Fig. 1 is the process flow diagram of operation system example creation method embodiment one of the present invention.The present embodiment is applicable to have main (Primary) operation system example and at least one many kernel operating system from (Secondary) operation system example, is applied to the scene needing dynamic creation to have the Secondary operation system example of autonomous system resource.Concrete, the present embodiment comprises the steps:
101, master operating system example receives the request to create of instruction establishment from operation system example, and request to create carries the resource requirement information from operating system.
In many kernel operating system, Primary operation system example also can be referred to as heavyweight operating system (Heavy OS), it is the general-purpose operating system with functions such as Resourse Distribute, recovery, virtual and coordinations, also be the operation system example that first starts on hardware, be responsible for the management of system resource, such as, the resources such as cpu resource, physical memory partitioned resources, physical equipment or the virtual unit in multiprocessor operations system are controlled.Secondary operation system example also can be referred to as lightweight operating system (Light OS), be the resource that manages based on Heavy OS and create the operating system of customization, the resource of self can only be managed, apply for resource from Heavy OS, or return to Heavy OS after resource being discharged.In this step, when certain application service initiated by needs, user proposes to create the request to create starting Secondary operation system example in the environment or interface of Primary operation system example, resource requirement information needed for this application service is provided simultaneously, such as, the number of the CPU of demand, the size etc. of physical memory subregion.
102, master operating system example is according to resource requirement information, and for distributing exclusive system resource from operation system example, system resource at least comprises: processor resource, physical memory partitioned resources.
After receiving the resource requirement information needed for the generation of Secondary operation system example, Primary operating system from resource pool for Secondary operation system example distributes exclusive system resource, such as, exclusive CPU, the device resources such as exclusive physical memory subregion, exclusive virtual unit or physical equipment.
103, master operating system example is according to resource requirement information, generates the resource description information from operating system.
Primary operating system is according to the resource requirement information in the Secondary operation system example request to create received, for generating the resource description information of specific data structure from operation system example, such as, under Huawei is subsidized, many kernel operating system that the Chinese Academy of Sciences develops: Rainforest operating system, generate the resource description information of start-up parameter data structure Kernbootparams.
Optionally, Primary operating system can adopt following several mode to be that Secondary operation system example generates resource description information:
Mode one, master operating system example are according to resource requirement information, the first resource descriptor of the quantity information of descriptive system resource is generated at client layer, and at kernel spacing, according to quantity information, generate from the complete resource description information of operating system, to make from operation system example, resource description information to be loaded with the physical memory subregion system resource.
Concrete, master operating system can first according to resource requirement information, the first resource descriptor of the quantity information of descriptive system resource is constructed at client layer, by the relevant information of required system resource, as the number of CPU, the number of Core, the size of physical memory subregion, the information etc. of the system map file corresponding with application service are filled in the first resource descriptor being formed in resource description information and describe quantity information.Then, by function call etc., the first resource descriptor that client layer generates is transferred to kernel spacing, continue to fill first resource descriptor at kernel spacing, such as, the information of the concrete CPU corresponding with required CPU number, the information of the concrete physical memory subregion corresponding with the size of required physical memory subregion add in first resource descriptor, thus generate finally complete resource description information, then make from operation system example, resource description information to be loaded with the physical memory subregion system resource.
Mode two, master operating system example, at kernel spacing, generate the resource description information from operation system example, to make to load resource description information with the physical memory subregion system resource from operation system example.Concrete, Primary operating system, at kernel spacing, directly according to resource requirement information, generates the resource description information that Secondary operation system example is complete.
Mode three, build resource description information from operation system example, directly loading on the physical memory subregion into distributing from operation system example, reading from memory headroom by from operating system.

In this step, Primary operation system example initializing system resources, and the related resource preparing that Secondary operation system example starts, as x86 framework CPU to be transformed into springboard (Trampoline) code etc. of protected mode from real pattern.
It should be noted that, above-mentioned 103 and 104 do not have strict sequencing, and in namely actual implementation process, first can generate resource description information, reinitialize system resource; Or, also can first initializing system resources, regeneration resource description information.
105, master operating system example starts from operation system example on initializing system resources.
After system resource initialization, Primary operation system example runs Secondary operating system nucleus code etc. on initializing system resources, thus creates startup Secondary operation system example.
The operation system example creation method that the embodiment of the present invention provides, Primary operating system is according to resource requirement information, for Secondary operation system example distributes exclusive system resource, after generating the resource description information of Secondary operation system example, initialization also starts Secondary operation system example, thus the resource requirement that realization provides according to user, dynamic establishment has the operation system example of exclusive resource, reach and improve system extension performance, and meet the object of the demand of user.
Further, in above-described embodiment one, master operating system example receives instruction and creates from after the request to create of operation system example, according to resource requirement information, before distributing exclusive system resource, according to resource requirement information, can judge in resource pool, whether to there is the system resource meeting resource requirement information.
Concrete, Primary operation system example can according to resource requirement information, judge whether resource idle in resource pool exists the resource meeting resource requirement information, such as, can according to CPU distribution state bitmap (MP Table), judge current idle can CPU or Core, or, discharge by other means, as hot plug (Hotplug) mode discharges the CPU in other Secondary operation system examples, the CPU of recovery is distributed to current Secondary operation system example to be created.
Further, in above-described embodiment one, from the angle of bootup process standard (multiboot), comprise compatible resource description information and the resource description information of standard from the resource description information of operation system example, the resource description information meeting multiboot is referred to as the resource description information of standard; Otherwise the resource description information not meeting multiboot is referred to as compatible resource description information.
In general, many kernel operating system can have many forms, such as, under Huawei subsidizes, the open source code virtual machine monitor (XEN) of the virtual technology of increasing income that the Rainforest operating system that the Chinese Academy of Sciences develops, Cambridge University safeguard, there is on XEN virtual machine access suggestion access authorization for resource, and the operating system (Demain0) of other word operation systems can be managed.Below, for Rainforest operating system, the present invention will be described in detail.
Concrete, a system be made up of (can also for a multiple) Primary operational instances and multiple Secondary operation system example in Rainforest system, Primary operation system example is responsible for the management etc. of life cycle of the integration of system resource, configuration, Secondary operation system example, and Secondary operation system example runs on the physical memory subregion of isolation.Wherein, following governing principle is had: first when carrying out subregion to system resource, the classification of equipment that (PCI-E, internal bus) is mutually isolated with physically, secondly, system resource can divide with the separate functional unit of physical equipment when cannot satisfy the demands, finally, just can consider to carry out virtual to single one physical equipment, upwards construct multiple virtual unit by time-multiplexed physical equipment.The Primary operation system example of Rainforest system comprises: operating system client layer value-added tax function (Osloader) module, CPU control (CPU Controller) module and springboard (Trampoline) module, the Secondary operation system example request to create that Primary operation system example sends with Osloader functional module response user, Secondary operation system example is created via CPU Controller module drive, and complete patten transformation by Trampoline module, roughly comprise the steps:
S1, Primary operation system example receives the request to create creating and start Secondary operation system example.
