Specific embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail.
Fig. 1 be it is according to embodiments of the present invention to network disk carry out carry system 1 structure chart, the system 1 include pair Network carries out device 10, source physical machine 11, target physical machine 12 and the network disk 13 of carry.Fig. 2 is according to embodiments of the present invention The device 10 that carry is carried out to network disk structure chart, the device 10 include carry unit 101, setting unit 102, establish it is single Member 103, thermophoresis unit 104 and running unit 105.
Fig. 3 is the flow chart of the method according to embodiments of the present invention that carry is carried out to network disk.With reference to Fig. 1-3 pairs The embodiment of the present invention is described in detail.
In the present embodiment, network disk 13 is currently mounted in source physical machine 11 in a manner of the first carry, and supply source physical machine The source virtual machine 110 of upper operation uses.Here, the first carry mode is, for example, iSCSI (Internet Small Computer System Interface, internet small computer system interface), and according to the first corresponding disk of carry mode Source virtual machine 110 is configured in form (such as network (network) form).In general, each virtual machine has corresponding configuration text Part, and these configuration files are stored in the physical machine where virtual machine.
As shown in figure 3, in step S31, network disk 13 is mounted to target physical by carry unit 101 in a manner of the second carry On machine 12.Second carry mode is different from the first carry mode, and the second carry mode is, for example, NBD (Network Block Device, network control techology).
In step S32, setting unit 102 sets virtual machine to match according to disc format corresponding with the second carry mode It puts.Specifically, such as disc format corresponding with the second carry mode NBD is block (block) form, then setting unit 102 Virtual machine configuration is set according to block format.
Then, in step S33, unit 103 is established according to above-mentioned virtual machine configuration, target is established on target physical machine 12 Virtual machine 120.In this way, the configuration of target virtual machine 120 is consistent with the second carry mode NBD.
In step S34, thermophoresis unit 104 is by the internal storage data of source virtual machine 110 and status data thermophoresis to target Virtual machine 120, wherein, status data refers to the status data of source virtual machine 110, the e.g. number in relation to network interface card, serial ports etc. According to.In addition, thermophoresis unit 104 carries out above-mentioned thermophoresis operation according to existing live migration of virtual machine method, therefore here not Thermomigration process is described in detail.
Next, in step S35, the operational objective virtual machine 120 on target physical machine 12 of running unit 105 so that mesh It marks virtual machine 120 and uses network disk 13.Here, after target virtual machine 120 having been run on target physical machine 12, destination virtual Machine 120 can use the NBD in a manner of the second carry to be mounted to the network disk 130 on target physical machine 12.At this point, network disk 13 is just The NBD in a manner of the second new carry has been mounted in different physical machine (that is, target physical machine 12).
Further, device 10 further includes unloading unit 106.In step S36, in running unit 105 in target physical machine 12 After upper operational objective virtual machine 120, unloading unit 106 unloads network disk 13 from source physical machine 11.In this way, it can realize Network disk 13 is changed to be mounted to target physical with the second unloading manner from source physical machine 11 is mounted in a manner of the first carry Machine 12.
It, can when the first carry mode is there are problem or when needing to be updated the first carry mode by the present invention In a manner of changing the carry of network disk online, that is, in a manner of new (or newer) second carry by network disk be mounted to The different target physical machine of source physical machine, in this way, the present invention can be by simple, quick and improve network disk in a manner of success rate is high Performance and stability.
Further, target virtual machine is configured according to disc format corresponding with the second new carry mode, because This can be with the conversion of the type of canbe used on line virtual machine, such as the source virtual machine of common type is converted to the mesh of High Availabitity type Mark virtual machine.
Further, during online change as described above, without carrying out the shutdown operation of source virtual machine, therefore not Any influence can be generated to the use of user.
Further, during change as described above online, it is only necessary to the internal storage data of thermophoresis source physical machine and Status data, without migrating the data of network disk, therefore the data volume migrated can greatly reduce.
In addition, the present invention also provides a kind of non-volatile memory medium, it is stored on the non-volatile memory medium The program of carry is carried out to network disk, described program is computer-executed to implement the method for carrying out network disk carry, the journey Sequence includes：The network disk is mounted in a manner of the second carry on target physical machine by mounting instructions；Setting instruction, according to The second carry mode corresponding disc format sets virtual machine configuration；Instruction is established, according to the virtual machine configuration, Target virtual machine is established on the target physical machine；Thermophoresis instructs, by the internal storage data and status data of the source virtual machine Thermophoresis is to the target virtual machine；Operating instruction runs the target virtual machine so that described on the target physical machine Target virtual machine uses the network disk.
Although by being described in conjunction with specific embodiments to the present invention, for the ordinary artisan of this field, Many replacements, modification and variation according to making after mentioned above will be apparent.Therefore, when such replacement, modification When being fallen within the spirit and scope of appended claims with variation, it should be included in the present invention.
