The resource regulating method that the embodiment of the present invention provides is applied to resource scheduling system, and this system comprises administrative center and is controlled by multiple servers of this administrative center.Each server in resource scheduling system is without the need to periodically reporting the load information of self to administrative center, but server is when identifying own load and being higher, the server that other the load of being moved out in resource scheduling system by the virtual machine of self of making decisions on one's own is lower, thus make the resource in resource scheduling system reach balanced.Fig. 1 is the schematic flow sheet of a kind of resource regulating method that the embodiment of the present invention proposes, and with reference to figure 1, method comprises:
Step 101: server obtains the load information of self when Preset Time arrives, and judges the virtual machine state of self according to load information;
Wherein, load information refers to the service condition of server to various resource.
Preset Time, periodically obtains the load information of self for server, make server can know the virtual machine state of self in time.
In practical application, judge virtual machine state according to load information, be specially: if load information is greater than default load value, then virtual machine state is high load condition; If load information is less than or equal to default load value, then virtual machine state is low load condition.Wherein, high load condition, illustrates the load too high of server, and the virtual machine of this server that needs to move out is to reduce the load of server; Low load condition, illustrates that the load of server is lower, and the virtual machine that can accept other servers is moved into the resource in balanced resource scheduling system.
Further, server obtains self load information when Preset Time arrives, specifically comprise: server obtains at least one resource information when Preset Time arrives, and to each resource information by normalized, calculates the load information of server.
The load information of server, comprise the load information of the multiple resources of server, such as, comprise the central processing unit (CPU of server, CentralProcessingUnit) service condition of occupancy, memory usage, free memory, network I/O (I/O, input/output), storage I/O.Certainly, the load information of server, also comprises the load information of other resources of server, and the embodiment of the present invention does not do concrete restriction to this.
Preferably, server obtains at least one resource information when Preset Time arrives, and to each resource information by normalized, calculate the load information of server, specifically comprise: server obtains the resource utilization of at least one resource when Preset Time arrives; Calculate the weight of the resource utilization of each resource; According to the weight of the resource utilization of each resource, calculated the load information of server by weighting normalization.
By utilizing the mode of weighting normalization to calculate the load information of server to the resource utilization of each resource, consider the service condition of the various resources of server, the load information of server can be calculated more exactly, make the use of server to self various resource be tending towards balanced.
Step 102: when the virtual machine state that server judges self is high load condition, to move out information according to the load information generating virtual machines of self, and the described virtual machine information of moving out is sent at least one other server, wherein, virtual machine is moved out information, comprises the information of the virtual machine that described server needs are moved out to other servers;
Wherein, other servers, refer to other the server in the resource scheduling system at this server place, and that is, this server and other servers belong to same resource scheduling system, are controlled by same administrative center.
In order to promote the resource utilization of each server, each server all runs multiple virtual machine.When the virtual machine state of server is high load condition, need the virtual machine selecting needs to move out to other servers in multiple virtual machines of server according to actual conditions, to reduce the load of server.
It should be noted that, server sends virtual machine at least one other server and to move out information, and namely by the mode of inquiring, server goes to judge whether other servers can move into virtual machine.So, server, without the need to reporting own load information to administrative center and waiting for that administrative center makes decision, achieves autonomous analysis decision, decreases the dependence to administrative center.
Further, server to be moved out information according to the load information generating virtual machines of self, specifically comprise: described server judges that the load of self virtual machine is less than default virtual machine load value and must not runs on described server, be then judged to allow virtual machine of moving out by described virtual machine; Described server calculates the load information of self moving out and to allow described at least one to move out after virtual machine, and judges the virtual machine state of now described server; If now the virtual machine state of described server is low load condition, then according to described in move out at least one allow virtual machine of moving out, generating virtual machines is moved out information.
It should be noted that, if virtual machine load is more than or equal to default virtual machine load value, virtual machine load too high is described to there is virtual machine like this and to move out risk; If virtual machine must run on server, such as, this virtual machine has the licence running on server, then this virtual machine does not allow server of moving out.
In actual applications, server preferentially can be moved out and is greater than the virtual machine of default working time working time from multiple virtual machine that allows to move out.Be greater than the virtual machine of default working time working time, illustrate that this virtual machine is stable, be therefore suitable for this virtual machine of moving out.
Step 103: other servers receive virtual machine and to move out information, when judging that the virtual machine state of self is low load condition according to own load information, utilize the load information of self to calculate virtual machine to move into parameter, and parameter of being moved into by virtual machine is sent to server;
Wherein, virtual machine is moved into parameter, represents that other servers can the sink virtual machine degree of moving into.Virtual machine parameter of moving into is higher, illustrates that the virtual machine of the more acceptant server of other servers is moved into; Virtual machine parameter of moving into is lower, illustrates that the virtual machine that other servers should not accept server is moved into.Specifically, virtual machine parameter of moving into be moved out information acquisition according to the load information of other servers and virtual machine.Further, the load information of other server by utilizing self calculates virtual machine and to move into parameter, specifically comprise: currently do not have virtual machine to move into if other servers described identify according to the load information of self, and self there is the resource running in described server virtual machine corresponding to information of moving out with described virtual machine, then other servers described to judge to move into after virtual machine corresponding to information of moving out with described virtual machine the virtual machine state of self; When the virtual machine state of other servers described is low load condition, the virtual machine that the information of moving out with described virtual machine that allows to move into is corresponding, and utilize own load information S
oldwith the load information S after virtual machine of moving into
new, according to formula: A=(1-(S
new-S
old)) × (1-S
old), calculate virtual machine and to move into parameter A.
In actual applications, other servers comprise according to the current process whether having virtual machine moving into of the load information identification of self: if the load information that other servers identify self increases gradually in regular hour section, then the confirmation of other servers is current has virtual machine to move into; If the load information that other servers identify self remains in default fluctuation range in regular hour section, then the confirmation of other servers is current does not have virtual machine to move into.
Step 104: server receives the virtual machine that at least one other server sends and to move into parameter, selects other servers that maximum virtual machine is moved into corresponding to parameter as destination server;
In actual applications, in the certain hour of server after moving out information at least one other server transmission virtual machine, the parameter if the virtual machine not receiving the transmission of other servers is moved into, then illustrate that these other server network links are bad or virtual machine cannot be provided in time to move into parameter, so just do not consider these other servers as destination server.
Step 105: server to be moved out virtual machine to destination server according to virtual machine information of moving out.
