The executive agent of the method for present embodiment can be the virtual machine (vm) migration decision making device, and it can be a specific virtual machine, also can be the functional module that is integrated in a certain the particular virtual machine.It can be arranged on source platform or the target platform, perhaps is arranged on the third party's virtual platform that is different from source platform and target platform.
The embodiment of the invention before virtual machine (vm) migration target platform is carried out the attribute inspection and/or integrality confirms, makes the migration decision-making according to attribute check result and/or integrality validate result, has effectively guaranteed the security and the confidence level of virtual machine (vm) migration.
Further embodiment of this invention provides a kind of virtual machine (vm) migration decision-making technique, as shown in Figure 1, comprises the steps:
Step 10: the migration request that the reception sources platform sends;
The migration request that the embodiment of the invention is sent by virtual machine (vm) migration decision making device reception sources platform;
The sign that comprises the target platform of described source platform appointment in the described migration request alternatively;
Alternatively, after source platform and virtual machine (vm) migration decision making device connected, virtual machine (vm) migration decision making device and described source platform carried out the identity legitimacy checking mutually; Perhaps described source platform is carried out the identity legitimacy checking by the virtual machine (vm) migration decision making device; The described identity legitimacy checking content embodiment of the invention is not done concrete qualification;
Alternatively, the virtual machine (vm) migration decision making device can carry out integrality confirmation (Integrity attestation) to described source platform.
Step 11: determine target platform according to described migration request;
Described definite target platform includes but not limited to following three kinds of methods:
Carry described target platform sign in the described migration request, determine target platform according to described target platform sign; Or
Obtain described source platform attribute information, determine target platform according to described source platform attribute information; For example, the virtual machine (vm) migration decision making device can determine that according to the attribute information of source platform target platform should have identical attribute specification; Also can be according to predetermined migration strategy, define a scope of the attribute specification that is complementary with the source platform attribute information, after determining the scope of target platform attribute specification or attribute specification, the virtual machine (vm) migration decision making device can find the sign of the target platform that satisfies attribute specification according to institute's interior virtual platform attribute information of (management) scope of being responsible for of this locality storage; Perhaps to be responsible for virtual platform broadcast request in (management) scope, carry message for seeking the target platform that satisfies such attribute specification, the target platform that meets the demands can return to similar information such as the virtual machine (vm) migration decision making device " satisfies the attribute specification as target platform "; Or
Carry the attribute specification of described source platform in the described migration request, determine target platform according to described attribute specification to target platform.
Step 12: described target platform is carried out attribute inspection and/or integrality confirmation, obtain attribute inspection and/or integrality validate result;
If need carry out the attribute inspection to target platform, then before carrying out the attribute inspection, obtain the target platform attribute, the method of obtaining the target platform attribute includes but not limited to: preserve platform sign and the corresponding attribute be responsible for to some extent in the scope in described virtual machine (vm) migration decision making device, search corresponding attribute according to the target platform of determining in the step 11; And/or, obtain the target platform attribute alternately with target platform;
Described target platform attribute includes but not limited to: software and hardware manufacturer, version information and system's basic configuration to target platform are checked; Described system basic configuration comprises: internal memory, hard-disk capacity, CPU, operating system version number, virtual level version number and/or software developer.
If the virtual machine (vm) migration decision making device is not understood the attribute specification of source platform to target platform, then also need to obtain the attribute specification of source platform to target platform before target platform is carried out the attribute inspection, the described source platform that obtains includes but not limited to the method for the attribute specification of target platform:
Obtain described source platform attribute information, obtain the attribute specification of described source platform target platform according to described source platform attribute information; Or
From described migration request, obtain the attribute specification of described source platform to target platform.
Describedly target platform carried out the method that integrality confirms comprise:
