In the specific implementation, above steps can be completed by method, the device of realizing virtual machine (vm) migration the embodiment of the present invention.Below above steps is elaborated:
Preferably, as a kind of embodiment, before described step S100, also comprise the steps:
Regularly do heartbeat detection by IP according to the default time cycle, detect the running status of the multiple physical hosts that move in group system, and determine the source physical host breaking down.
In above-mentioned steps, do heartbeat detection by IP, physical host passes through heartbeat path, periodically send the test pack of mutual detection, if in the multiple physical hosts that now move in group system, certain physical host breaks down (as: hard disk, internal memory, CPU, mainboard, I/O plate and power fail), now this physical host can not produce response (losing continuously the detection bag of setting number), so judge that this physical host breaks down, at this moment can determine the source physical host breaking down.
Preferably, as a kind of embodiment, in described step S100, described definite virtual machine (vm) migration order specifically comprises the following steps:
According to the configuration information of the virtual machine obtaining, judge whether predefined migration order, if so, determine that virtual machine (vm) migration order is predefined migration order; If not, determine that virtual machine (vm) migration order is the virtual machine creating time sequencing in configuration information;
The configuration information of described virtual machine comprises: the size information of virutal machine memory, multiple virtual machine creating time sequencing information or predefined migration order information.
In the invention process, after determining the source physical host breaking down, on inquiry fault physical host, there is which virtual machine, clear and definite which one or more virtual machine will be migrated on other most suitable target physical main frames;
User can analyze and learn according to the configuration information of virtual machine, is set with under migration order information condition user, needs predefined migration order; Do not setting under the condition of migration order, the migration order according to virtual machine creating time (configuration information of virtual machine) order as virtual machine, wherein, the time sequencing that described virtual machine (vm) migration order is virtual machine creating from front to back order is arranged.
Preferably, as a kind of embodiment, described physical host resource using information comprises current physical host free memory and current physical host CPU usage.
Further, as a kind of embodiment, in described step S200, describedly carry out physical host sequence according to resource using information priority and specifically comprise:
According to the size of current physical host free memory, carry out descending sort;
If the magnitude difference of arranging current physical host internal memory adjacent in rear sequence, lower than default memory threshold, according to CPU usage size, is carried out ascending order to described adjacent physical host and is arranged also final definite described physical host sequence;
Wherein, described default memory threshold is 128M.
In above-mentioned steps, analyze physics host resource and use information, determine the priority of the sink virtual machine resource (mirror image) of physical host, the sequence of execution physical host, inquiry obtains the resource of the physical host of normal operation under cluster, current physical host CPU usage, current physical host free memory size, first press current physical host free memory size as order standard, sort from big to small, if memory size is more or less the same (difference 128M in), the little physical host rank of CPU usage is front.
Preferably, as a kind of embodiment, described default horizontal redundancy condition is: the free memory of carrying out the target physical main frame after virtual machine (vm) migration is less than 20% of the total internal memory of physical host;
The free memory size of the target physical main frame after described virtual machine (vm) migration equals current physical host free memory size and deducts the size of the virutal machine memory that moves to described physical host.
Further, as a kind of embodiment, further comprising the steps of after the migration operation of the multiple virtual machines of described execution:
Multiple virtual machine (vm) migrations are to after target physical main frame, recover the original running status of virtual machine and revise the physical host of multiple virtual machines under respectively to operate the configuration information changing because of virtual machine (vm) migration.
In above-mentioned steps S300, illustrate, first the most front First virtual machine correspondence of sequence in described virtual machine (vm) migration order is migrated to the most front target physical main frame of physical host collating sequence, after First virtual machine (vm) migration EO, if the virutal machine memory that when now the free memory of the most front target physical main frame after First virtual machine (vm) migration is less than 20% condition of the total internal memory of this physical host, the memory source of (reaching default horizontal redundancy condition) or the most front target physical main frame can not meet current needs migration takies resource, next physical host in selection physical host collating sequence is as new target physical main frame, continue second virtual machine (vm) migration in virtual machine (vm) migration order to new target physical main frame, like this repetitive sequence carry out multiple virtual machines migration operation until the migration of all virtual machines all finish.
Obviously, First virtual machine target physical main frame is to arrange the most front physical host, and the free memory size of the target physical main frame after this physical host migration is that the memory size (size of current physical host internal memory) before this physical host migration deducts the virutal machine memory size that moves to this physical host; After First virtual machine (vm) migration, if meeting second virutal machine memory, this physical host internal memory takies resource (not reaching default horizontal redundancy condition simultaneously), to continue be the target physical main frame of second virtual machine to this physical host, until this physical host free memory is less than after total internal memory 20%, migration goal displacement is next physical host, determines the migration target physical main frame of each virtual machine by this rule;
For the method that realizes virtual machine (vm) migration that illustrates that better the embodiment of the present invention provides, be illustrated virtual machine about the step that realizes sequence and virtual machine (vm) migration for an actual example.For instance:
Following physical host and virtual machine are installed in a group system:
Like this, carry out physical host sequence according to resource using information priority, the order after physical host sequence is: physical host 3, physical host 1, physical host 2.
Virtual machine sequence is: VM1, VM2, VM3.
First, VM1 carries out and migrates to the operation of target physical main frame 3, and after migration, the free memory value of target physical main frame equals memory value that physical host free memory value before migration subtracts VM1: 6G-2G=4G;
Second step, judge that whether the free memory value of target physical main frame 3 after migration meets second virutal machine memory (VM2 in save as 2G) and take resource (not reaching default horizontal redundancy condition simultaneously), obviously target physical main frame 3 is using the target physical main frame as VM2; After VM2 migration, target physical main frame machine 3 free memories are: 4G-2G=2G; Now can not meet the 3rd virutal machine memory (VM3 in save as 3G) and take resource;
The 3rd step, according to physical host clooating sequence, next physical host in selection physical host collating sequence is as new target physical main frame (physical host 1), continue extremely new target physical main frame of the 3rd virtual machine (vm) migration in virtual machine (vm) migration order, the free memory of the target physical main frame 1 at the VM3 place after migration is like this: 5G-2G=3G.
Follow-up migration and execution virtual machine recovering step are with step S100 ~ step S300 similarity in the embodiment of the present invention, and it is no longer repeated.
