
Preferably, high available virtual machine and the first Shadow Virtual machine and the first Shadow Virtual machine and the second shadow void
TCP (Transmission Control Protocol, biography transport control protocol are carried out by libvirtd C functions storehouse between plan machine
View) or RDMA (Remote Direct Memory Access, remote direct data access communication).
The invention provides a kind of virtual machine High Availabitity disaster recovery method, the high available virtual machine in primary server joint is just
Often during work, i.e., the first shadow on its internal storage state of real-time synchronization and magnetic disc i/o data to the first standby server node is empty
Plan machine, after master server delays machine, due to the data for having had high available virtual machine in the first Shadow Virtual machine, therefore
Data transfer is no longer needed, but the business of adapter high available virtual machine continues to hold immediately by only activating the first Shadow Virtual machine
OK.It can be seen that, the present invention can as far as possible ensure the continuity of business, it is to avoid because primary server joint is delayed caused by machine
Service disconnection and loss of data, improve the reliability and high availability of virtual machine business.
Present invention also offers a kind of virtual machine High Availabitity disaster tolerance system, for high available virtual machine application system, referring to
Shown in Fig. 2, a kind of structural representation of virtual machine High Availabitity disaster tolerance system that Fig. 2 is provided for the present invention.The system includes:

The first Shadow Virtual machine creation module 12 on the first standby server node is arranged at, for creating the first shadow
Virtual machine;
The Simultaneous Monitoring module 13 in primary server joint and the first standby server node is respectively arranged at, for real-time
Internal storage state and magnetic disc i/o data in synchronous high available virtual machine are to the first Shadow Virtual machine;First Shadow Virtual machine and height
Available virtual machine comparable configuration and in an inactive state;The machine if primary server joint is delayed, activation the first Shadow Virtual machine adapter
The task of high available virtual machine is continued executing with.
Preferably, the system also includes:
It is arranged at the Simultaneous Monitoring module 13 on the second standby server node;It is respectively arranged at the first standby server section
The internal memory shape that Simultaneous Monitoring module 13 on point and the second standby server node is used in real-time synchronization the first Shadow Virtual machine
State and magnetic disc i/o data are to the second Shadow Virtual machine;The machine if the first standby server node is delayed, the second Shadow Virtual machine of activation connects
The task of the virtual machine of pipe first is continued executing with;
Simultaneous Monitoring module 13 on first standby server node also includes:

Modeling block 14;
Module 14 is rebuild, for triggering the second Shadow Virtual machine creation module being arranged on the second standby server node
15;
Second Shadow Virtual machine creation module 15, for creating the second Shadow Virtual machine.
I.e. between high available virtual machine and the first Shadow Virtual machine and the first Shadow Virtual machine and the second Shadow Virtual machine
Between carry out data syn-chronization by two Simultaneous Monitoring modules 13, after primary server joint delays machine, in primary server joint
Simultaneous Monitoring module 13 first Shadow Virtual machine is activated by the Simultaneous Monitoring module 13 on the first standby server node, together
Reason, the first standby server node is delayed after machine, and the Simultaneous Monitoring module 13 on the first standby server node is standby by second
Simultaneous Monitoring module 13 on server node activates the second Shadow Virtual machine.
The invention provides a kind of virtual machine High Availabitity disaster tolerance system, the high available virtual machine in primary server joint is just
Often during work, i.e., the first shadow on its internal storage state of real-time synchronization and magnetic disc i/o data to the first standby server node is empty
Plan machine, after master server delays machine, due to the data for having had high available virtual machine in the first Shadow Virtual machine, therefore
Data transfer is no longer needed, but the business of adapter high available virtual machine continues to hold immediately by only activating the first Shadow Virtual machine
OK.It can be seen that, the present invention can as far as possible ensure the continuity of business, it is to avoid because primary server joint is delayed caused by machine
Service disconnection and loss of data, improve the reliability and high availability of virtual machine business.
